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, since the heat stabilizer comprises lead salts, so that the PVC toxic, 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, Shanxi coal bin liner, and easy to absorb odors; as plasticizers more volatile, it should not be stored too long. Applications range from the consumption structure, Liaoning coal bin liner, currently 65% ??of the PVC product hardware products in the consumer sector (including 15% of pipes, pipe fittings 5%, 30% doors and windows and profiles, plates and sheets of 8%, etc. etc.), 35% for the production of soft products. After the proportion of hard PVC products will gradually expand the development of hardware products will be composite, blended materials and other raw materials and products to adapt to the requirements of the main building materials market. Wire and cable products is still soft, packaging materials and wallpaper based. Products to the overall development of non-toxic, low plasticizer direction. PVC market price volatility presents more cyclical and strong features, in general, the pattern is the fundamental supply and demand factors, Renhuai coal bin liner, in particular the performance of short-term cost factors, production factors, changes in inventories, changes in demand, changes in raw materials prices (electricity prices, crude salt prices, crude oil prices, the price of ethylene, VCM and EDC monomer prices, etc.), but also by the long-term impact of national policies, such as anti-dumping tariff adjustment of industrial structure, industry access, tax adjustment impact. Is the fundamental supply and demand factors that affect the price of PVC. In the long run, Heilongjiang coal bin liner, in recent years, China's PVC production capacity of sustained and rapid growth, substantial increase in production, but the PVC capacity utilization has declined, while demand growth slowed, net imports continued to decline, China is expected in the near future It will be transferred to net exporter ranks. From the evolution of domestic PVC supply and demand pattern of view, with the new capacity launched into the domestic market supply loose, overall supply and demand will be an oversupply of direction.
