Description
Polymer Process Aid (PPA) masterbatches are based on fluoropolymers/fluoroelastomers and are generally used for the extrusion process of polyolefins. They migrate from the polymer melt and coat the metal surfaces of the 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.
Features
- Improve gloss and surface finish
- Reduce polymer gels in the product
Advantages
- 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
