ROHACELL bodies RF-89
Rohacell synthetic This is a PMI foam which is normally used in aerospace and radar technology. In my opinion this foam is the best synthetic to use when creating float bodies. It is as light as balsa but much harder and also it's water resistant because of the 'closed cell' structure. Comparing to other foams, Rohacell is also better chemical resistant. Even superglue can be applied to it.
