Rubber that hardens when heated and softened when cold

missyminxx's Avatar

I am wondering if there is a rubber or substance that if holding hot water will harden then soften once its cold? Repeatedly. Will something like this have a shelf life if it did exist?

Sounds difficult to achieve as a material.  But I have an invention in my notes that achieves a similar effect mechanically.

the only substance I know that hardens with heat is an egg.

My major is not in psychics, but I guess the solution should be there. 

Good luck

The problem is most rubbers and polymers do the opposite after cured. They harden when cold and soften when heated (to whatever extent).

that's a hard one.

If it is friction based heat then I can see a prophylactic application for it.... That and a blue pill might get a guy arrested for assault!

Chappy stop pushing your blue pills lol

Aurora,

I been researching stretchy materials for a project of mine.

They have some new lab made hydro gels that stretch like crazy, not sure if any of those would do what you want. Good luck

You might look into SATOP for assistance.  I have no idea what their requirements are for getting accepted.  Good luck!

Hi Aurora, not exactly what you are looking for, but I just came across a product called "Sugru" It is a moldable rubber compound that holds it's rubbery shape after 24 hours...

Just thought I'd share as it appears to be an awesome resource for prototypes! : )
