Liquid silica gel is also a kind of silica gel relative to solid silica gel, but the morphology is liquid. Liquid silica gel can be divided into liquid silicone rubber and silica sol. In general, liquid silicone refers to liquid silicone rubber. The processing performance of liquid silicone rubber is better than solid silicone rubber. Liquid silicone rubber can be divided into two categories according to the position of its functional group in the molecular structure: one is the functional group at both ends of the functional group, called "telepaural type"; The other is the active functional group with functional groups, which is randomly distributed on the main chain, which is called "functional groups in the molecular structure" and is called "non-teleclaw type liquid rubber".

What are the advantages of liquid silica gel? Liquid silica gel transparency, tear resistance, good resilience, yellowing resistance, good thermal stability, water resistance, ventilation, heat aging and weather resistance, while moderate viscosity, easy operation, high transparency, can see whether there are bubbles and other defects in the mold perfusion material, linear shrinkage ≤0.1%, replica size is accurate.

I don't know when liquid silicone phone cases became popular in the tech world. A comprehensive view of the major mobile phone manufacturers online mall, can always see the figure of silicone liquid shell. The advantages of liquid silica gel mobile phone shell are:

1. Good hand feel. It is very skin-friendly, soft and elastic to the touch.

2. Generally, the liquid silica gel with the same material as the baby pacifier is used, which is environmentally healthy and not easy to be deformed.

3. The anti-fall and anti-scratch effect of mobile phone is very good. Mobile phone shell has good liquid silicone elasticity, shock buffering effect, mobile phone is not easy to break when falling from a high place.

4. Liquid silica gel material has strong antifouling ability, slow aging speed and long service life.

As can be seen from the above points, liquid silicone phone case is worth buying.
