3M, 0.5 kg - 498.952 kg, Polymer Processing Additive, Chemical Additive, White to Off-White 3M Dynamar Polymer Processing Additive FX 5929M is a high-performance polymer processing additive designed to enhance the processing of thermoplastics. This granular additive, available in various package sizes from 0.5 kg to 498.952 kg, is a free-flowing fluoropolymer that improves extrusion processing, reduces die build-up, and lowers apparent melt viscosity in polyolefin resins. At very low use levels (typically 100-700 ppm), it doesn't alter the physical properties of high-strength plastics. Its exceptional utility is evident in low melt index film-grade linear low-density polyethylene (LLDPE), including metallocene linear low-density polyethylene (mLLDPE) and high-density polyethylene (HDPE). The additive is particularly effective in polyolefin resins containing anti-blocking agents, pigments, and other inorganic additives. 3M Dynamar FX 5929M contributes to increased output and improved film clarity and gloss.
