What material is good for plastic bellows?
In the cases to recommend the use of PE (polyethylene) bellowsNo oxidizing acids, no environmental oils, vegetable oils, mineral oils, no organic solvents such as aliphatic hydrocarbons, aromatic hydrocarbons, ketones, esters, etc..Mainly used in the temperature range of -40 to 80 degrees Celsius environment; used in automobiles, motorcycles and other motor vehicle wire harness sheath; also used for household appliances, precision machine tools and other equipment wiring wire sheath.
In the next case, it is recommended to use PA6 (nylon 6) bellowsNo sulfuric acid, formic acid, acetic acid, nitric acid, hydrochloric acid, calcium chloride, methanol and strong oxidant in the environment; in the heat dissolved in ethylene glycol, acetic acid, ethanol, propylene glycol, 1 chlorine, 5 diol, trichloroethylene, zinc chloride, methanol, phenol, cresol solvent etc..Mainly used in the temperature range of -34 to 150 DEG C in the environment; for automobiles, motorcycles and other motor vehicle sheath wire harness sheath; can also be used for household appliances, precision machine tools and other equipment for electric wire harness; have good stability of various oils of animal and plant oil and mineral; resistant to various concentrations of alkali.
In the next case, it is recommended to use PP (polypropylene) bellowsNo strong acid and high concentration of oxidant in the environment; in more than 80 degrees Celsius in the environment of soluble in benzene, toluene and other aromatic hydrocarbons and chlorinated hydrocarbons in oil absorption; for most stable, small amount of mineral oil and vegetable oil.Mainly used in the temperature range of -20 to 120 degrees Celsius environment; used in automobiles, motorcycles and other motor vehicle wire harness sheath; also used for household appliances, precision machine tools and other equipment wiring wire sheath.
