The main difference between liquid silica gel and solid silica gel is that one is liquid and the other is solid; but after processing the finished product, the two are not so easy to distinguish.

The difference between liquid silica gel and solid silica gel is distinguished from the appearance. Liquid silica gel is liquid and has fluidity; solid silica gel is solid and has no fluidity.

Distinguish from the field of use 1. Liquid silica gel is generally used in baby products, kitchen supplies and medical supplies, and can directly contact food and human body. 2. Solid silica gel is generally used in daily necessities, industrial miscellaneous parts and auto parts. 3. Safety of liquid silica gel and solid silica gel: Liquid silica gel is a food-grade material with high transparency and safety. No auxiliary materials such as vulcanizing agents are added during molding, and it is sealed and fed into molding. Solid silica gel is a transparent material. When molding, it is necessary to add a vulcanizing agent to speed up the vulcanization molding time, and open the mold for feeding molding.

Distinguish from the molding method 1. Liquid silicone is injection molding liquid silicone rubber (LSR): the full name is injection molding 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 in a few seconds at a certain temperature), saves people, saves electricity, saves materials and many other advantages, and can produce all high-temperature glue production. It is a mainstream in the development of silicone rubber materials in the next year. 2. Solid silica gel molding is that the raw materials are solid pieces. After mixing by the mixer, the cutting machine cuts the product and the mold into the appropriate size and thickness, and then puts it into the mold, and the pressure molding machine is pressed at a certain temperature. When demoulding is similar to plastic products, it is also necessary to clean the mold.

From the production of finished products, liquid silica gel has high transparency, no peculiar smell, and the product has a glue injection port; solid silica gel has a transparent bottom, which has the fragrance of vulcanizing agent or other covering vulcanizing agent, and the product has no glue injection port.
