Silicone rubber raw materials can be divided into solid silica gel and liquid silicone rubber according to physical properties.
Solid silicone rubber is mainly used for molding products. For example: silicone sleeve, silicone tableware, silicone keys, etc. Liquid silicone is mainly used for extrusion molding products, such as silicone nipple, silicone hose, etc.

Type of liquid silicone rubber:
In daily life, the silicone rubber we speak of has two physical states: flowing liquid and solid; Liquid silicone rubber can flow like water and has a certain viscosity. Its density is higher than that of water, but its fluidity is not as strong as that of water; Liquid silicone rubber will undergo curing reaction after encountering curing agent or catalyst, and will be solidified into solid silicone rubber with different hardness and performance according to different types of liquid silicone rubber; Now let's look at the types of liquid silicone rubber:

Silicone rubber can be divided into:
1. Mold silicone
Mold liquid silicone rubber is a new type of mold making material. The silicone rubber mold made of mold silicone rubber has great advantages in production efficiency and production cost compared with steel mold. Nowadays, mold silicone rubber has been widely used in toy and gift industry, character reproduction, building decoration and decoration industry, and unsaturated resin handicraft industry.

2. Pad printing silicone
The pad printing liquid silicone rubber is used for making pad printing rubber heads, mainly used for printing plastic toys, electroplating products, electronic toys, trademarks and irregular patterns. The transfer printing rubber head is to transfer the patterns on the steel plate to the toy products through the rubber head as the carrier. The hardness of pad printing liquid silicone rubber can be controlled by adding silicone oil.

3. Electronic potting silicone rubber
Electronic potting liquid silicone rubber is mainly used for potting electronic products. The use of electronic potting liquid silicone rubber can play the role of sealing, waterproof, dustproof, heat conduction, shockproof, insulation, etc. for electronic products. In addition, one is the potting adhesive for LED, which has the characteristics of high transparency and high refractive index.

4. Hand plate silicone rubber
The hand plate liquid silicone rubber also known as the first version of silicone rubber, is usually used to make hand plate models. Compared with the hand plate oil mud hand plate liquid silicone rubber after curing, it has the characteristics of wear resistance and strong resilience.

5. Silicone adhesive
Silicone glue is what we usually call glass glue, which is also a kind of liquid silicone rubber. During the use of silicone adhesive, curing agents are added in disorder, and when water molecules in the air are encountered, they can be solidified into a tough solid, thus achieving the adhesion between glass gaps. The cured silicone adhesive has the characteristics of weather resistance, vibration resistance, moisture resistance, odor resistance and adaptation to large changes in cold and heat.

6. Clothing label silicone
After the liquid clothing label is solidified, we often see the silicone label of clothing manufacturers. The use of liquid silicone rubber to make clothing signs has the characteristics of good hand feel, wear resistance, high production efficiency and so on.

7. High temperature silicone rubber
The ordinary high-temperature mold silica gel used for making silicone rubber mold can withstand high temperatures between 200 and 300 degrees Celsius, while the high-temperature liquid silicone rubber used for aviation and bronzing industries can work at 400 ℃ to 1300 ℃ for a long time without any performance change after curing.

8. Human silicone
Human body silicone: It is a kind of liquid silicone with low curing hardness, which is environmentally friendly, non-toxic and has no adverse effects on human body, so it can be implanted into the body, usually used to make artificial limbs, etc. It can also be used to simulate characters.
