RPVC， CPVC， UPVC Screw Barrel

We usually refer to rigid PVC when discussing PVC products; there are many other common categories of rigid PVC, including UPVC, CPVC, WPC, SPC, etc.

Rigid PVC contains no softener, so it is flexible, easy to shape, non-brittle, non-toxic, non-polluting, long-lasting, and has excellent value for development and application.

Over 90% of PVC production today uses counter-rotating inward twin screw barrel (conical and parallel).

Features

1. To prevent overheating, the screw design should be as low shear as possible.

2. Screws and barrels are practical anti-corrosion and anti-wear solutions.

3. The screw has a self-regulating closed temperature system without oil, which provides precise temperature control and easy maintenance.

4. High compatibility. For rigid and semi-rigid PVC extruders, we offer a wide variety of RPVC, CPVC, UPVC screw barrel models and designs. Depending on the region and country, we have fine-tuned rigid PVC screw barrel designs, and we also offer standard and high speed twin screw models. >>Contact us to learn more about your new screw barrel.
