N493 is maleic anhydride grafted POE compatibilizer supplied as free-flowing pellets, specially developed for nylon and polypropylene alloy systems. The grafted MAH functional groups can react with amine end groups of nylon during twin-screw melt compounding, forming strong chemical bonds at the phase boundary. The flexible POE backbone provides impact toughening effect simultaneously. N493 reduces phase separation of immiscible PA and PP, refines dispersed phase size, enhances notched impact st

Product Detail

Product Detail PageChemical IdentityN493 is POE-g-MAH copolymer produced by reactive grafting technology. Maleic anhydride is grafted onto the polyolefin elastomer backbone. It is delivered in pellet form for stable and continuous feeding in twin-screw extrusion. MAH functional groups on polymer chains react with terminal amine groups of polyamide under melt compounding temperature to build covalent interfacial linkage between PA and PP phases. The elastomeric POE segment retains good elasticity, combining compatibilization and toughening functions. It maintains excellent thermal stability under conventional PA/PP blend processing temperature without thermal decomposition.

Key PerformanceThe flexible POE elastomer absorbs impact energy when molded PA/PP alloy parts are subjected to mechanical shock. Grafted maleic anhydride strengthens interfacial bonding between nylon and polypropylene phases, suppressing phase separation and crack propagation. N493 greatly upgrades notched impact strength of PA/PP alloy, reduces water absorption brought by nylon, and improves dimensional stability of finished molded parts. It optimizes melt processing property of PA/PP blends and improves surface appearance of injection molded products. It works well for neat, glass fiber reinforced and mineral filled PA/PP alloy formulations.

ApplicationsN493 is mainly used as compatibilizer and toughener for PA/PP engineering plastic alloys. It fits glass fiber reinforced and mineral filled PA/PP blend compounds. Typical finished products include automotive interior and exterior plastic parts, electrical enclosures, mechanical structural components and corrosion-resistant injection molded parts. It is suitable for formulations requiring low water absorption, balanced toughness and dimensional stability. It can be adopted in halogen-free compound projects for electronic applications.

Storage & HandlingStore N493 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 required during pellet transfer and feeding. Once the packaging bag is opened, consume pellets promptly to avoid moisture absorption. Do not stack pallets excessively high to prevent pellet crushing under heavy weight.

Why Choose SupplierWe provide stable alternative grade N493 POE-g-MAH compatibilizer for PA/PP alloy compound manufacturers. Complete TDS and MSDS documents are available for export. Bulk container shipment and small trial orders are supported. Our additive helps overseas compound factories produce high-performance PA/PP alloy with improved interfacial bonding, impact resistance and low water absorption.
