CPVC inherent properties of resin:
CPVC resin of polyvinyl chloride (PVC) resin-modified, promising new engineering plastics isa high performance application. The appearance of the product is white or pale yellowtasteless, odorless, nontoxic loose powder. After chlorination of PVC resin, bondirregularities increased polarity increased resin's solubility increase chemical stabilityincreases to acid, alkali, salt, antioxidant chemicals, such as tolerance increases, heatdistortion temperature and mechanical performance. Chloride concentrations increased from56.7% to 63-72%, Vicat softening temperature by more than 72-82 ° c up to 120 ° c, themaximum service temperature up to 140 ° c or more, long-term service temperature up to 95 ℃or more.
Application of CPVC resins:
1, tube/plate: CPVC is used primarily in the production tubing, hot and corrosive media, notexceeding 100 ℃ to maintain high strength, and long-term use at high pressure. CPVC is theweight of the brass 1/6, 1/5 steel, and has a very low thermal conductivity, therefore, madeof CPVC piping, light weight, good insulation properties without thermal insulation. CPVCpipe heat pipe for use as chemical plants, electroplating liquid pipeline, thermal chemicalsupply lines, chlor-alkali plant of wet chlorine gas pipelines. In addition, mainly used in the production of buried high pressure and ultra high voltage power transmission cable usingCPVC jacket tube, cold and hot water pipes and pipe fittings, pipes and other products forplaces with strict fire codes, crude oil gathering and transportation pipelines, as well as avariety of CPVC wave Board, corrugated board and synthetic resin tile and so on.
2, injection molded parts: CPVC resin production of water supply pipe, filter materials,dehydrator, can also produce electric and electronic parts. If the wire Groove, conductorlayer, switch, fuse protection cover, cable insulation materials.
3, rolled sheets: can be used to manufacture chemical, corrosion-resistant chemicalequipment, such as reactors, valves, electrolysis, etc.
4, composite materials: CPVC, and some inorganic or organic fibers that form the CPVCmaterial impact resistance performance is good, better heat resistance than other resins,composites, can be made of sheet metal, pipes, corrugated sheet, profiles, and so on.
5, modified an-VDC copolymer fibers: an-VDC copolymer fibers made of the wash dryingtemperature should not be more than 60 ℃, spinning of CPVC joined 30% an-VDC copolymer fibers, can greatly improve the heat resistance and reduce shrinkage.
6, foam: heat resistance of CPVC foam material than PVC foam materials. High temperatureshrinkage when very small, can be used as hot water pipe, steam pipe insulation materials;places the CPVC solvents can produce gas in foaming when it is heated, homogeneous, porousfoam can be gas, boiling point ℃ 50-160 hydrocarbons, ethers, aldehydes, solvent as afoaming agent.
7, CPVC thermoplastic or thermosetting plastic blends, you can significantly improve themechanical and physical properties of these materials, such as products such as heat resistance, flame retardant properties can be improved.
8, used for man-made fibres. CPVC can do after snagging nets, uniforms, industrial cloth,burning the parachute and cable jacket, etc.
9, through the improvement of the production process to produce high impact performance,better transparency of CPVC, the transparent material can be used in cars, compact discs,audio and video products.
10, CPVC/PVC alloys can be used for injection, extrusion, calendering and suppressing methodand manufacture molding, tray, fan cover, electrical parts and housings, business machinehousings, tubes, car parts and communication equipment.
