How to separate hydrocarbons from polyurethane(PU) ? the hydrocarbons are naphtha, c5-c12. I got a 70% PU and 30% naphtha, viscous liquid from a paint
shop, i wanted use PU for something i want, so i just bought it thinking that i can purify it somehow by removing the naphtha, however i searched on
the web for like half an hour and did not find anything like boiling point of PU so... my plan to boil away the naphtha still not sure, i think PU
might thermally decompose but theres little info, any one have any ideas or links ?
many thanks.blogfast25 - 8-3-2013 at 06:02
Where is this naphtha supposed to be? In uncured PU component liquids? In polymerised PU? As a chain extender?
I've never heard of naphtha in a PU context.KonkreteRocketry - 8-3-2013 at 10:40
