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.
Properties
solid,semihard,thin wall heat shrink tube.
Soft,good toughness,wear-resistance,resistant to oil solvent
Shrink temperature :125oC -150oC
Instalation temperature:175oC Heat shrink ratio :radial shrinkage ratio≥50%, Axial shrinkage≤10% 2:1
Working temperature -55℃-175℃ Standard color: Transparent , black
Special usedin terms of high temperature,rub resistance,high cut
resistance,chemical resistance,oil resistance fields etc.
Transparent PVDF heat shrink tube is very convenient for observer
to see the packed things. PVDF heat shrink tube can offer
dielectric and stress relieving for the welded point and needle
joint. It is widely used as the insulation of high temperature
components and parts . Thin wall sturcture is the ideal products
for the miniature components.

PVDF Pipe Features and Benefits:
1.Mechanical strength and toughness
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)
