The silicone rubber Siccet cables offer prolonged hot air resistance up to a temperature of 180-200 °C and a high flexibility even at low temperatures (-40 °C). The applications are countless such as the temperature sensors in autoclaves or industrial environments where the cable is subjected to continuous static curves and bends.
Key properties:
- Resistance to high temperature
- High flexibility even at low temperatures
A higher operating temperature can be reached through a special silicone rubber compound that has good mechanical properties up to 250 °C for several thousands of hours (for short periods of time it sustains temperatures of about 300 °C).
Insulated cables are not generally recommended for applications exposed to superheated steam (at temperatures above 130 °C).
Flexibility at low temperatures
Silicone rubber insulated cables maintain good electrical and mechanical properties and flexibility even at temperatures of -40 °C.
Resistance to chemical substances
Silicone rubber has good resistance to lubricating oils, but is severely damaged by alkalis, liquid fuel, chlorinated hydrocarbons, esters, ketones, and ethers. It dilates more so when in contact with naphthenic oils, while aromatic base oils, especially at temperatures above 140 °C, usually make it unusable.
Performance with flame and fire
Silicone rubber cables are flame retardant when exposed to fire. If a silicone rubber insulated cable is attacked by flames, the sheath and insulation crystallize, maintaining their properties for sufficient time to allow the intervention of safety measures. Siccet also uses special compounds which further increase the LOI value by 25%.
Stretch resistance
For applications where the cable is subject to stretching, Siccet offers more efficient solutions with silicone anti-tear sheaths obtained with special compounds.
