pvc divided into hard, semi-hard, soft three materials. Rigid PVC containing plasticizer is 10-25%, semi-rigid PVC of 30 to 40%, 40 to 70% of soft PVC. All PVC products must contain a certain amount of stabilizer to prevent degradation occurs during processing. Soft PVC plasticizer products that soften the polymer. Mixed plasticizer selected or the plasticizer, and ultimately to be decided by the finished product the desired performance. Most of the plasticizer to some extent, also plays a role in processing aid. Plasticizers reduce the melting temperature and the viscosity of the resin so as to prevent the resin from sticking to the metal parts processing equipment. Hardness PVC board: class product quality, color is generally gray and white, but also need to produce hard board PVC color according to the customer, bright colors, nice, product quality implementation of the GB / T4454-1996, has good chemical stability, corrosion resistance, hardness, high strength, high strength, anti-ultraviolet (anti-aging), fire retardant (self-extinguishing), reliable insulation properties, the surface is smooth, non-absorbent, deformation, easy processing characteristics. When the product is excellent thermoforming material, can replace part of the corrosion resistance of stainless steel and other synthetic materials are widely used in chemical, petroleum, electroplating, water purification equipment, environmental equipment, mining, electronics, communications and decoration industries. PVC soft plate (coil): surface gloss and soft. Brown, green, white, gray and other colors to choose from, the product of materials on the city, the production of fine, widely used. Features soft cold, wear-resistant, acid and alkali, corrosion resistance, excellent tear resistance, excellent weldability other web physical properties than rubber. Used in chemical, electroplating, electrolytic cell linings, insulation pads, train, automobile interiors and auxiliary materials.
