PROCESSING AIDS

Polymer Processing Aids (PPA) are normally used in the extrusion process.
They have the purpose of reducing friction between melting mass and metal parts, thereby facilitating the flow of the molten material.
Simultaneous use with other additives/charges/colors may reduce performance.

Melt Fracture
Processing aids increase the flow of polymers along the walls, eliminating elastic return and leading to the disappearance of the melt fracture.
Polymers thus look more polished and smoother.

Die buildup
Die buildup is the formation of encrustations on the extruder head due to the deterioration of the polymer.
The low flowing speed of polymers near the metal walls of the head causes them to remain in prolonged contact with metal.
This results in the degradation of polymers with encrustations that require downtime to clean the extruder, causing a reduction in hourly productivity and an increase in production costs.
In summary, improving die buildup means less downtime required to clean encrustations.

Main PPA benefits
Elimination of melt fracture
Increase in gloss on the finished product
Reduction in die buildup
Increase in transparency
Reduction in pressure
Optimization of production cycles
Facilitates the flow of molten material
Reduction in energy consumption

Continued use of our processing aids also reduces the cleaning time required for changing colors in the extruder.
