It is not difficult to find, now the use of silicone or PVC soft rubber materials on the market countless products, because products have similarities, so many fake number of people. But there is a big difference between silicone and PVC.

The main differences between silicone and PVC are as follows:

1. PVC products are made by mixing polyvinyl chloride with oil and creams, and the raw materials are cooled using a micro-injection process. And silica gel, just use silica gel color paste, etc. to chemical element by the rubber mixing machine press deployment, placed in the mold by the oil press heating cooling molding.

2. From the appearance, PVC products relative to silicone products show rough, silicone products smooth surface, color. 

3. According to feel judgment, silicone products soft, good toughness and elasticity, PVC soft gum relatively less hard, both soft and hardness can be adjusted, but PVC no toughness. 

4. PVC materials have common materials and environmental materials also called atbc-PVC, and silica gel can pass the ROHS certification, is environmentally friendly. 

5. Silica gel products are generally made more transparent, burning smell is relatively small, the product into powder, and PVC products with fire after the product will be black, burning smell.

6. Silica gel products in PVC products more heat and cold, silica gel products can be heated in the microwave oven, and PVC can not.

Analysis of main use and advantages of PVC material

Because of the high chemical stability, so can be used to make anticorrosive pipes, pipe fittings, pipelines, centrifugal pumps and blowers. Polyethylene Board is widely used in chemical industry to make all kinds of storage tank lining, building corrugated board, door and window structure, wall decoration and other building materials. Because the electrical insulation function is good, may in the electrical, the industry, uses in the plug, the socket, the switch as well as the electric cable. In daily life, polyethylene used for sandals, raincoats, toys and artificial leather!
