PVDF SK sheet

Lining for Composite Tanks · Firm Bonding to FRP / Steel Shell · Direct Custom Supply from Original Manufacturer

Futegao New Materials (Wuxi) Co., Ltd. is a domestic original manufacturer specializing in PVDF SK sheets. Equipped with multiple sets of modern large compound extrusion equipment, we achieve a daily capacity of 15 tons. PVDF SK sheet is a special lining material based on high‑quality virgin PVDF resin, with a layer of polyester fabric bonded to its back side. No recycled or regrind material is used throughout production. The sheet features a dense body with firmly adhered backing fabric.

It is engineered for lining construction of steel / FRP composite storage tanks, reaction baths and pickling tanks. The polyester backing creates strong mechanical interlock and adhesion between the PVDF lining and outer FRP shell, eliminating risks of lining delamination and bulging. Full‑size customization is available for thickness, length and width. Complete documentation including ISO9001, COA and SGS reports is provided. We support worldwide export and deliver cost‑effective composite lining materials for domestic engineering firms and international traders.

I. Key Advantages

1. Polyester fabric backing for strong FRP bondingSpecial laminated polyester fabric enables resin penetration and forms mechanical interlock plus chemical adhesion. Better bonding than plain PVDF; anti‑delamination, anti‑bulging for large composite tanks and pressure vessels.

2. Superior acid resistanceInherent chemical inertness against strong acids, HF, alkalis, salts and solvents. Stable at 0–140℃; no penetration, swelling or cracking. Ideal for pickling, electroplating and chemical tanks.

3. Robust mechanical performanceDensity ＞1.75 g/cm³, yield stress ＞50 MPa, tensile modulus ＞2100 MPa. Good rigidity and anti‑creep, resistant to cold flow. High peel strength for large‑volume tanks.

4. Easy on‑site weldingSupports hot‑gas and extrusion welding with PVDF rods. Wide sheets cut joint quantity; compatible with FRP hand lay‑up for fast, reliable installation.

5. Inherent flame retardancy & weatherabilityNative UL94 V‑0, no added flame retardants. Excellent UV and heat ageing resistance, suitable for outdoor tanks.

   
   

II. Main Applications

PVDF SK sheets are engineered specifically as lining layers for composite storage tanks and troughs. Primary application scenarios are listed below:

• Linings for chemical storage tanks: PVDF corrosion‑resistant linings for steel‑lined FRP composite tanks and FRP tanks, used for storing corrosive media such as acids, alkalis, oxidants and organic solvents.

• Linings for pickling & electroplating baths: Anti‑corrosion linings for steel pickling tanks and electroplating line troughs, capable of withstanding strong acids under elevated temperatures.

• Linings for reaction & neutralization tanks: Composite linings for chemical reaction tanks, wastewater neutralization tanks and extraction columns; the backing bonds firmly with FRP shells.

• Other applications: Linings for flue‑gas desulfurization equipment and environmental wastewater treatment facilities, as well as any corrosion‑resistant structure requiring adhesive bonding between PVDF lining and FRP / steel shells.

III. Custom Service

Custom thickness, length and width. Wide‑width extrusion reduces seams. Precision cut per drawings for direct installation, no extra site work needed.
