Heat-Insulation And Flame-Resistance Silicone Rubber Sleeving
Description for High-Temperature Silicone Rubber Fiberglass
Sleeving
Silicone Rubber Sleeves are made by coating woven fiberglass with
high-performance silicone rubber, which is extremely flexible with
exceptional toughness and abrasion resistance. In addition to
having a 200°C rating, its -73°C brittle point suggests it can be
used in a wide range of applications requiring resistance to
extreme temperatures.

Features:
Thermal: acceptable for continuous service from -70°C through
200°C. Operation at temperatures up to 315°C is tolerated for short
durations.
It is resistant to moisture, corona, ozone, radiation, compression
set, fungus, most chemicals and solvents, weathering, flexure
fatigue, and heat degradation.
Application:
silicone rubber bushings are used in appliances, motors, and
generators as well as automotive, marine, and aircraft electrical
and electronic components such as transformers, coils, relays, etc.
that require a 200°C thermal rating. In addition to being ideal for
heavy-duty insulation in high-temperature environments such as
die-casting and plastic molding, Vargas Silicone Rubber Sleeves are
also suitable for extremely low-temperature environments such as
high altitude and aerospace applications.
