Hello Group,
i like to know somthing about Silicon.

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;
-James Garry (of course, silicones would be an entirely different matter....)

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

^^^^^^silicone?

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.

dear David,
i like to make an open structure around the light bulb, i hope this is possible.
Best regards Søren M
