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.
