What material has better performance of plastic bellows?

PE (polyethylene) bellows

No oxidizing acid, no animal, vegetable or mineral oil; In the environment without organic solvents such as aliphatic hydrocarbons, aromatic hydrocarbons, ketones and esters.

It is mainly used in the environment with the temperature range of - 40 ~ 80 ℃; Sheath for wire harness of automobile, motorcycle and other motor vehicles; It can also be used for the sheath of wire harness of household appliances, precision machine tools and other equipment.

PP (polypropylene) bellows

In the environment without strong acid and high concentration oxidant; Soluble in aromatic hydrocarbons such as benzene and toluene and chlorinated hydrocarbons at ≥ 80 ℃; It is stable for most oils and absorbs a small amount of mineral oil and vegetable oil.

It is mainly used in the environment with the temperature range of - 20 ~ 120 ℃; Sheath for wire harness of automobile, motorcycle and other motor vehicles; It can also be used for the sheath of wire harness of household appliances, precision machine tools and other equipment.

PA6 (nylon 6) bellows

In the environment without sulfuric acid, formic acid, acetic acid, nitric acid, hydrochloric acid, calcium chloride, methanol and strong oxidant; Dissolve in methanol solution of ethylene glycol, glacial acetic acid, chloroethanol, propylene glycol, 1,5 pentanediol, trichloroethylene and zinc chloride, phenol, cresol and other solvents at high temperature.

It is mainly used in the environment with the temperature range of - 34 ~ 150 ℃; Sheath for wire harness of automobile, motorcycle and other motor vehicles; It can also be used for the sheath of wire harness of household appliances, precision machine tools and other equipment; It has good stability to all kinds of animal, vegetable oil and mineral oil; Able to withstand various concentrations of alkali.
