The consistency between dimethyl ether and rubber diaphragm in bottled LPG regulator is studied. The swelling phenomenon of rubber diaphragm is observed when it is immersed in liquid dime- thyl ether,and the performance tests such as tensile strength,elongation at break,hardness and thermal aging are carried out. The chemical mechanism of swelling and performance change of rubber diaphragm in dimethyl ether is analyzed. The possible influence of dimethyl ether as city gas on bottled LPG regula- tor used currently is discussed.
