opticaly transparent fluoro elastomer

[fapper]

I want a opticaly transparent,doesnt need to be perfect like glass,but it cant have yellow tint or other coloration.
It must be elastomer,it must be some kind of "fluoro" or "perfluoro" type,but it cant be fluorosilicone.It also needs to be soft as possible,idealy I would want Shore A of 40

Is there any material like that? I only found some hazy looking yellow tinted,but I want clear without tint.

Translucent rather than transparent, and bluish tint, are likely the best you're going to get, in the form of PFA.

I am no expert on this,but I think PFA is not elastomer

 

[moltenmetal]

Definitely not an elastomer. Can't think of an elastomer which would meet this requirement or even come close to it.

 

[hamph]

what about TPU?
