Fabric Backed PVDF Sheet (PVDF-SK)

PVDF glass fiber backed sheet is hot-pressed composite of anti-corrosion PVDF facing and glass fiber reinforced base. Premium lining for chemical anti-corrosion, environmental facilities and hydrometallurgy.

It combines PVDF’s superior chemical resistance with high tensile strength of fiberglass, eliminating delamination, bulging, leakage and poor strength of ordinary plastic lining. Ideal for long-term service of extraction tanks, reactors, acid & alkali tanks and pickling vessels.

Core Performance Advantages 

 1.Superior Chemical Resistance for Severe Corrosive Conditions Resist long-term immersion of pH 1–14 strong acids & alkalis, strong oxidants (nitric acid, hydrogen peroxide) and organic extractants (P204, P507) without swelling, degradation or permeation. Working temperature: -40℃~125℃, no deformation or peeling under high temperature, outperforming PP, PE and standard PVDF sheets. 

 2. Fiberglass Reinforcement for Enhanced Structural Strength Fiberglass substrate greatly improves rigidity, impact resistance and anti-creep property with tensile strength raised by 200%–400%. Resist liquid erosion, mechanical vibration and heavy load, no cracking, deformation or embrittlement during long service. 

 3. Stable Composite Structure to Avoid Leakage & Delamination Patented hot-press bonding with peel strength ≥6N/cm, much higher than regular PVDF. Hot-air fusion welding enables seamless integral joint equal to base material, eliminating medium leakage, lining bulging and delamination. 

 4. High Purity Without Medium Contamination Made of virgin imported PVDF resin with no impurity or heavy metal precipitation, suitable for production & storage of high-purity rare earth, nickel-cobalt-lithium and pharmaceutical intermediates to guarantee material purity and extraction efficiency. 

 5. Low Surface Adhesion for Easy Maintenance & Cost Saving Low surface energy prevents scaling and material adhesion to cut cleaning cost. On-site cutting, welding and partial repair available instead of full lining replacement, lowering maintenance expense by over 50%. 

 6. Insulative & Flame Retardant for Safe Operation Excellent electrical insulation and high breakdown voltage; UL94 V-0 flame retardant (self-extinguishing after flame removal), compliant with explosion-proof chemical and high-purity semiconductor working conditions.
