The use of PPA is not anymore limited to blown film extrusion exclusively: nowadays PPA are widely used in film production, pipe extrusion, blow molding, wire and cable production, coextrusion, fiber spinning… using LLDPE, MDPE, HDPE, and PP. Recently this list has even extended to non-polyolefins. Polymer Processing Additives (PPA) are frequently used in the plastics industry for the processing of polyethylene and polypropylene.
TapStar® PPA is suitable for PE & PP available in pellet form for injection, extrusion and blow moulding applications. We also offer TapStar® PPA 4032 in powder form for roto-moulding applications.
