Distinguish from appearance
Liquid silicone is in a liquid state and has fluidity; Solid silica gel is solid and has no fluidity.

Distinguish from the field of use
1. Liquid silicone is generally used in baby products, kitchen supplies, and medical supplies, and can come into direct contact with food and the human body.
2. Solid silicone is generally used in daily necessities, industrial miscellaneous parts, and automotive accessories.
3. Safety of liquid silicone and solid silicone: Liquid silicone is a highly transparent and safe food grade material that does not add auxiliary materials such as vulcanizing agents during molding, and is sealed and fed for molding. Solid silicone is a transparent material that requires the addition of a vulcanizing agent to accelerate the vulcanization molding time and open mold feeding for molding.

Distinguish from the forming 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 for a few seconds to form), and multiple advantages such as saving manpower, electricity, and materials. It can produce all products produced with high-temperature glue; It will be a mainstream in the development of silicone rubber materials in the coming years.
2. Solid silicone molding is a process in which the raw material is solid blocks, which are mixed by a mixer and cut into products and molds of appropriate size and thickness by a cutting machine. Then, they are placed in the mold and molded at a certain temperature by a pressure forming machine. When demolding, it is similar to plastic products and also requires cleaning the mold.

Distinguish from finished products
Liquid silicone has high transparency and no odor, and the product has a glue injection port;
Solid silicone transparent bottom, with the fragrance of vulcanizing agent or other covering vulcanizing agents, and the product has no glue injection port.
