Ultra-high molecular weight siloxane polymer pre-dispersed at 50% in a HDPE carrier, supplied as free-flowing white pellets. Migrates slowly to the surface during processing, which raises melt flow and output, lowers coefficient of friction, and improves scratch, mar and abrasion resistance of the finished part without the surface defects or paint adhesion loss caused by conventional slip additives. Recommended for HDPE.
