can you sugg. high T foam?

[levis531]

I need to replace the foam that sits between my fan and radiator, (is mainly vibration insul. I assume). There is nothing in Halfords (I even feel embarrased mentioning that I go into this quality establishment!). I have some foam for lagging copper CH pipes that I gcould use, but maybe this will melt at rad temps? The foam does burn slowly from a matchflame.

Any suggestions?

Cheers
