Silicone rubber is odorless and non-toxic, not afraid of high temperature and resistant to severe cold. It has good strength and elasticity at 300 degrees Celsius and minus 90 degrees Celsius. Silicone rubber also has good electrical insulation, oxygen resistance, aging resistance, light resistance, aging resistance, mildew resistance, chemical stability, etc. In recent years, the rapid development of silicone rubber has made silicone rubber widely used in the wire and cable industry.
Unique properties of silicone rubber:
Ø Excellent weather resistance, UV, O2, O3, salt spray, etc.;
Ø Low surface energy, excellent hydrophobicity and hydrophobic migration;
Ø Excellent insulation performance, stable dielectric performance in a wide range of temperature and frequency. Arc resistance and leakage resistance are very good;
Ø Good high temperature resistance, can be used continuously at 180-200℃. Although the strength of silicone rubber at room temperature is only half of that of natural rubber or some synthetic rubbers, it can still maintain a certain degree of flexibility, resilience and surface hardness in a high temperature environment above 200°C, with no obvious mechanical properties. Variety;
Ø Good elasticity, good low temperature flexibility, can be used at -50 ℃. The glass transition temperature of silicone rubber is generally -70~-50℃, and the special formula can reach -100℃, indicating its excellent low temperature performance. This is of great significance to the lines used in the aviation and aerospace industries.
Ø Good flame retardant performance, almost no toxic and harmful gases are released when burning;
Silicone is mainly used for outer wrapping and filling of cables. Silicone cables are widely used in rail transit, automobile, medical, nuclear power, construction, household appliances, electric heating, heavy industry and other fields. With the vigorous development of rail transit and new energy vehicle industries, silicone cables have been widely used.
