Zzyzx Polyethylene Impact Modifiers: toughness with rigidity. Unlike typical impact modifier and elastomer additives, Zzyzx Impact Modifiers increase strength without harming modulus.

zPoly231 is a modified ultra-high molecular weight polyethylene that blends well with HDPE, increasing impact strength while maintaining rigidity. Further, zPoly231 improves mold release for faster cycle time, and increases abrasion resistance.
