Application :

Closed cell sponge neoprene rubber profile offer moderate resistance to oils and gasoline. Neoprene features good flame resistance, weathers well, and has very good resistance to abrasion, flex cracking, alkalis and acids.

However, expect poor resistance to aromatic and oxygenated solvents and limited flexibility at low temperatures. Neoprene rubber profile are generally considered an excellent all-purpose solution with a solid balance of properties and few limitations.
