Plastic under carburetor for heat barrier 1

[Viper488]

What type is used most often in this type of application? I think it's a phenolic plastic, but I'm seeing there's many kinds.

I want to make my own for an automotive application. Continuous use temperature would have to be high enough to endure average temperatures near an engine block.

Can such plastic in sheet from be heated and bent at angles?

Thanks

The only type of plastic I have ever seen under a carburetor, specifically as an insulation block is phenolic. It is used because it has good resistance to long term exposure to the temperatures, and also being a thermoset, it does not soften with heat.

It has excellent resistance to thermoplastic creep and fuels.

They can be made by cutting from a block of material, or by compression or even injection moulding. The filler and reinforcement packages will be different for different manufacturing processes, and the appearance of the finished part will be different.

Viper488,

Check-out this webpage.

I do not represent them.
But they do have a complete list of phenolic materials. You should be able to select the correct grade based on that information.

By the way. usually one of the best ways to cut Phenolic is with a water-Jet
