一. The difference in appearance:

The two can be seen the appearance, one is solid the other is liquid.

1. Liquid silica gel is in a liquid state has fluidity. Generally, it is milky white translucent by default. It is divided into single-component two-component. The single-component can be formed by direct contact with air moisture; the two-component requires liquid silica gel It can be vulcanized molded by performing quantitative ratio mixing stirring with the curing agent.

2. Solid silica gel is in a solid state has no fluidity. Generally, it is mostly white, there are many molding methods. The specific needs are determined according to the purpose.

二. The difference in the field of use:

1. Liquid silicone is generally used in baby products, kitchen products medical products, it can directly contact food human body.

2. Solid silicone is generally used in daily necessities, industrial miscellaneous parts, auto parts.

3. The safety of liquid silicone solid silicone: Liquid silicone is a highly transparent safe food-grade material. No auxiliary materials such as vulcanizing agent are added during molding, it is sealed fed. Solid silica gel is a transparent material. A vulcanizing agent needs to be added during molding to speed up the vulcanization molding time.

三, the difference between silicone molding methods:

Liquid silicone molding methods commonly include manual molding injection molding. The two operation modes are roughly the same, but the difference lies in the vacuuming link. Manual operation needs to use a vacuum machine to remove bubbles vacuum, the injection molding silica gel of the machine operation is performed in a vacuum environment, so there is no need to vacuum remove bubbles.

        Solid silica gel is usually molded by compression molding. The solid silica gel is cut into a suitable amount of silica gel then pressed on a mold at a high temperature.
