Everyone knows that silica gel is divided into two categories, organic silicon and inorganic silicon:

Inorganic silica gel is a kind of highly active adsorption material, which has the characteristics that many other similar materials are difficult to replace: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc. It is used as a desiccant for household use and humidity adjustment Agent, deodorant, etc .; industrial use as oil hydrocarbon decolorizer, catalyst carrier, pressure swing adsorbent, etc .; separation and purification agent for fine chemicals, beer stabilizer, paint thickener, toothpaste friction agent, matting agent, etc.

Organic silica gel is an organosilicon compound, which refers to a compound containing Si-C bond, and at least one organic group is directly connected to the silicon atom. It is also customary to use the oxygen, sulfur, nitrogen, etc. to make the organic group and silicon Atom-linked compounds are also regarded as organosilicon compounds. Among them, polysiloxane composed of silicon-oxygen bond (-Si-O-Si-) as the skeleton is the most widely studied, most widely used and most widely used organic silicon compound, accounting for more than 90% of the total dosage .

The production process of silicone can be divided into extrusion and molding:

Extruding silicone is relatively common, for example, the sealing ring on a household rice cooker is called a silicone sealing ring for rice cookers.

Molded silicone is a bit more complicated and irregular in shape, including silicone bowls, silicone ice trays, silicone cake molds and so on.

Silicone rubber is a synthetic elastomer made of filler-reinforced cross-linked silicon-based polymer. It achieves a combination of chemical and mechanical properties unmatched by organic elastomers.

What are the advantages of this kind of material?

First: It has a longer service life in harsh environments and is not affected by the weather for a long time-rain, snow, humidity, ozone, solar ultraviolet (UV); after long-term exposure of the organic elastomer to the environment May become brittle.

Second: When exposed to severe environmental stress (heat, cold, humidity, oil, ozone, ultraviolet rays), its inherent good electrical insulation quality will not change significantly.

Third: it can maintain its natural flexibility and elasticity (compression resistance) in a wide temperature range, and improve the comfort and feeling of consumer products.

Fourth: good sealing performance.

Fifth: safety and environmental protection, widely used in food processing tools, baby products, etc.

Sixth: more choices-a wider range of hardness (from Shore A10 to 80), a wider range of color options (from transparent to bright colors).

Seventh: Wider operating temperature range-from -100oC to 316oC (-148 to 600oF); organic elastomers will soften and irreversibly deform when the temperature exceeds 100oC (212oF), and the temperature is below 25oC (-13oF ) Will become brittle.

Eighth: better liquidity-easy to manufacture and improve productivity. Silicone products are now widely used in people's lives.

China has unlimited development potential in the silicone rubber industry, and the upstream and downstream industry linkage effects of the silicone rubber industry have gradually begun to appear, and the development is very rapid. According to statistics, if the proportion of silicone rubber in China's rubber consumption is increased from the current 6.5% to 2020 33%, then the overall domestic self-sufficiency rate of China's rubber can be increased from the current about 50% to more than 80%, it can be said that the market potential is unlimited.
