1. What is PVC?

PVC material is polyvinyl chloride, PVC is a plastic product synthesized from 43% oil and 57% salt. It is one of the largest plastic products in the world, and it is inexpensive and widely used.

Compared with other types of plastic products, PVC is more effective in the application of raw materials, reducing fuel consumption.

At the same time, the energy consumption of the PVC manufacturing industry is also very low. And in the later stages of the use of PVC products, it can be recycled and converted into other new products or incinerated to obtain energy. The polyvinyl chloride resin is a white or light yellow powder and cannot be used alone and must be modified.

2. What are the characteristics of PVC?

Excellent mechanical properties, excellent electrical properties, strong acid and alkali resistance, good chemical stability, but low softening point. Suitable for making thin plates, wire and cable insulation, seals, electric line pipes, Pvc pipes for water supply and drainage, etc.

Injection molding characteristics
1. Amorphous material, low moisture absorption, poor fluidity. In order to improve fluidity and prevent air bubbles, the plastic can be pre-dried. The mold casting system should be short and thick, the gate section should be large, and there should be no dead angle. The mold must be cooled and the surface should be chrome-plated.
2. Due to its corrosive characteristics, it is best to use special equipment and molds. All products must be added with different types and amounts of additives as needed.
3. It is easy to decompose. It is more easily decomposed with steel and copper at 200 °C. It will escape corrosion when decomposed. Irritant gas.

3. Advantages of PVC pipes fittings and pipes

1.Lightweight: UPVC material has a specific gravity of only 1/10 of that of cast iron, which is easy to transport and reduce costs.
2.Superior chemical resistance: UPVC has excellent acid and alkali resistance, except for the strong acid-base or strong Oxidising agents maximum.
3.Non-conductive: UPVC materials are not conductive, and are not subject to electrolysis or current corrosion, so no secondary processing is required.
Can not burn, does not support combustion, no fire concerns.
4. Easy installation and low cost: cutting and connecting are very simple. The practice of using PVC glue connection proves reliable and safe, easy to operate and low in cost.
5. Durable: It has excellent weather resistance and cannot be corroded by bacteria and fungi.
6. The resistance is small and the flow rate is high: the inner wall is smooth, the fluid fluidity loss is small, and the dirt is not easily attached to the smooth pipe wall, the maintenance is relatively simple, and the maintenance cost is low.

7.PVC pipes can be used for domestic water supply and drainage.
