Polymer Process Aid

Polymer Process Aid (PPA) masterbatches are based on fluoropolymers / fluoroelastomers and are generally used for extrusion process of polyolefins. They migrate from the polymer melt and coat the metal surfaces of extruder wall and the die region which provides a lubricating effect. This reduces the stress on the polymer melt at the die exit and helps eliminate melt fracture / shark skin effect.

Polymer Process Aid

Eliminate Die Build up thus increase productivity due to lesser frequency of stoppage for die cleaning

Reduce back pressure

Increase speed of extrusion without melt fracture
and thus increasing output

Reduce time and material required for colour changeovers

Reduce temperature of processing and thus lower energy costs

Improve gloss and surface finish

Reduce polymer gels in the product

Typical end product applications are LLDPE films, HDPE Pipes, Cables and blow moulded bottles, PP sheets, foams, cast and oriented films.


A higher dosage is required to condition the extruder while starting so that adequate fluropolymer is available to coat the metal surfaces. A lower maintenance dose is required during continuous Products to supplement the fluorpolymer which is gradually abraded from surfaces.
