How are Silicone rubber buttons made?
Silicone rubber button or silicone keypad,High Quality Silicone Button Products are being used extensively as switch mechanisms for various function buttons,offered by China manufacturer Better Silicone.
Silicon rubber means that the main chain is made up of atoms of silicon and oxygen, and the silicon is usually rubber with two organic groups.Ordinary silicone rubber consists mainly of methyl and a small amount of vinyl chloride.The introduction of phenyl can improve the high and low temperature performance of silicone rubber, and the introduction of trifluoropropyl and cyanide can improve the resistance and oil resistance of silicone rubber.Silicone rubber good low temperature resistance, generally can still work under 55 ℃.After the introduction of phenyl, can reach to 73 ℃.Heat resistant properties of the silicone rubber is very outstanding, also can long-term work under 180 ℃, slightly higher than 200 ℃ can take several weeks or longer still resilient, instantaneous can resistance to high temperature above 300 ℃.Silicone rubber has good air permeability, and oxygen penetration is highest in synthetic polymers.In addition, the silicone rubber also has the physiological inertia, does not cause the prominent characteristic of clotting, so it is widely used in the medical field.
Silicone buttons as the name suggests is made by silica gel as the raw material of key products, silicone buttons belong to the a product range of silicone products, silicone buttons has excellent heat resistance, cold resistance, environmental resistance, electrical insulation, fatigue resistance, etc.
Silica gel (Silica gel;Silicon rubber is a highly active adsorbent material, which is a amorphous material whose chemical molecular formula is mSiO2· nH2O.Insoluble in water and any solvent, non-toxic and tasteless, chemical properties stable, except strong alkali, hydrofluoric acid not react with any material.Different types of silica gel have different microporous structures due to different manufacturing methods.Chemical components and physical structure of the silica gel, determines it has many other similar materials difficult to replace features: high adsorption properties, thermal stability, chemical stability, has high mechanical strength, etc.The size of silica gel according to its aperture is divided into: macroporous silica gel, coarse porous silica gel, type B silicone, fine porous silica gel.The silicone buttons are often used in electronic calculators, remote controls, telephones, wireless telephones, electronic toys, computer keyboards, learning machine buttons, keypad keys, and digital product keys.
The rubber industry is one of the important basic industries of the national economy.Not only does it provide an integral part of daily life for people daily, medical and so on light industry rubber products, but also to the mining, transportation, construction, machinery, electronics and other heavy industries and emerging industries to provide all kinds of rubber system production equipment or rubber parts.It can be seen that the rubber industry has a wide range of products and is very broad in the industry.
