The difference between liquid and solid silica gel

What we usually call silica gel has two different appearances, one is fluid and liquid; the other is solid. Non-solid silica gel that flows like water is called liquid silica gel; of course, liquid silica gel has a certain viscosity and is usually denser than water. Therefore, its fluidity is not as strong as water. Today, let’s introduce the difference between liquid silica gel and solid silica gel.

Liquid silicone will undergo a curing reaction after encountering a curing agent or catalyst. Depending on the type of liquid silicone, it will be cured into solid silicone with different hardness and different properties; this is also a special place for liquid silicone.

Liquid silica gel can be roughly divided into the following types according to different properties and uses：

1. Mold silicone: Mold liquid silicone is a new type of molding material. Compared with steel molds, silicone molds made of mold silicone have huge advantages in production efficiency and production costs.

2. Pad printing silicone: Pad printing liquid silicone is used to make pad printing rubber heads, mainly used for printing plastic toys, electroplating products, electronic toys, trademarks, and irregular patterns. The hardness of pad printing liquid silicone can be controlled by adding silicone oil.

3. Electronic potting silica gel: mainly used for potting of electronic products. The use of electronic potting liquid silica gel can play a role in sealing, waterproof, dustproof, thermal conductivity, shockproof and insulation of electronic products.

4. Shouban silicone: Shouban liquid silicone is also known as the first version of silicone. It is usually used to make prototype models. Compared with Shouban mortar, the liquid silicone has the characteristics of abrasion resistance and strong resilience after curing.

5. Silicone glue: Silicone glue is what we usually call glass glue, it is also a kind of liquid silicone. Silicone glue is randomly added with a curing agent during use, and it can be cured into a tough solid when it encounters water molecules in the air, so as to achieve the adhesion between the glass gaps.

6. High-temperature silicone: ordinary high-temperature mold silicone used to make silicone molds can withstand high temperatures between 200°C and 300°C, while high-temperature liquid silicone used in aviation and bronzing industries can be cured at 400°C to 1300°C for a long time. Work without performance changes.
