Description

Poly(Ethylene-Co-Methyl Acrylate-Co-Glycidyl Methacrylate) is a specialized reactive terpolymer that combines the flexibility and processability of polyethylene with the adhesion-promoting properties of methyl acrylate and the crosslinking functionality of glycidyl methacrylate. This unique combination makes it an essential compatibilizer and impact modifier for enhancing the toughness and adhesion between dissimilar polymers. It is primarily used by manufacturers in the plastics compounding, automotive, and wire & cable industries to create high-performance polymer blends and composites.

Application

• Polymer Compatibilizer: Used to improve the compatibility and interfacial adhesion in blends of polar and non-polar polymers, such as polyamide/polyolefin or polyester/polyethylene blends.
• Impact Modifier: Enhances the toughness and impact resistance of engineering plastics and thermoplastic vulcanizates (TPVs).
• Adhesive & Tie-Layer Resin: Serves as a key component in multi-layer co-extruded films and sheets, bonding layers that would otherwise delaminate.
• Wire & Cable Jacketing: Improves adhesion between insulation layers and provides stress-crack resistance in cable sheathing applications.
• Automotive Components: Used in under-the-hood parts and interior trim where chemical resistance and durability are critical.
• Reactive Processing Aid: The epoxy groups from glycidyl methacrylate can react with carboxyl or amine end-groups during melt processing to form in-situ graft copolymers.
