1. Core International Quality Standards for Commercial Color Masterbatches
Global mainstream markets have formed a complete set of mandatory and recommended quality standards for color masterbatches, covering safety and environmental protection indicators, color performance indicators, physical and mechanical properties, and batch stability. All exported color master products must pass corresponding standard detection and certification to avoid market access restrictions and order losses. The mainstream applicable international standards include EU REACH regulation, RoHS directive, FDA food-grade safety standard, ISO color detection standard and industrial plastic modification quality specification system, which jointly restrict the production and manufacturing of high-quality color masterbatches.
1.1 EU REACH & RoHS Environmental Safety Standards
The EU REACH regulation is the core environmental access standard for plastic masterbatch products, strictly limiting the content of harmful substances such as heavy metals, polycyclic aromatic hydrocarbons, phthalates and persistent organic pollutants in color masterbatches. The RoHS directive further restricts the use of lead, mercury, cadmium, hexavalent chromium and other harmful heavy metal elements in electronic and electrical plastic masterbatches. For color masterbatch production, unqualified extrusion equipment will cause incomplete decomposition and residual mixing of harmful additives and impure pigments, leading to excessive harmful substance detection and product non-compliance.
International standard compliant color masterbatch production requires equipment to achieve uniform mixing and full reaction of raw materials, avoid local enrichment of harmful impurities, and ensure that all substance indicators are within the standard limit range. Kerke masterbatch extruders adopt low-shear homogenizing plasticization technology, which can fully disperse and stabilize various additives and pigments without producing new harmful decomposition substances during the extrusion process, perfectly meeting REACH and RoHS full-standard detection requirements.
1.2 FDA Food-Grade Safety Standards for Food Packaging Masterbatches
Color masterbatches used in food contact packaging, beverage containers and food-grade plastic products must comply with US FDA food safety regulations and EU food contact material standards. The core detection indicators include no harmful substance precipitation, stable high-temperature resistance, no migration of pigment molecules, and no odor residue. Ordinary extruders have unstable plasticization temperature and poor impurity filtration performance, which easily cause additive precipitation and pigment migration, failing food-grade safety certification.
