Plastic corrugated pipe generally have three materials: PP / PE / PA. How to choose to buy?
      Plastic corrugated pipe generally have three kinds of materials: PP / PE / PA, of which PA is relatively smooth, depending on what industry you are using, choose the appropriate corrugated pipe according to your industry needs. The threading corrugated pipe is extruded with three materials of PE, PA and PP. It can be used to protect wires and cables from mechanical damage such as cutting and cutting. It has the advantages of good flexibility, good flexibility, acid resistance and wear resistance.

      1. In the case of the following example, it is recommended to use PA6 (nylon 6) corrugated pipe in an environment free of sulfuric acid, formic acid, acetic acid, nitric acid, hydrochloric acid, calcium chloride, methanol, and strong oxidants; soluble in ethylene glycol, glacial acetic acid, Chloroethanol, propylene glycol, 1,5-pentanediol, trichloroethylene, zinc chloride in methanol, phenol, cresol and other solvents. It is mainly used in the environment with a temperature range of -34 ～ 150 ℃; used for the sheath of wire harnesses for automobiles, motorcycles and other motor vehicles; it can also be used for the sheath of wire harnesses for household appliances, precision machine tools and other equipment; Animal and vegetable oils and mineral oils have good stability; they are resistant to various concentrations of alkali.

     2. In the following cases, it is recommended to use PE (polyethylene) corrugated pipe without oxidizing acids, animals, vegetable oils, and mineral oils; in environments without organic solvents such as aliphatic hydrocarbons, aromatic hydrocarbons, ketones, and esters. . It is mainly used in the temperature range of -40 ~ 80 ℃; used in the sheath of wire harnesses of automobiles, motorcycles and other motor vehicles; also used in the sheath of wire harnesses of household appliances, precision machine tools and other equipment.

      3. In the following cases, it is recommended to use PP (polypropylene) corrugated pipe in an environment without strong acids and high concentrations of oxidants; soluble in aromatic hydrocarbons and chlorinated hydrocarbons such as benzene and toluene in an environment of ≥80 ° C; for most oils Stable, absorb a small amount of mineral oil and vegetable oil. Mainly used in the temperature range of -20 ~ 120 ℃; used in the sheath of wire harnesses of automobiles, motorcycles and other motor vehicles; also used in the sheath of wire harnesses of household appliances, precision machine tools and other equipment.

     Among the above three different types of corrugated pipe, the nylon corrugated pipe has the best performance and meets the protection requirements of various harsh environments. The flame retardant nylon corrugated pipe has better performance, but the price is a little more expensive than the PP \ PE corrugated pipe. Purchasing according to your own needs, it is not clear which plastic corrugated pipe to use. You can write to us for advice.
