Q1: What types of polymers is Cathay Masterbatch Red AP315 compatible with?
A: Cathay Masterbatch Red AP315 is formulated for excellent compatibility with common thermoplastics including polyethylene (PE), polypropylene (PP), and polystyrene (PS). It demonstrates good thermal stability during extrusion and injection molding processes typical for these resins.
Q2: Is this pigment suitable for food-contact applications?
A: Cathay Masterbatch Red AP315 is based on inorganic pigments known for high chemical inertness and low extractability. While it is not pre-certified for food contact, its composition aligns with general requirements for indirect food-contact plastics when incorporated into compliant base resins and processed under appropriate conditions. End-use compliance must be verified by the compounder or converter per applicable regional regulations.
Q3: How should this masterbatch be stored to maintain performance?
A: Store in a cool, dry location away from direct sunlight and sources of heat or humidity. Keep containers sealed tightly after opening to prevent moisture absorption and avoid contamination. Under proper storage conditions, shelf life typically exceeds 12 months from date of manufacture.
