The difference and use of silicone and rubber sealing strips

Silica gel (Silica gel; Silica) alias: Silicone rubber is a highly active adsorption material, which is an amorphous substance, and its chemical formula is mSiO2·nH2O. It is insoluble in water and any solvent, non-toxic and tasteless, chemically stable, and does not react with any substances except strong alkali and hydrofluoric acid. Various types of silica gel form different microporous structures due to different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace by other similar materials: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. Silica gel is divided into: macroporous silica gel, coarse-pored silica gel, B-type silica gel, and fine-pored silica gel according to the size of its pore size.

Rubber is an elastic, insulating, impermeable and air-impermeable material made from the latex of rubber trees, rubber grass and other plants after processing. High elastic polymer compound. Divided into natural rubber and synthetic rubber. Natural rubber is made by extracting colloid from rubber trees, rubber grass and other plants after processing; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in all aspects of industry or life.

……

Generally speaking, silica gel is colorless, odorless, high temperature resistant, hygienic and safe, and can be used in medical equipment. Silica gel cannot be ignited by fire, while rubber has good extensibility, but it is not resistant to high temperature and has a heavy odor. The fire is on, and the most used should be car tires and general equipment seals, etc., but some synthetic rubbers also have special features



Rubber strip has been applied to various industries such as automobiles, doors and windows, cabinets, refrigerators, containers, etc. According to the requirements of different industries, it has successively developed unique automotive seals, mechanical seals, door and window seals It is widely used in electronic electrician, lighting, pharmaceutical, chemical, mechanical equipment, textile chemical fiber, automobile and other sealing industries.



Silicone sealing strip is used for liquid/gas sealing of various large-scale chemicals and daily necessities, which can completely isolate the contact between the carrier and the outside world, and effectively preserve the items.

1. Transportation: Application in shipbuilding industry: Marine silicone shockproof parts. Hydraulic system silicone seals, oil seals, brake caps on cars. leather bowl. hose. Foamed silicone seals, shaft seals for exhaust systems. Spark plug sleeve. ignition wire. Piston Rings. Dynamic 'O' rings for rotary engines.

2, radio, motor: telecommunications industry: TV and oscilloscope in the high-voltage cap. Silicone sealing ring and silicone insulating sleeve for AOTEMAKE potentiometer. The shell of the thyristor tube. Gaskets that come into contact with gas. insulating sleeve. Switch protective cover, electronic computer, conductive rubber sheet on telephone surface, keyboard switch, varistor, etc. Silicone sealed electrical head. Insulation of motor stator coils

3. Application in instrument and instrument industry: various silicone rubber lead wires (for capacitor radiator, coil. Transformer. Transformer. For lead wire) refrigerator defrost line. heating wire etc. Diaphragms of sensitive elements in various regulators, heating sheets for instruments, needle-resistant rubber sheets (Gaogas silicone rubber). Meter shock absorber. Silicone foam colored light cover for indicator light. Drying box. Electric stove. Far infrared heater door seal, molding. Sponge door seals (replaces toxic asbestos door seals). Boiler sealing. Seals and silicone hoses for refrigeration units.
