There are countless products of silicone and PVC soft rubber. Because the products are similar, there are many people who are indiscriminately filling the number. In fact, there is a big difference between the two.


The main differences between silicone and PVC are as follows:

1. Silica gel can pass ROHS certification and is environmentally friendly.

2. Silica gel is soft in texture and feels good, while PVC products are rough.

3. Silicone products are relatively soft, while PVC products are relatively hard.

4. Silicone products are more flexible, but PVC has no toughness.

5. Silicone products are generally made relatively transparent, while PVC products are made in solid color.

6. Silica gel products will turn white after being burned with a relatively small burning smell, and the product will become powdery, while PVC products will turn black after being burned with a fire, and the smell will be unpleasant when burned.


From the appearance of the product, PVC products are slightly rougher than silicone products. The surface of silicone products is smooth and colored. From the hand feel, the texture of silicone products is softer, with better toughness and elasticity, while PVC soft rubber is relatively hard. , But the softness and hardness of both can be adjusted. PVC materials have ordinary materials and environmentally friendly materials, also called ATBC-PVC, and silica gel itself is environmentally friendly, and the prospects of silica gel products are still quite good.
