PVDF (polyvinylidene fluoride) is a kind of light fluoride material, with the working temperature ranging from -70 to 150 . It features superior corrosion resistance, mechanical property, electrical insulating property, low friction coefficient, weatherability, and radiation tolerance. Moreover, the tensile strength is two times higher than PTFE, the compressive strength six times higher than PTFE, and the abrasion resistance similar to nylon.

PVDF Pipe Features and Benefits:
2.Excellent chemical and weather resistance
3.Excellent UV Resistance & Radiation Resistance
4.High purity & Low permeability
5.High abrasion resistance & Corrosion resistance
Typical Applications:
Food and beverage and dairies industry:
requiring low extractable and FDA approved compounds
Ultra pure and pure water systems:
For power plant construction and for different industries (e.g. petrochemical industry)
Pharmaceutical industry:
PVDF are very pure materials for handling water and chemicals that have special purity requirement, PVDF can be repeatedly autoclaved and cleaned with 30 psi steam without changing physical properties
Chemical processing industry:
General chemical processing for corrosive chemical and higher temperature application e.g. pulp and paper industry: in handling halogens and acids
Metal preparation and Mining:
In the metals industry, a variety of acids are used to clean, treat/prepare or separate the final product. Strong acids like hydrofluoric, hydrochloric, sulfuric, nitric and chromic are all common to this industry. The concentrations of these chemicals can vary throughout the process, temperatures tend to be elevated, and mixtures of acids are common.
Water and waste water treatment plants:
for handling high concentrations of sodium hydro chlorite and membrane filtering system, used in mechanical components, fabricated vessels, tanks, pumps, valves, heat exchanger, tower packing, piping system.
Microelectronic industry and semiconductor factories
requiring very low extractable values
Display factories (LCD, TFT, LED)
Solar cell production PV
Printed circuit board production (PCB)
