Zhang Yongze, director of the Tibet Autonomous Region Environmental Protection Bureau, said that in July 2004, Lhasa carried out a ban on "white pollution," and the use of cloth bags and paper bags to replace disposable plastic bags had achieved good results. This year's action will be extended to the entire autonomous region.
In recent years, with the development of tourism in Tibet, the number of tourists entering Tibet has increased, and many attractions have also been contaminated by plastic products. At the same time, with the increase in the resident population in various cities in Tibet, the use frequency of plastic bags has increased significantly. “White pollution†has become an important cause of environmental pollution in some parts of Tibet.
It is polyvinyl chloride (PVC) plastic with an excellent performance of the main Plasticizer.Compared with DOP, it has the advantages of heat resistance, cold resistance, low volatility, resistance to extraction, flexibility and electrical insulation.In the products show excellent durability, resistance to soapy water and low temperature flexibility.Because of its low volatility, the use of DOTP can fully meet the temperature requirements of wire and cable, can be widely used in 70 ℃ cable material (International Electrotechnical Commission IEC standards) and other soft PVC products.
Application:
DOTP addition to a large number of cable materials, PVC plasticizer, can also be used for the production of artificial leather film.In addition, has excellent compatibility, can also be used for acrylonitrile derivatives, polyvinyl butyral, nitrile rubber, nitrocellulose and other plasticizers.It can also be used in synthetic rubber plasticizers, paint additives, precision instruments, lubricants, lubricant additives, can also be used as paper softener.
