Silicone Varnished Fibreglass Sleeving
Typical Characteristics
Silicone Varnished Fibreglass Sleeving is capable of continuous operation at
250°C and are rated as Class C materials (BS 2757-1956). They are also
capable of short term performance at temperatures up to 450°C. At these
excessive temperatures the silicone treatment will be volatilised but will not
chemically break down into an electrically conducting or carbonaceous product
and, providing the glass braid is not excessively flexed, the sleevings will
continue to provide an air gap and maintain electrical insulating properties.
The sleevings are resistant to burning.

Handling
To maintain flexibility Silicone Varnished Fibreglass Sleeving is only given
a light varnish saturation and continuous handling can produce some skin
irritation arising from the glass fibre.
