Weather resistance as well as air permeability and oil resistance of chlorobutyl rubber stopper

Weather resistance as well as air permeability and oil resistance of chlorobutyl rubber stopper

(Summary description)The weather resistance of chlorobutyl rubber stopper is closely related to the filler. Carbon black is an excellent UV-resistant compounding agent. The chlorobutyl rubber vulcanizate reinforced with carbon black has good weather resistance. Light-colored vulcanizates have poor weather resistance.

Information

Weather resistance

The weather resistance of chlorobutyl rubber stopper is closely related to the filler. Carbon black is an excellent UV-resistant compounding agent. The chlorobutyl rubber vulcanizate reinforced with carbon black has good weather resistance. Light-colored vulcanizates have poor weather resistance.

Air permeability

The air permeability of chlorobutyl rubber stopper is extremely low, about the same as that of butyl rubber. At 24°C, the air permeability of chlorobutyl rubber is only 1/9 of that of styrene-butadiene rubber and 1/4 of that of natural rubber.

Oil resistance

Chlorobutyl rubber stopper is not an oil-resistant rubber, but with proper coordination, the vulcanizate can obtain a certain oil resistance and has practical value. The more fully vulcanized, the better the oil resistance of the vulcanizate. In addition, the use of some oil-resistant rubbers in chlorobutyl rubber can also improve the oil resistance of vulcanized rubber, such as nitrile rubber and neoprene rubber.
