Westlake EMAC® SP2255 17% Ethylene-Methyl Acrylate Copolymer
Categories: Polymer; Thermoplastic; Ethylene Methyl Acrylate

Material Notes: Westlake EMAC® SP2255 is a 17% EMA copolymer containing slip and antiblock. This resin is designed for blown or cast film, tie-layers, and extrusions where flexibility, compatibility, or low heat seal temperatures are required. SP2255 provides excellent adhesion to polyolefins, polyesters, and other polymers while providing outstanding low temperature performance.

Applications: films, flexible packaging, disposable gloves, tubing and wound care.

FDA: This material complies with FDA regulations in 21 CFR, section 177.1340.
