PVC can be divided into soft PVC and rigid PVC. Hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is commonly used on floors, ceilings and leather surfaces, but because soft PVC contains plasticizers (this is also the difference between soft PVC and rigid PVC), physical properties are poor (such as water pipes need to withstand some Some water pressure, soft PVC is not suitable for use), so its scope of use is limited. Hard PVC does not contain plasticizer, is easy to form, has good physical properties, and has great development and application value. In the production process of PVC materials, several additives such as stabilizers and plasticizers are inevitably added. PVC pipes are also non-toxic, odorless and environmentally friendly if all environmentally friendly additives are used.

The PVC pipe is composed of PVC resin, stabilizer, lubricant and the like. Through hot pressing extrusion molding, PVC pipe has strong corrosion resistance, easy adhesion, low price and hard texture, but PVC monomer and additives ooze out. It is only suitable for water supply systems where the delivery temperature does not exceed 45 °C. Materials added to PVC plastics to enhance their heat resistance, toughness and ductility. Plastic pipes are used for drainage, wastewater, chemicals, heating fluids and coolants, food, ultrapure liquids, mud, gas, compression. Air and vacuum system applications.

PVC pipe advantages

1. It has good tensile and compressive strength;

2. The fluid resistance is small;

3. Excellent corrosion resistance and chemical resistance;

4. It has good water tightness;

5. anti-bite.
