Westlake GA7501 is an anhydride modified acrylate copolymer designed for extrusion coating and cast film tie layers. This resin is designed to function as a coextruded tie layer in multilayer applications where more heat resistance is required than typical acrylate polymers provide. Westlake GA7501 is designed to tie polyethylene or polyester to resins that typically have poor bonding characteristics such as polyamide and EVOH. This polymer can also be used as a compatibilizer for compounding dissimilar resins.
