Industrial PVC scrap recycling

Why Twin Screw for PVC

PVC is a thermally sensitive material. If processing conditions are unstable, it may lead to degradation, discoloration, or performance loss.
Twin screw extrusion helps improve stability through:

Controlled shear and mixing distribution
Shorter material residence time
Efficient vacuum degassing to remove moisture and volatile gases
Stable feeding for recycled and inconsistent materials

Machine Features

Stable continuous industrial operation
High mixing efficiency for PVC compounds
Reduced risk of thermal degradation
Suitable for recycled PVC with impurities
PLC automatic control system (optional)
Wear-resistant screw and barrel design for long service life
Modular screw configuration for different formulations
