In daily life, what we call silica gel has two physical states, namely flowing liquid and solid; liquid silica gel can flow like water, and has a certain viscosity, the density is larger than that of water, but the fluidity It is not as strong as water; liquid silica gel will undergo a curing reaction after encountering a curing agent or catalyst, and will be cured into solid silica gel with different hardness and different properties according to the type of liquid silica gel.
Liquid silica gel can be divided into:
1. Mold silicone
Mold liquid silicone is a new type of molding material. Compared with steel molds, silicone molds made of mold silicone have huge advantages in production efficiency and production cost. Today, mold silicone has been widely used in the toy and gift industry, character reproduction, architectural decoration and decoration industry, and unsaturated resin handicraft industry.

2. Pad printing silicone
Pad printing liquid silicone is used to make pad printing heads, mainly used for printing plastic toys, electroplating products, electronic toys, trademarks, and irregular patterns. The pad printing rubber head is to use the pattern on the steel plate as a carrier through the rubber head, and then transfer the pattern on the steel plate to the toy product. Pad printing liquid silicone can control the hardness by adding silicone oil.

3. Electronic potting silicone
Electronic potting liquid silicone is mainly used for the potting of electronic products. The use of electronic potting liquid silicone can seal, waterproof, dustproof, thermally conduct, shockproof and insulate electronic products. In addition, one is a potting compound for LEDs, which has the characteristics of high transparency and high refractive index.

4, hand board silicone
Prototype liquid silicone is also called the first version of silicone, which is usually used to make prototypes. Compared with the prototype, the liquid silicone has the characteristics of wear resistance and strong resilience after curing.

5. Silicone glue
Silicone glue is what we usually call glass glue, which is also a kind of liquid silica gel. In the process of using silicone glue, the curing agent is added disorderly, and when it encounters water molecules in the air, it can be cured into a tough solid, so as to achieve the adhesion between the glass gaps. The cured silicone adhesive has the characteristics of weather resistance, vibration resistance, moisture resistance, odor resistance and adaptability to large changes in cold and heat.

6, clothing label silicone
After the liquid clothing label silicone is cured, it is the silicone label that we often see clothing manufacturers. The use of liquid silicone to make clothing signs has the characteristics of good hand feeling, wear resistance and high production efficiency.

7. High temperature silica gel
Ordinary high-temperature mold silicone used to make silicone molds can withstand high temperatures between 200 and 300 degrees Celsius, while high-temperature liquid silicone used in aviation and bronzing industries can work for a long time at 400 to 1300 degrees Celsius after curing. A change in performance occurs.

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