Silicone rubber: Silicone rubber is prepared from dimethylsiloxane and other silicone monomers in the presence of a catalyst. Since silicone rubber has a wide temperature range and is suitable for many applications, it has developed very rapidly.
Has the following excellent performance:
1. High heat resistance and excellent cold resistance. Silicone rubber has a long-term temperature range of -90 to 250 ° C, which is the widest among all rubbers.
2, excellent electrical insulation properties. Even when the temperature and frequency change, or when it is wet, the electrical insulation properties of the silicone rubber are relatively stable; and the silica formed after combustion is still an insulator. This is very advantageous for aerospace wires. In addition, it has good resistance to corona and arc resistance.
3. Excellent resistance to ozone aging, oxygen aging, photoaging and atmospheric aging. After the rubber was placed outdoors for several years, the performance was almost unchanged.
4. It has special surface properties. In addition to hydrophobicity, it is not sticky to many materials.
5. After long-term storage, the silicone rubber has a water absorption of no more than 0.015%. It has no breeding effect on various algae and mold, and has good mildew resistance. Therefore, the wire and cable made of it is suitable for use in tropical and wet tropical environments. Different brands of silicone rubber are also flame retardant, radiation resistant and oil resistant.
6, good thermal conductivity, twice as much as ordinary rubber. This is good for increasing the current carrying capacity of wires and cables.
7. The air permeability is several tens to hundreds of times larger than that of ordinary rubber, and the permeability to different gases varies greatly.
8, odorless, non-toxic, excellent antithrombotic, biologically inert.
Among the varieties of wire and cable production, it is mainly used for TV lead wires, H-class motor lead wires, starter cable wires, marine power cables and control cables, and high-altitude aircraft wires.
