Lanphan Hypalon rubber flexible bellow also called CSM rubber flexible bellow, it's main feature that it can be used under constant 120.In the high temperature volatility medium, like 40% Chromic acid, nitric acid, 30% hydrogen peroxide, etc, the stability is higher. Hypalon rubber can be widely used for bLeaching tower storage tanks, chromic acid tank, tankers, sodium hypochlorite reaction tower and oxidation of drugs and other equipment tower.

in order to distinguish the rubber easily, some compan will add color code on the surface of rubber bellows and after vulcanization, it will be long time pasted on the surface. Hypalon's color is green, EPDM's color is red, NBR's color is yellow.

If there are two kinds of rubber, there will be two color codes.
