Customer Question

I am using butyl rubber to make tire tubes. How can I make the tube puncture resistant? Is it possible by covulcanizing with SBR or similar rubbers? Or is there any other way?

HI. I don't think it would be possible chemically. It is usually just used for the inner of the tire and additional layer are put on it for protection. You could try a mecanical mix of kevlar fiber layer inside the butyl rubber (but that reduce the elastic propriety proportionally to the amount added).
