Dear RE Members,

Now a days everybody is using closed cell rubber insulation for chiller.It is divided in 2 catagories--- NBR/PVC or crosslinked polyolefins.

I have used Aeroflex which is from 1st catagory.It is very costly. I want to use insulation from 2nd catagory but I read one article which stated that it is thermosetting type & hence will become hard.
When I talked to suppliers of these type of Insulations.They say it is not true.
Can anybody guide me based on his experience.

Thanks
