Westlake EMAC® Plus SP1358 21.5% Ethylene-Methyl Acrylate Copolymer
Categories: Polymer; Thermoplastic; Ethylene Methyl Acrylate

Material Notes: Westlake EMAC® Plus SP1358 is a 21.5% 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. SP1358 is compatible with and provides excellent adhesion to polyolefins, polyesters, and other polymers while providing outstanding low temperature performance. The higher melting point of this EMAC® Plus grade offers EMA performance with improved heat resistance.

Applications: films, disposable gloves, and wound care.

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