| Westlake EMAC® SP2258 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. SP2258 provides excellent adhesion to polyolefins, polyesters, and other polymers while providing outstanding low temperature performance. |
