Why Choose Us
In today’s times, neither poor appearance nor reduced output is acceptable. But, both these problems can be easily solved. PPA improves both, the quality and profitability of the extrusion process. While it can offer performance and cost advantages, Welset polymer processing aids are designed to improve the melt processability of polymers. They can also give finished articles improved aesthetic properties by improving partial gloss and clarity. It can reduce or eliminate melt fracture and can reduce machine torque.
Welset’s polymer processing aid masterbatch is based on fluoropolymer technology. The fluoropolymer has a high affinity for metal and forms a low friction surface coating on the extruder screw, barrel and die which enables the polymer melt to flow with less resistance.
Special Features
- Improves surface finish and gloss of films
- Increases productivity and requires less die cleaning time
- Reduces pressure and motor torque which helps in energy savings
- Reduces melt fracture (sharkskin) and die line
- Promotes gel formation, giving clear film running
- Effective at low addition level
- Low die build-up in sheet and profile extrusion
- Reduces weld line problems
- Improves colour change time
- Tailor-made grades
Applications
- Multilayer blow film and bottles
- Cast film
- Sheet and profile extrusion
- Ropes and filaments
