Silicon, the element, is quite tough.

I've just applied a butane-propane torch to a polished silicon disc (25mm diam, 1mm thick). It withstands 900+ deg C (dull orange heat) and immediate quenching in water a few times does not shatter the disc nor mar its finish.

I suspect that the application (thickness, shape) will determine its ability to withstand heating, but 300deg C. should not be a problem for any but the most peculiar of shapes.

Regards;

Hello,

i am using the silicon rubber tuching the sides of a normal household lighting bulb at diffent watts from 40, 60 to 80 Watt.

The silicon rubber need to take the heat from that, for normal period burning time.

I dont know the temperature of the surface og the glass bulb.

regards Søren

Soren,

According to my McMaster-Carr catalog:

Ordinary silicone rubber has a maximum temperature of 260 C Translucent & transparent variety of silicone rubber have a max temp of 232 C "Reinforced silicone rubber" has a max temp of 204 C "FDA silicone rubber" and "medical grade silicone rubber" have a max temp of 260 C

All of these should be safe for light bulbs. I can hold my hand on a 75W bulb for perhaps 1/4 second before it becomes painful, and do not get any burned skin, so it seems comparable to hot tap water, between 75 to 90 C more or less.

If you insulate it with silicon rubber it could get very hot indeed.
