What is the coefficient of thermal expansion of neoprene?

Answer 1

It looks like neoprene doesn't have such a coefficient since it is a thermoset polymer. I think any appreciable thermal expansion applies mainly to metals. If you add any large amount of heat to a thermoset, you'll just destroy it. I think for all intents and purposes, neoprene doesn't expand in heat. If you reach a point where it would matter, it's probably already fried.

Answer 2

I could not find an exact number for you, but this website can help you for sure. You may have to be more specific, as there are various types of neoprene.
