1. Introduction to Sodium Sulfate Filler Masterbatch
1.1 Core Definition and High-Filling Compound Concept
Sodium sulfate filler masterbatch is a cost-efficient inorganic functional compound material widely adopted in modern plastic compounding and extrusion industries. Also known as salt cake filler masterbatch, it takes refined industrial sodium sulfate powder as the primary inorganic filling component, matched with polyolefin carrier resin, specialized dispersants, surface coupling agents and processing lubricants. Through high-shear kneading, uniform compounding and melt pelletizing via professional twin screw extruder and compounding extruder equipment, it forms high-concentration solid masterbatch particles for plastic filling modification.
High filling sodium sulfate compound masterbatch refers to the upgraded product with a sodium sulfate filling ratio exceeding 70% by weight, which breaks through the filling limit of conventional ordinary filler masterbatch. Compared with low and medium filling products, high filling sodium sulfate masterbatch features higher resin replacement rate, more prominent cost reduction effect and better dimensional modification performance. It has become one of the most popular low-cost filling solutions for general plastic products, packaging materials and daily plastic consumer goods.
Different from talc, calcium carbonate and other traditional fillers, sodium sulfate has ultra-low raw material cost, excellent whiteness, fine particle uniformity and stable chemical inertness. High filling sodium sulfate masterbatch not only effectively reduces the usage of expensive pure polymer resin, but also optimizes the rigidity, surface flatness and processing fluidity of plastic products. Professional production of high uniformity high filling sodium sulfate masterbatch completely relies on high-performance KERKE twin screw compounding extruder and masterbatch extruder equipment to solve industry pain points such as filler agglomeration, poor dispersion and low filling rate in traditional single screw extrusion production.
1.2 Industrial Development Background and Market Positioning
The global plastic processing industry is facing continuous rising raw material resin costs and increasingly stringent cost control requirements. Conventional calcium carbonate and talc filler masterbatches have limited cost reduction space due to relatively high filler prices, while high-end functional masterbatches cannot meet the mass production cost demands of low and medium-end plastic products. Sodium sulfate, as a by-product of chemical industry, has abundant global reserves and ultra-low market prices, with outstanding cost advantages as plastic inorganic filler.
In the past, sodium sulfate filler was limited by poor surface activity and difficult high-concentration dispersion, failing to achieve large-scale high filling compounding production. With the continuous upgrading of twin screw compounding extrusion technology and surface modification process, modern masterbatch extrusion equipment can realize uniform dispersion of ultra-high concentration sodium sulfate powder in resin matrix. High filling sodium sulfate filler masterbatch has gradually replaced traditional filling materials in packaging plastics, daily plastic products and industrial low-load plastic parts markets, forming a mature and large-scale industrial application system.
As a professional manufacturer of twin screw extruder, compounding extruder and masterbatch extruder, KERKE has long been committed to the process and equipment optimization of high filling inorganic masterbatch production. Targeted screw configuration and compounding process parameters are developed for the physical and chemical characteristics of sodium sulfate, providing complete high filling compounding production line solutions for plastic modification enterprises, greatly improving the production efficiency and finished product qualification rate of sodium sulfate masterbatch.
1.3 Core Application Values of High Filling Sodium Sulfate Masterbatch
The biggest core value of high filling sodium sulfate filler masterbatch is extreme cost optimization. Under the premise of ensuring basic mechanical properties and processing performance of plastic products, it can replace 30% to 60% of pure resin raw materials, greatly reducing the comprehensive raw material cost of plastic products. Compared with ordinary calcium carbonate masterbatch, the comprehensive cost of sodium sulfate modified plastic products can be further reduced by 10% to 18%, with extremely high economic benefits for mass-produced ordinary plastic products.
In terms of product performance, high-purity sodium sulfate filler has high whiteness, which can improve the surface gloss and color uniformity of plastic products, avoiding the yellowing and darkening problems of some low-cost fillers. Its fine particle structure can optimize the melt fluidity of modified plastics, reduce extrusion and injection molding processing resistance, and lower equipment operating energy consumption. In addition, sodium sulfate has stable chemical properties, no water absorption, no deterioration and no chemical reaction with polymer resin, ensuring long-term stable performance of modified products.
2. Physical and Chemical Characteristics of Industrial Sodium Sulfate Filler
2.1 Basic Physical Parameters of Sodium Sulfate
Industrial refined sodium sulfate used for high filling masterbatch production is a white anhydrous crystalline powder with uniform particle size and high purity. Its density is 2.68g/cm³, Mohs hardness is 2.5, with moderate hardness, which will not cause severe wear on the screw and barrel of twin screw extruder and masterbatch extruder equipment during high filling compounding production. The melting point of sodium sulfate is 884℃, which is far higher than the conventional plastic extrusion processing temperature of 160℃ to 260℃, ensuring no melting, decomposition or structural damage of the filler during thermal processing.
High-quality sodium sulfate filler for compounding production has a whiteness of over 92 degrees, low impurity content and uniform particle size distribution, which can ensure the high appearance quality of modified plastic products. Its good powder fluidity is conducive to uniform batching and stable feeding in automatic production lines, avoiding material bridging and intermittent feeding problems in high filling production, and providing stable raw material conditions for continuous compounding extrusion.
2.2 Chemical Stability and Processing Adaptability
Anhydrous sodium sulfate has excellent chemical inertness, does not react with acid, alkali, salt and organic polymer materials, and has strong corrosion resistance and weather resistance. It will not produce chemical decomposition, precipitation and color change during long-term use and high-temperature extrusion processing, ensuring stable physical and chemical properties of masterbatch and modified plastic products. Different from hygroscopic inorganic fillers, qualified anhydrous sodium sulfate has extremely low water absorption, effectively avoiding bubble generation, silver streaks and performance attenuation of melt products caused by filler moisture.
The only defect of pure sodium sulfate powder is poor surface compatibility with non-polar polyolefin resins, resulting in easy filler agglomeration and poor interfacial bonding in high filling state. Therefore, surface activation modification must be carried out through professional coupling agents in the compounding process. Combined with the high-shear kneading advantage of KERKE compounding extruder, the interfacial bonding force between sodium sulfate filler and resin matrix can be significantly improved, realizing stable production of ultra-high filling masterbatch.
2.3 Advantages and Limitations as Plastic Filler
In terms of advantages, sodium sulfate has ultra-low raw material cost, high whiteness, fine particle size and stable chemical properties, with comprehensive cost performance far exceeding traditional inorganic fillers. It has low equipment wear, good processing fluidity and excellent appearance modification effect, which is very suitable for high-volume and low-profit plastic product modification. In terms of limitations, sodium sulfate filler has limited mechanical reinforcement effect, slightly lower rigidity improvement effect than talc powder, and is not suitable for high-strength engineering plastic products. It is mainly applicable to ordinary packaging, daily necessities and low-load industrial plastic products.
3. Classification of High Filling Sodium Sulfate Filler Masterbatch
3.1 Classification by Filling Concentration
According to the sodium sulfate filling content, high filling sodium sulfate masterbatch is uniformly defined as products with filling ratio above 70%, subdivided into conventional high filling type (70%-80%) and ultra-high filling type (80%-88%). Conventional high filling masterbatch has balanced dispersion performance and cost reduction effect, stable product quality, low processing difficulty, suitable for most plastic modification scenarios, and is the mainstream product in the market.
Ultra-high filling sodium sulfate compound masterbatch has a filler content of more than 80%, with extremely high resin replacement rate and prominent cost advantages. However, it has high requirements on the shear dispersion performance and screw configuration of extrusion equipment, and can only be stably produced by high-performance KERKE twin screw compounding extruder. It is specially used for low-demand full filling plastic products with no strict requirement on mechanical strength, maximizing enterprise production economic benefits.
3.2 Classification by Carrier Resin Type
PP carrier high filling sodium sulfate masterbatch is the most widely used type, with polypropylene as the carrier resin, suitable for PP woven bags, packaging boxes, injection molding daily necessities and PP profile products. PE carrier masterbatch takes polyethylene as the carrier, with good low-temperature toughness, suitable for PE blown films, plastic bags, packaging films and low-temperature resistant plastic products.

Multi-functional composite high filling masterbatch adds anti-aging agent, lubricant and toughening agent on the basis of high sodium sulfate filling, which can reduce product cost while improving the weather resistance and toughness of modified products, suitable for medium-grade plastic packaging and outdoor plastic products.
4. Industrial Production Process of High Filling Sodium Sulfate Compound Masterbatch
4.1 Precision Raw Material Pretreatment and Activation Process
Raw material pretreatment is the core precondition for high filling masterbatch qualified rate, directly determining the dispersion uniformity of ultra-high concentration sodium sulfate filler. Firstly, screen and purify industrial sodium sulfate powder to remove large particle impurities and agglomerated blocks, and ensure uniform particle size of filler powder. Then, carry out professional surface activation modification treatment, spray silane coupling agent or titanate coupling agent evenly on the surface of sodium sulfate powder through high-speed mixing equipment, and conduct high-temperature stirring activation to improve the surface activity of filler and the compatibility with resin.
All carrier resins and auxiliary additives need to be dried and dehumidified to remove trace moisture, preventing melt bubbles, particle pores and product performance defects in high filling extrusion process. Standardized activation pretreatment can effectively solve the agglomeration problem of high concentration sodium sulfate filler, lay a foundation for uniform dispersion in subsequent compounding extrusion, and avoid common defects such as masterbatch particles with uneven texture and poor modification effect.
4.2 Automatic Proportioning and High-Speed Mixing Process
According to the preset high filling formula ratio (70%-88% sodium sulfate powder, 10%-28% carrier resin, 2%-5% functional auxiliaries), the automatic batching system realizes precise quantitative feeding of all raw materials, with a batching error controlled within ±0.3%, ensuring consistent formula of each batch of masterbatch products. The accurately proportioned raw materials are sent to a high-speed mixer for heating and stirring mixing, realizing preliminary uniform dispersion of filler, resin and auxiliaries, and eliminating primary filler agglomeration.
The high-speed mixing process adopts staged temperature control and timed stirring process to ensure that the coupling agent fully reacts with the filler surface and the lubricant is evenly coated on the material surface, improving the melt fluidity of high filling materials and reducing the shear processing resistance of subsequent compounding extruder equipment.
4.3 Twin Screw Compounding Extrusion Process (Core High-Filling Process)
Compounding extrusion is the most critical link in the production of high filling sodium sulfate masterbatch, which determines the filler dispersion degree, masterbatch stability and finished product quality. The uniformly mixed high filling materials are stably and quantitatively fed into the KERKE twin screw compounding extruder. Different from conventional low filling extrusion, high filling sodium sulfate compounding requires matched screw shear configuration and multi-stage temperature gradient control.
KERKE twin screw extruder adopts customized screw combination for high inorganic filling scenarios, equipped with dense kneading blocks, high-efficiency mixing elements and low-resistance conveying sections. This structural design can generate uniform high shear force in the melt state, fully peel and disperse sodium sulfate agglomerated particles, and realize uniform distribution of ultra-high concentration filler in the resin matrix. At the same time, the multi-stage zoning precise temperature control system avoids local overheating decomposition of auxiliaries and insufficient resin melting, ensuring stable melt plasticization state and continuous and uniform extrusion output.
In the high filling compounding process, the closed-loop pressure stabilization system of KERKE compounding extruder can automatically adjust the screw speed and feeding speed according to the melt pressure change, effectively solving the problems of unstable extrusion pressure and fluctuating output easily occurring in ultra-high filling production, and ensuring the consistency of each strand of extruded material.
4.4 Cooling, Pelletizing and Finishing Screening Process
The high filling composite melt extruded from the die head is cooled and shaped by water cooling or air cooling system to form smooth and uniform material strips. The low-temperature rapid cooling process avoids filler precipitation and melt layering of high filling materials, ensuring uniform internal structure of material strips. The cooled material strips are sent to a high-speed pelletizer for fixed-length pelletizing to produce cylindrical masterbatch particles with uniform particle size.
Finally, the finished particles are screened, dedusted and inspected to remove fine powder, oversized particles and defective hollow particles. After metal detection and sampling performance test, the qualified high filling sodium sulfate filler masterbatch is packaged and stored to ensure stable and consistent quality of finished products.
