What is UPVC material?

19 Jun, 2024

It is called plasticizer-free polyvinyl chloride or hard PVC, and is the 1 amorphous thermoplastic resin made from vinyl chloride monomer by polymerization.
Composition: UPVC is mainly polymerized from vinyl chloride monomer, and a certain amount of additives are added, such as stabilizers, lubricants, fillers, etc. In addition, in order to improve its performance, the method of blending modification with other resins (such as CPVC, PE, ABS, EVA, MBS, etc.) is also used.
Features: High melt viscosity: UPVC has high melt viscosity and poor fluidity, which causes it to require specific conditions and technologies during processing. The molding temperature range is narrow: the molding temperature of the resin is very close to the thermal decomposition temperature, and the temperature range that can be molded is very narrow, which increases the difficulty of its processing.
Excellent chemical resistance: UPVC pipe has excellent acid, alkali and corrosion resistance, and is particularly suitable for use in the chemical industry.
Light weight: PVC pipe material is very light, convenient handling and construction, can save labor.
Good electrical insulation: PVC pipe is rich in superior electrical insulation, suitable for wire, cable conduit.
Do not affect the water quality: UPVC pipe by the dissolution test does not affect the water quality, is the ideal choice for tap water piping.
Water piping engineering: UPVC plastic pipe has the advantages of acid and alkali resistance, corrosion resistance, no rust, no scaling, and protection of water quality, and is widely used in water piping engineering.
Water-saving irrigation piping project: UPVC drip irrigation system can save water by 50%-70% compared with ordinary irrigation, while increasing crop yields.
Building piping engineering: UPVC is also commonly used in the construction of internal piping systems.
Telecommunications Engineering: Due to its excellent insulation capacity, UPVC pipe is also used as a conduit for postal and telecommunications cables.
Chemical plant: UPVC plastic pipe acid and alkali resistance, corrosion resistance, is the first choice for many chemical plant infusion piping.
