1. Product overview:
This product is a special PVC with a degree of polymerization of 950-1100, a K value of 65-68, and the average particle diameter is usually between 20-40μm. It has a compact structure and is usually mixed with paste resin to reduce paste viscosity, improve paste processing fluidity, and improve paste product performance. In the processing of polyvinyl chloride paste, it can partially replace the paste resin to reduce the viscosity, improve the processing performance, and improve the matting performance of the product. Mainly used in artificial leather, floor leather, wallpaper, plastic toys, bottle cap pads, automotive chassis coatings and welding coatings between vehicle parts.
