The drinking water certification O-ring material has been carefully selected
The materials used for drinking water certification O-rings include nitrile rubber, carboxylic acid nitrile, fluorine rubber, ethylene propylene rubber, hydrogenated nitrile rubber, silicone rubber, neoprene rubber, fluorosilicone rubber, polyurethane, chlorohydrin rubber, butylbenzene Rubber, Butyl Rubber, Natural Rubber, Ethylene/Ethylene Propionate Rubber, Polyacrylate Rubber, Perfluoroelastomer, etc. The same kind of rubber, due to different formulations, performance indicators also have a greater change. So simply filling nitrile rubber or nitrile-40 in the material column is inaccurate. Materials used for O-rings The Ministry of Chemical Industry has special standards such as: HG/T 2579-1994, HG/T 2021-1991, HG/T 2333-1992, HG/T 3089-2001, HB 5290-1991 and others. HG/T 2579-1994 specifically removes the specific categories of materials and only gives some indications of the material's performance.
