Romania PVC special screw
The PVC special screw solves the problems of decomposition, corrosion, and uneven plasticization in PVC processing through corrosion-resistant materials, low shear structures, and precise temperature control design. It is the core component for efficient and stable production of PVC products.
Processing materials: hard PVC (UPVC), soft PVC (SPVC), PVC pipes, profiles, plates, sheets, cable materials, etc.
Industry: Building materials (doors and windows, pipelines), packaging, wires and cables, automotive parts.

Product Description
Core advantages：
Anti degradation design: Low shear threads reduce melt temperature fluctuations and inhibit PVC decomposition.
Corrosion resistance: The bimetallic layer resists HCl corrosion and extends its lifespan.
Efficient mixing: Multiple shear zones ensure uniform dispersion of fillers (such as calcium carbonate).
Rapid exhaust: The vacuum system reduces bubbles and black spots, improving the quality of the finished product.
