PVC pipe: low molecular weight soluble in ketones, esters and chlorinated hydrocarbons and other solvents. High molecular weight insoluble. PVC resin is obtained by molding PVC. Its low cost of monomer, mature production technology, easy processing. Acid and alkali resistance, abrasion resistance, electrical insulation, does not burn; but poor thermal stability and lightfastness. 140 ℃ decompose and release hydrogen chloride, in the molding process, the need to add a stabilizer. Softening temperature is low, limit below 80 ℃ use. Depending on how much the addition of a plasticizer can be prepared soft plastic and hard resin. Soft plastic can be used as wire and cable sheathing and other insulating materials, it can be made transparent film used as a raincoat, tablecloth, agricultural film and other seedlings; also used for making leather, foam and polyvinyl chloride fibers. Hard plastic can be used for making sheet metal, pipes, tanks, absorption tower. By suspension polymerization of vinyl chloride can be obtained powdered resin, if the emulsion polymerization method, we can get a paste resin. Pneumatic tubes using tips: Polyurethane pneumatic hoses for compressed air, general industrial water insulating sleeve, non-corrosive oil. To maintain the long life of pfa insulating sleeve, will face used on the rated working pressure and ambient temperature. As the temperature rises insulating sleeve, working pressure should be reduced, if it exceeds the limit, the hose may be broken. Fluid temperature is too high or corrosive fluid chemical costs bushing pregnant may cause the hose rupture, ambient temperature is too high or workspace chemical gases may cause the hose cracking, storage in damp places or Fang deposit period is too long, will make the hose hydrolysis or aging, may lead to breakage bushing | insulating sleeve pregnant | the crown insulating sleeve (certified merchants) provided by the Dongguan City, the crown plastic products Limited.
