PPA Masterbatch
Process aid eliminate melt facture at given shear rate to allow for higher throughput before onset begins again. It is a Fluoro Polymer based processing additive Melt facture.
Melt facture is a surface roughness on films or other extruded shapes resulting from a slip/stick action on molten polymer exiting a die. It is most often seen with tougher resin such as LLDPE & HDPE. Also known as Sharkskin, Orange peel, Wavy zigzag.
Key Characteristics
- Its incompatible with PO also act as lubricant.
- Improve Polymer flow in extrusion.
- Improve productivity.
- Reduces back pressure.
- No die buildup and die lines.
- No gel formation.
- Reduces back pressure.
- Improves surface finish and gloss.
- Quicker color changeover & reduces machine startup time.
- Power consumption effectively reduces.
