Silicone has two physical states: one is a flowing liquid and the other is a solid. We refer to silicone rubber, which flows visually like water, as liquid silicone rubber; Of course, liquid silicone rubber has a certain viscosity and usually has a higher density than water, so its fluidity is not as strong as water. Liquid silicone rubber undergoes a curing reaction when encountering a curing agent or catalyst. Depending on the type of liquid silicone rubber, it will solidify into solid silicone with different hardness and performance.

Liquid silicone rubber type
Liquid silicone rubber can be divided into the following 8 types based on its performance and usage:

1. Mold silicone
Liquid silicone rubber for molds is a new type of molding material, and silicone molds made from mold silicone have significant advantages in production efficiency and production cost compared to steel molds. Nowadays, mold silicone has been widely used in various industries such as toy * * industry, character reproduction, building decoration and decoration industry, unsaturated resin handicraft industry, simulated animal and plant sculpture, Buddha carving handicraft, and Boli industrial products.

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

3. Electronic sealing silicone
Electronic sealing liquid silicone rubber is mainly used for sealing electronic products. By using electronic sealing liquid silicone rubber, electronic products can be sealed, waterproof, dustproof, thermally conductive, shockproof, and insulated. In addition, one type of encapsulation adhesive is used for LEDs, which has high transparency and refractive index characteristics.

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

5. Silicone adhesive
Silicone adhesive is commonly referred to as glass adhesive, and it is also a type of liquid silicone rubber. During the use of silicone adhesive, curing agents are added in an disorderly manner, and when they encounter water molecules in the air, they can solidify into a tough solid, thereby achieving adhesion between glass gaps. The cured silicone adhesive has the characteristics of weather resistance, vibration resistance, moisture resistance, odor resistance, and adaptability to large changes in temperature and cold.

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

7. High temperature silicone
Ordinary high-temperature liquid silicone rubber can withstand high temperatures between 200 and 300 degrees Celsius when used in the production of silicone molds, while high-temperature liquid silicone rubber used in industries such as aviation and stamping can work for a long time in environments ranging from 400 ℃ to 1300 ℃ without any performance changes after curing.

8. Human silicone
Human liquid silicone rubber is a type of liquid silicone rubber with low solidification hardness, which is non-toxic and has no adverse effects on human objects. Therefore, it can be implanted into the human body and is usually used for making prostheses. It can also be used to simulate characters, etc.
