Performance 1. Soft PVC containing plasticizers are generally 30-50%. Because of their softness, high strength; with good air tightness and impermeability. 2. Rigid PVC only a small amount of a plasticizer. It features hard, high mechanical strength, good chemical resistance. . 3. PVC poor heat resistance, strength affected by temperature, -20 ℃ 20 ℃, when the intensity ratio dropped to 80%. Thus, the film is not easy to keep products at a low temperature; soft products temperature does not exceed 45 ℃, hard products does not exceed 60 ℃, will be long-term aging embrittlement light. 4. PVC film in the processing, in order to prevent thermal decomposition, thermal stabilizers to be added, pvc plate, since the heat stabilizers containing lead salt, so that toxic PVC, it can not be used as food packaging. 5. PVC pest control agent in contact with the organic solvent and naphthalene, etc., will produce sticky, melting phenomenon, and easy to absorb odors; the more volatile plasticizer, Erdos pvc sheet, it should not be stored too long. PROPERTIES OF PVC has abundant raw materials (oil, limestone, coke, salt and natural gas), manufacturing processes mature, inexpensive, versatile, and other prominent features, has become second only to polyethylene resin in the world's second largest general-purpose resins , accounting for 29% of the world's total consumption of synthetic resin. PVC is easy to process, can be processed by extrusion, lamination, injection molding, extrusion, calendering, blow and other means. PVC is mainly used for the production of artificial leather, film, cable sheathing and other soft plastic products, also produces lumber, doors, windows, pipes and valves, and other hard plastic products. PVC has flame retardant (flame retardant is more than 40), high chemical resistance (resistance to concentrated hydrochloric acid concentration of 90% sulfuric acid, nitric acid concentration of 60% and a concentration of 20% sodium hydroxide), the mechanical strength and good electrical insulation advantages. But its poor heat resistance, Ganzhou pvc sheet, a softening point of 80 ℃, at 130 ℃ begins to decompose color, and precipitated HCI.
