On the surface, silica gel is a porous solid silica material with a large specific area. Silica gel is an amorphous substance and is a highly active adsorbent. Compared with other similar materials, silica gel has many advantages, such as high adsorption performance and stable chemical properties.

In terms of hardness, silica gel generally has a hardness of 0A to 70A, while TPE generally has a hardness of 0A-100A, the softest can reach 000 degrees or 00000 degrees, so TPE is softer, and the shape of silicone is stronger.

Silicone has advantages over TPE in terms of high temperature resistance. The temperature resistance of silica gel is generally between 200 ° C and 300 ° C, while TPE theoretically generally has a high temperature resistance between 130-150 ° C, and it will age and crack when it is higher.
