Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin It has poor stability to light and heat. It will change color above 100°C or after prolonged sunlight exposure. It is very hard and has poor solubility. It can only be dissolved in a few solvents such as cyclohexanone, dichloroethane and tetrahydrofuran. Organic and inorganic acids, alkalis, and salts are stable, and the chemical stability decreases with the increase of temperature •Packing quantity: 25KG bag 17 tons/20' 26 tons/40' use • It is the world's largest production of general-purpose plastics and is widely used. According to the content of residual vinyl chloride monomer (VCM) in polyvinyl chloride resin, it can be divided into three types: industrial grade, food sanitary grade, and medical grade. •In construction materials, UPVC pipes, UPVC pipe fittings, profiled materials, furniture, decorative materials, floor leather, floor tiles, packaging materials, packaging films, industrial products, daily necessities, artificial leather, anticorrosive coatings, electronic equipment wires, cables, tapes, bolts , Electrical components, etc., plastic bottles, foaming materials, sealing materials, fibers, auxiliary medical supplies, gloves, and some food wrappers are widely used. • Choose SG5 for rigid PVC pipes and profiles, generally choose SG8 for injection molding products, and generally choose SG4 or below for soft PVC products
