Introduction of main materials of organosilicon industry

Polysiloxane is a polysiloxane, polysiloxane, polysiloxane, polysiloxane, polysiloxane, polysiloxane, polysiloxane Organic silicon products are various, because of its unique function and wide use, it is an important chemical material indispensable to national economic life.

Silicone products can be a variety of low molecular weight, liquid can flow (monomer, oil, emulsion); Or a variety of high molecular weight elastomer (glue); But also branch structure of a variety of resins, as well as oil, rubber, resin secondary products or modification, so silicone products are a large number of silicone oil, silicone rubber, silicone resin and silane coupling agent containing a variety of groups.

Silicone products have good high and low temperature resistance, generally can work in 180℃ high temperature for a long time. Silicone materials have good low temperature resistance, generally can still work at -55℃.

Silicone waterproof sealing ring

Silicone news: silicone material has good electrical insulation performance, dielectric property does not change dramatically with temperature change; The dielectric constant does not increase with the increase of frequency. And arc resistance, corona resistance, leakage resistance; Ozone resistance, radiation resistance, weather resistance, fire resistance, so it is very widely used.

Several main materials and products of silicone industry are introduced as follows:

1. Silane coupling agent

Silane coupling agent is a kind of low molecular compounds, and one end of the silicon atom is connected with chlorine or various alkoxy groups can be hydrolyzed, hydrolyzed can be connected with inorganic substances; The other end has various functional groups that can interact with organic matter, such as amino group, vinyl group, sulfhydryl group, etc., so silane coupling agent can bridge organic matter and inorganic matter. There are nearly 100 kinds of silane coupling agents in common use.

2, the silicone oil

Silicone oil is a low molecular polysiloxane containing a single or different organic group, which can be made into a variety of viscosity. Silicone oil is a high quality water repellent material with low surface tension and large contact Angle with water. The application of organosilicone oil or its modified preparation in cosmetics is increasing rapidly in recent years. Silicone oil on the skin is not greasy, feeling smooth, comfortable, can be made into a variety of skin cream.

3, silicone rubber

According to vulcanization mechanism, silicone rubber can be divided into high temperature vulcanized silicone rubber (HTV). RTV and LSR have the properties of heat resistance, cold resistance, ozone resistance, ultraviolet resistance, atomic oxygen resistance, cosmic ray resistance, water resistance, shock resistance and other comprehensive properties.

Silicone rubber has the characteristics of physiological inertia, non-coagulation, simple disinfection and so on. It can make silicone rubber products that can be implanted into the human body and all kinds of silicone rubber catheter, intubation, hydrocephalus drainage tube, peritoneal dialysis tube, and artificial heart-lung machine blood transfusion pump tube, etc.

In addition, silicone rubber has permeability, the permeability of different gases is different. Oxygen transmittance in synthetic polymer is the highest, can be used for oxygen rich film, gas separation film.
