Welcome to inquire! Contact: Zhao Shuang. PVC (full name Polyvinylchlorid), the main component of PVC, while adding other ingredients to enhance its heat resistance, toughness, ductility. This table top layer mask is painted, the main ingredient in the middle of a polyvinyl chloride pvc pipe fittings, the lowest is coated with an adhesive backing. the nature of the application of pvc pipe PVC pipe is a vacuum plastic film for packaging pvc pipe various types of panel surface, it is also known as decorative films, with film, used in building materials, packaging, pharmaceutical and other industries. Building materials industry accounted for the largest proportion, 60 percent, followed by industry, packaging industry, there are a number of other small-scale applications. PVC pipe is divided into two kinds of PVC water supply and drainage pvc plastic pipe used in municipal water supply and drainage, water supply and drainage industry, civil drainage, irrigation, watering and other vegetation. Industrial polyvinyl chloride resin mainly amorphous structure, but it also contains some crystal regions (about 5%), no sharp melting point so polyvinyl chloride pvc pipe prices, is about 80 ℃ begins to soften, heat distortion temperature (1.82MPa under a load) of 70-71 ℃, under pressure at 150 ℃ begins to flow, and slowly release hydrogen chloride, resulting in discoloration of PVC (from yellow to red, brown, and even black). Industrial PVC weight average molecular weight in the range of 4.8-4.8 million and a corresponding number average molecular weight of 2-1.95 million. The vast majority of industrial resin weight average molecular mass of 10-20 million and the number average molecular weight in the 4.55-6.4 million. Rigid PVC (unplasticized) has good mechanical strength, weather resistance and flame resistance, can be used alone as structural materials used in chemical manufacturing pipes, sheet metal and plastic injection products. Rigid PVC can be used to enhance the material.
