Distinguished by appearance
Liquid silica gel is in a liquid state and has fluidity; solid silica gel is in a solid state and has no fluidity.

Distinguished by field of use
1. Liquid silicone is generally used in baby products, kitchen supplies and medical supplies, and can directly come into contact with food and the human body.
2. Solid silicone is generally used in daily necessities, industrial miscellaneous parts, and auto parts.
3. Safety of liquid silicone and solid silicone: Liquid silicone is a highly transparent and safe food-grade material. No auxiliary materials such as vulcanizing agents are added during molding, and the materials are sealed and fed into the molding. Solid silicone is a transparent material. When molding, a vulcanizing agent needs to be added to speed up the vulcanization molding time, and the mold is fed into the open mold for molding.

Distinguished by molding method
1. Liquid silicone is injection molded liquid silicone rubber (LSR): its full name is injection molded liquid silicone rubber, and the vulcanization equipment is an injection molding machine. The injection molding machine has a very simple process flow, high product accuracy, high output (A/B glue is mixed at a certain temperature and molded in a few seconds), saves manpower, electricity, materials and many other advantages, and can produce all high-temperature glue production products; will be the mainstream in the development of silicone rubber materials in the coming years.
2. Solid silicone molding is when the raw materials are solid pieces. After being mixed by the mixer, the cutting machine cuts the product into the appropriate size and thickness for the mold, and then puts it into the mold. The pressure molding machine presses and molds at a certain temperature. When demoulding is similar to plastic products, the mold also needs to be cleaned.

Distinguish from finished products
Liquid silicone has high transparency, no peculiar smell, and the product has a glue injection port;
Solid silicone has a transparent base and contains vulcanizing agent or other scents that cover the vulcanizing agent. The product has no glue injection port.
