Silicone rubber is widely used in the market because it does not release toxic substances, has a soft and comfortable touch, and has good physical and chemical properties at high temperature and low temperature (-60c~+300c). There are few other polymers that can match it. Strong and powerful elastomer, and better than rubber sealing, excellent electrical insulation and resistance to chemicals, fuels, oil, water, a good material to cope with adverse environments. In the industry, such as: oil seals, keyboard keys, electrical insulation materials, automobile parts, daily necessities such as: pacifiers, artificial catheters, respirators, frog mirrors, leather shoes and sneakers, food containers, etc. Silicone can distinguish between solid and liquid, The former processing method is based on hot pressing transfer, while the latter raw material is mainly injection molding. Although the liquid state has higher equipment investment and raw material cost, its production speed is fast, the degree of processing is low, and the waste is less. Silicone injection molding, in the pursuit of precision, speed, and automation in the injection molding production industry, must be a future-oriented trend.

The difference between liquid silicone and solid silicone!
It can be seen from the raw materials, one solid and one liquid. Now let's talk about the difference between the two materials:

1. Appearance of liquid silica gel and solid:
(1) As the name implies, liquid silica gel is in a liquid state and has fluidity
(2) Solid silica gel is solid and has no fluidity!

2. Application areas of liquid silica gel and solid silica gel:
(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, etc., and has a wide range of applications.

3. Safety of solid silica gel and liquid silica gel:
(1) 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.
(2) Solid silica gel is a transparent and environmentally friendly material. It is necessary to add a vulcanizing agent to speed up the vulcanization molding time during molding.

4. The molding method of liquid silica gel and solid silica gel:
(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 (no manual processes such as batching, rubber mixing, cutting, and placing in the high-temperature glue process are required, 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 mixed, molded in a few seconds at a certain temperature), labor saving, power saving, material saving and many other advantages, can produce all products produced by high temperature glue! It is a mainstream in the development of silicone rubber materials in the next few years.

(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.

5. What is the difference between liquid silicone and solid silicone products?
Liquid silica gel has high transparency, no peculiar smell, and the product has a plastic injection port.
Solid silicone transparent bottom, with vulcanizing agent or other fragrance covering the vulcanizing agent, the product has no glue injection port
