As high-performance reinforced functional masterbatches in plastic processing, mica and kaolin masterbatches are highly favored for their reinforcement, barrier property, heat resistance and cost-effectiveness. Made from natural high-purity mica and kaolin minerals, they effectively optimize the mechanical and functional properties of plastic products, and are widely used in packaging, home appliances, construction and other fields. ANGFLY, a professional masterbatch manufacturer, introduces the core features and applications of mica/kaolin masterbatch.
Mica/Kaolin Masterbatch: Core Advantages of Reinforcement & Barrier
ANGFLY mica/kaolin masterbatch is made of high-purity natural mica (flake structure) and kaolin powder, matched with PE/PP carrier resin, high-efficiency dispersants and coupling agents, through professional internal mixing and twin-screw extrusion processes. Compared with pure mineral powder, it has excellent dispersibility and compatibility with base resins, avoiding agglomeration and ensuring stable processing efficiency.
Their core advantages lie in excellent reinforcement and dimensional stability: the flake structure of mica and the fine particle characteristics of kaolin can form a dense “support network” in the plastic matrix, significantly improving the rigidity, flexural strength and impact resistance of products, reducing shrinkage and warpage, and ensuring the dimensional accuracy of finished products.
In addition, they have outstanding barrier and heat resistance: mica’s flake structure can effectively block the penetration of gas and moisture, improving the barrier property of plastic packaging; kaolin enhances the heat resistance of products, making them suitable for medium and high-temperature processing and use scenarios. Meanwhile, they can reduce the dosage of expensive resins, achieving cost-saving effects without affecting product performance.
ANGFLY’s mica/kaolin masterbatch features uniform particle size, good fluidity and stable batch consistency, with no impurities or spots during processing. It is non-toxic, odorless, and certified by SGS, ROHS and FDA, meeting the requirements of food contact and environmental protection.
Professional Applications
Compatible with PP, PE, ABS, PVC and other mainstream resins, and adaptable to injection molding, extrusion, film blowing and other processes, they are widely used in:
1. Packaging Industry: Food packaging films, barrier sheets and hollow containers, enhancing gas and moisture barrier properties, extending the shelf life of products; packaging for daily chemicals and medicines, meeting safety and environmental protection standards.
2. Home Appliances & Construction: Plastic parts of home appliances (shells, internal components), improving rigidity and heat resistance; construction materials (decorative panels, pipe fittings), enhancing weather resistance and dimensional stability, suitable for indoor and outdoor use.
3. Other Fields: Automobile interior parts (instrument panels, door panels), improving impact resistance and heat resistance; non-woven fabrics and plastic toys, ensuring safety and structural stability.
