PVDF tube (polyvinylidene fluoride tube) has tightly arranged molecular chains, strong hydrogen bonds, natural flame resistance, crystallinity 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 acids, alkalis, strong oxidants and halogens at room temperature. It is widely used in petrochemical, electronic and electrical, steel plant pickling, acid and alkali liquid transportation.

Features of PVDF tube:
1 Good chemical resistance, not corroded by acids, alkalis, strong oxidants, and halogens at room temperature.
2 High impact resistance, wear resistance, creep resistance, high mechanical strength and good toughness.
3 Good heat resistance, non-combustibility, long-term use temperature -40～150℃, and high dielectric strength.
4 It has outstanding weathering resistance, ozone resistance, UV resistance and nuclear radiation resistance.
Material: PVDF pipeline construction is a vinylidene fluoride homopolymer or a copolymer of vinylidene fluoride and other less-recorded fluorine-containing vinyl monomers. PVDF resin combines the characteristics of fluorine resin and general resin, in addition to good chemical resistance In addition to high temperature resistance, oxidation resistance, weather resistance, and radiation resistance, PVDF tubes also have special properties such as piezoelectricity, dielectric properties, and pyroelectric properties. They are currently the second largest among fluoroplastics. product.

At present, the materials of high-purity water and ultra-pure water transportation pipelines are all PVDF pipes. Because PVDF pipes have good chemical stability, cleanliness, smoothness and other properties, they have been widely used in the microelectronics industry and have achieved good results. Social and economic benefits.
The pvdf pipeline has good chemical stability, chemical resistance and heat stability. It can be used for a long time in the temperature range of -62℃- +150℃, and can withstand all salts, acids, alkalis, aromatics, halogens and other media except strong solvents. It is flame-retardant, fatigue-resistant, hard to break, wear-resistant, self-lubricating, and it is a good insulating material. Its mechanical strength is high: Compared with PTFE: the tensile strength is 2 times larger, and the compressive strength is 6 times larger. Wear resistance: only slightly inferior to NYLON6, UHMWPE.
When temperature and pressure exist at the same time, its performance is much better than other plastic pipes. It is mainly used for the transportation of corrosive media in the recovery and regeneration of waste acid in the smelting industry.
