PVC-U is also called UPVC, rigid polyvinyl chloride. The full English name is UnplasticizedPolyvinylChloride. Among them, Unplasticized means "unplasticized, without plasticizer". PVC-U uses PVC as the main raw material, adds necessary additives, and is produced by extrusion molding. That is, it is composed of amorphous thermoplastic resin made by polymerization of vinyl chloride monomer and certain additives (such as stabilizers, lubricants, fillers, etc.). In addition to using additives, the method of blending with other resins is also used to make it have obvious practical value. These resins are CPVC, PE, ABS, EVA, MBS and so on.
The advantages of water conservancy engineering well pipes are: high strength, high rigidity and high hardness, good electrical insulation, good chemical stability, self-extinguishing, low water absorption, easy to bond, and easy to paint. The disadvantages are: poor toughness and limited by weather conditions.
Wide range of applications, commonly used in water supply and drainage pipelines, pumps, valves, seals, bearing retainers, portable lighting shells (auto repair), brush industry, Bowden line, dental instruments, seat bars, drilling mud core sets Tube, light box cover, etc.
