1. Soft PVC: Containing softener is easy to become brittle and difficult to store, so its use range is limited. The soft pvc commonly used in pvc pipe fittings wholesale is generally used for floors, ceilings and leather surfaces.

2. Rigid pvc: also known as UPVC, or PVC-U products. Rigid PVC does not contain softeners, so it has good flexibility, easy forming, not brittle, non-toxic and pollution-free, and has a long storage time, so it has great development and application value. It has a wide range of applications: pipeline industry, water supply and drainage, flame-retardant electrical cable casing, electrical appliances, flame-retardant switch housings, sockets, profiles, plastic steel, partial fenders, bumpers, etc.

Compared with Kimura and steel, PVC has the advantages of high elasticity, high cold resistance, high abrasion resistance, and good finish. Therefore, the proportion of PVC applications in the world is roughly: 65% for construction plastics, 8% for packaging, 7% for electrical and electronics, and furniture And decoration accounted for 5%, general consumption 4%, and other 11%. PVC rigid polyvinyl chloride pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc., and then extruded by hot pressing. It has strong corrosion resistance, easy to bond, low price and hard texture. The PVC monomer and additives seep out, and it is only suitable for the water supply system whose conveying temperature does not exceed 45℃.

Due to its high chemical stability, it can be used to make anti-corrosion pipelines, pipe fittings, oil pipelines, centrifugal pumps and blowers, etc. Polyvinyl chloride hard boards are widely used in the chemical industry to make linings for various storage tanks, corrugated boards for buildings, door and window structures, wall decorations and other construction materials. Due to its excellent electrical insulation performance, it can be used to manufacture plugs, sockets, switches and cables in the electrical and electronic industries.
