Description

Poly(Ethylene-Co-Ethyl Acrylate-Co-Maleic Anhydride) is a versatile, functionalized ethylene copolymer engineered to enhance adhesion, compatibility, and reactivity in polymer blends and composites. This terpolymer is valued for its ability to act as a coupling agent and impact modifier, improving the mechanical properties and processability of various engineering plastics. It is essential for manufacturers in the plastics compounding, wire & cable, and adhesive industries seeking to upgrade material performance.

Application

• Polymer Compatibilizer: Used to improve the interfacial adhesion and dispersion in blends of polar and non-polar polymers (e.g., polyolefin/polyamide, polyolefin/polyester).
• Adhesion Promoter: Serves as a primer or additive in coatings, inks, and adhesives to enhance bonding to metal, glass, and other polymer substrates.
• Impact Modifier: Incorporated into engineering thermoplastics like polyamides (PA) and polyesters (PBT, PET) to increase toughness and low-temperature impact strength.
• Wire & Cable Jacketing: Imparts excellent stress-crack resistance and flexibility in halogen-free flame retardant (HFFR) compounds for insulation and sheathing.
• Reactive Processing Aid: The maleic anhydride groups can react with amines or hydroxyls, enabling in-situ grafting for customized polymer modifications.
• Filler Coupling Agent: Improves the bonding between inorganic fillers (e.g., glass fiber, minerals) and the polymer matrix, leading to better mechanical properties.
