PVDF tube

PVDF tube (polyvinylidene fluoride tube), closely arranged between molecular chains, strong hydrogen bonds, natural flame resistance, crystallinity of 65% ~ 78%, long-term use temperature -40~150 ℃. Its outstanding features are high mechanical strength, good radiation resistance, and can be used outdoors for a long time without maintenance. It has good chemical stability and is not corroded by acid, alkali, strong oxidant and halogen at room temperature. It is widely used in petrochemical, electronic and electrical, steel pickling, and acid-base transportation.

PVDF tube features:

1 very good chemical resistance, at room temperature is not acid, alkali strong oxidant, halogen corrosion.

2 high impact strength, wear resistance, creep resistance, high mechanical strength and good toughness.

3 good heat resistance, non-flammable, long-term use temperature -40~150 ℃, and high dielectric strength.

4 with outstanding weather resistance, ozone resistance, resistance to ultraviolet and nuclear rays.
