Because tpu is harder and more elastic than silicone, and silicone is less elastic. From the appearance, tpu can be made transparent, but silicone can't. Even if silica gel is transparent, it will look like ground glass, and it can't be completely transparent. In addition, tpu products have many grades, so the selectivity is wider, the patterns are more than silica gel, and the selection range is wider.

Silicone is mainly impact-resistant, which can reduce the damage caused by collision to mobile phones to a certain extent. But silica gel is easy to loosen, and it will be easy to loosen after a long time. In addition, silica gel looks heavy and thick, which is not conducive to the heat dissipation of mobile phones. My hands feel sticky and uncomfortable. Especially in summer.

Introduction of liquid silica gel

Liquid silica gel has excellent transparency, tear strength, resilience, yellowing resistance, thermal stability, water resistance, good air permeability, thermal aging resistance and weather resistance, and at the same time, it has moderate viscosity, easy operation, high transparency, and can see whether the castable in the mold has defects such as bubbles, the linear shrinkage is ≤0. 1%, and the size of the copied product is accurate.

Liquid silicone rubber can be used for trademarks, products, nipples, medical supplies, coating, dipping and pouring. Silica gel products, such as molding molds, injection molding processes, cake molds, etc. Used in crystal glue, polyurethane, epoxy resin, etc. It is widely used as moisture-proof, consignment and insulation coating and potting material for electronic components in the electronic industry, and plays a role in dustproof, moisture-proof, shockproof and insulation protection for electronic components and components.
