What is the difference between liquid silicone and solid silicone?    

1. Liquid silicone
Compared with solid high-temperature vulcanized silicone rubber, liquid silica gel is a liquid glue with good fluidity, fast vulcanization, safety and environmental protection, and can fully meet food-grade requirements.

2. Solid silica gel
Solid silica gel is a saturated polymer elastic material, which has the characteristics of high temperature resistance, cold resistance, solvent resistance, tear resistance, anti-sticking, electrical insulation, chemical resistance, etc., and has a wide range of applications.

The comparison of liquid silica gel and solid silica gel
1. Appearance
a. As the name implies, liquid silica gel is in a liquid state and has fluidity;
b. Solid silica gel is solid and has no fluidity.
2. Security
a. Liquid silica gel is a highly transparent and high-safety food-grade material, no auxiliary materials such as vulcanizing agents are added during molding, and it is sealed and charged for molding;
b. Solid silica gel is a transparent and environmentally friendly material. It needs to add a vulcanizing agent for vulcanization and molding time during molding, and open the mold for feeding molding.

3. Forming method
a. 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 (does not require manual processes such as batching, rubber mixing, cutting, and placing in the high-temperature glue process, only one worker can take the product), and the product accuracy is high (all manual procedures before molding All are replaced by machines), high output (A/B glue is mixed in a few seconds at a certain temperature), labor saving, power saving, material saving and many other advantages, it can produce all products produced by high temperature glue.
b. Solid silica gel molding is that the raw materials are solid pieces. After mixing by the mixer, the cutting machine cuts the product into the appropriate size and thickness of the mold, 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.
