The difference between liquid mold silicone and solid silicone

What is the difference between liquid mold silicone and solid silicone?

Most of the products of the silicone products factory can be made of liquid mold silicone or solid silicone. What is the difference between the two silicones? Which product is more dominant? The following are the performance references of liquid mold silicone and solid silicone

1. Shape of liquid mold silicone and solid:

(1) Liquid mold silicone is in a liquid state and has fluidity.

(2) Solid silica gel is solid and has no fluidity

      2. The safety of solid silicone and liquid silicone:

     (1) Liquid mold silicone is a high-transparency and high-safety material. No auxiliary materials such as vulcanizing agents are added during molding, and the molding is sealed and fed.

     (2) Solid silica gel is a transparent material. When molding, it is necessary to add a vulcanizing agent to speed up the vulcanization molding time. Open mold feeding molding,

3. Molding methods of liquid mold silicone and solid silicone:

     (1) Liquid silicone rubber 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 (no manual processes such as ingredients, rubber mixing, material cutting, and placement in the high-temperature rubber process, only one worker can take the product), and the product has high precision (all manual procedures before molding All are replaced by machines), high output (A/B glue is mixed at a certain temperature for a few seconds), saving labor, saving electricity, saving materials and many other advantages, and can produce all products produced by high temperature glue! It is the mainstream of the development of silicone rubber materials in the next few years.

     (2) Solid silica gel molding is that the raw material is solid in pieces. After kneading by the mixer, the cutting machine cuts the product and the appropriate size and thickness of the mold, and then puts it into the mold, and molds it at a certain temperature under the pressure molding machine. When demoulding, it is similar to plastic products, and the mold needs to be cleaned.
