High-Reactivity GMA Terpolymer AX8670T, EVA-GMA for Engineering Plastic Alloy Compatibilizer
AX8670T is high-reactivity EVA-GMA terpolymer supplied as free-flowing pellets. Glycidyl methacrylate functional groups on polymer chains can react with carboxyl and amine terminal groups of polar engineering plastics during twin-screw compounding. It functions as both compatibilizer and toughener for immiscible polymer blends. AX8670T reduces phase separation, refines dispersed phase size, boosts impact strength and improves dimensional stability of engineering plastic alloys. It is widely used
Product Detail PageChemical IdentityAX8670T is ethylene vinyl acetate-glycidyl methacrylate terpolymer produced via high-pressure polymerization. The polymer backbone carries reactive epoxy groups from GMA segments. It is delivered in pellet form, suitable for continuous feeding in twin-screw extrusion. The reactive epoxy groups form covalent bonds at the interface of different polymer phases under compounding temperature. The EVA backbone provides inherent flexibility, combining compatibilization and energy-absorbing toughening effect in one additive. It maintains good thermal stability under common processing temperatures of polar engineering resins.
Key PerformanceFlexible EVA segments absorb impact energy when alloy parts are subjected to mechanical shock. High reactivity GMA groups enhance interfacial adhesion between incompatible polymer matrices, limiting phase separation and suppressing crack propagation. AX8670T refines the morphology of blended polymer alloys, improving surface quality of injection molded products. It raises notched impact strength without severe deterioration of thermal performance in properly designed formulations. It exhibits stable melt behavior during extrusion compounding, helping compounders reduce formulation complexity by integrating compatibilizing and toughening performance.
ApplicationsAX8670T serves as compatibilizer and toughener for various engineering plastic alloy systems. It is widely used for blends containing nylon, PBT, PET and other polar thermoplastics. It fits glass fiber reinforced and mineral filled polymer alloy formulations. Typical end products include automotive plastic parts, electrical component housings, mechanical structural injection molded components. It is suitable for halogen-free compound projects in electrical and electronic fields.
Storage & HandlingStore AX8670T pellets in sealed original bags inside cool, dry and ventilated warehouse. Recommended storage temperature 10-30℃. Avoid direct sunlight and high humidity to prevent pellet caking. Anti-static protection is recommended during material conveying and feeding. Once packaging bag is opened, consume pellets rapidly to prevent moisture absorption. Do not stack pallets excessively high to avoid pellet crushing.
