Classification and function of liquid silicone rub...

We usually say that silicone rubber has two physical states, one is flowing liquid, the other is solid. Non solid silicone rubber that can flow like water is called liquid silicone rubber. Of course, liquid silicone rubber has a certain viscosity, which is usually higher than the density of water. Therefore, the fluidity is not as strong as water. Liquid silicone rubber will react with curing agent or catalyst. According to different types of liquid silicone rubber, it will be solidified into solid silicone rubber with different hardness and performance.   Liquid silicone rubber can be divided into three types according to their properties and uses   Mold silicone rubber Mold liquid silicone is a new type of mold making material. Compared with steel mold, silicone mold made of mold silicone has great advantages in production efficiency and production cost. Nowadays, silicone mold has been widely used in the toy and gift industry, medical, electronic, mechanical fields, character reproduction, home building decoration industry, unsaturated resin crafts industry, simulation animal and plant sculpture, Buddha carving crafts and other industries.   Pad printing silicone Pad printing liquid silicone rubber is used to make pad printing rubber head, mainly used for printing plastic toys, electroplating products, electronic toys, trademarks and irregular patterns. Pad printing rubber head is to make the pattern on the steel plate as the carrier through the rubber head, and then transfer the pattern on the steel plate to the toy products. The hardness of pad printing liquid silicone rubber can be controlled by adding silicone oil.   Electronic potting adhesive Electronic potting liquid silicone rubber is mainly used for potting of electronic products. The use of electronic potting liquid silicone rubber can play the role of sealing, waterproof, dustproof, heat conduction, shockproof, insulation and so on. In addition, one is used for LED potting adhesive, which has the characteristics of high transparency and high refractive index.   Manual mold design silicone Manual mold design liquid silicone rubber is also known as the first version of silicone rubber, which is usually used to make handboard model. Compared with handboard oil mud, handboard liquid silicone rubber has the characteristics of wear resistance and strong resilience after curing.   Label silicone glue and trademark silicone glue After the liquid clothing label silicone rubber solidifies, we often see the silicone rubber label of clothing manufacturers. Using liquid silicone rubber to make clothing label has the characteristics of good handle, wear resistance and high production efficiency.   High temperature resistance silicone rubber The common high temperature mold silicone rubber used for making silicone rubber mold can withstand high temperature between 200 ~ 300 ℃. However, it can be used in aviation, stamping and other industries. After curing, the high temperature liquid silicone rubber can work at 400 ℃ to 1300 ℃ for a long time without performance change.   Human silicone Human silicone rubber is a kind of liquid silicone rubber with low solidifying hardness. It is environmentally friendly, non-toxic and has no adverse effect on human body. Therefore, it can be implanted into human body and is usually used to make artificial limbs. It can also be used to simulate characters.
