Product Introduction
PVDF (polyvinylidene fluoride) sheet is a high-performance engineering thermoplastic that combines exceptional chemical resistance, UV stability, mechanical strength, and broad temperature tolerance in a single material. With a continuous use temperature range of -40°C to 140°C and short-term capability down to -200°C, PVDF sheets outperform most common plastics - including PVC, PP, and PE - in harsh chemical environments and outdoor applications.
Available in homopolymer, copolymer, and modified grades, our PVDF sheets are supplied in plain or embossed finishes and can be easily machined, welded, thermoformed, and fabricated to meet precise design requirements. The material carries a UL 94 V-0 flammability rating, is inherently UV-resistant with no need for stabilizers, and is widely specified across chemical processing, semiconductor, architectural, aerospace, and medical industries.
Key Advantages
1. Exceptional Chemical Resistance PVDF resists virtually all inorganic acids, salts, alkalis, halogens, and aliphatic hydrocarbons at room and elevated temperatures. It is the material of choice for chemical storage tanks, piping, valve linings, and laboratory equipment where metal alloys corrode and standard plastics degrade.
2. Outstanding UV & Weather Resistance Inherently UV-stable - no stabilizers or coatings required. PVDF sheets maintain their mechanical properties and appearance after decades of outdoor exposure, making them the standard for architectural cladding, roofing membranes, and outdoor signage in aggressive climates.
3. Broad Temperature Range Performs reliably from cryogenic conditions (-200°C short-term) to continuous service at 140°C. The material retains strength and chemical resistance across the full range - far exceeding PVC, PP, and HDPE in high-temperature chemical service.
4. High Mechanical Strength Tensile strength of 50 MPa, flexural strength of 80 MPa, and excellent impact toughness (252 kJ/m²) - PVDF sheets withstand physical stress, impact, and abrasion in demanding industrial environments.
5. Excellent Electrical Insulation Volume resistivity exceeding 10¹³ Ω·cm and dielectric strength of 22 kV/mm make PVDF an effective insulator for electrical and electronic components - even in chemically aggressive or high-humidity environments.
6. Inherent Flame Retardancy UL 94 V-0 rated without halogenated additives - self-extinguishing and low smoke emission. Suitable for applications where fire safety is critical.
7. Easy Fabrication Can be machined, welded, thermoformed, injection molded, and extruded using standard thermoplastic processing equipment. Melting point around 170°C enables efficient forming and joining.
8. Low Maintenance Smooth, non-porous surface resists fouling, bacterial growth, and staining. Easy to clean, low permeability to gases and liquids, and self-lubricating for wear applications.

FAQ
1. What is PVDF and how does it compare to PTFE?
PVDF (polyvinylidene fluoride) offers higher mechanical strength and easier fabrication than PTFE, while retaining excellent chemical resistance and UV stability. PTFE has a higher continuous use temperature (260°C vs. 140°C) and lower coefficient of friction, but is significantly more expensive and harder to process. PVDF is the practical choice for most chemical and architectural applications.
2. What is the maximum continuous use temperature?
PVDF sheets are rated for continuous use from -40°C to +140°C. Short-term exposure to temperatures as low as -200°C is acceptable.
3. Can PVDF sheets be welded?
Yes. PVDF is readily weldable using hot gas, butt fusion, and extrusion welding techniques - commonly used for fabricating chemical tanks and piping systems.
4. Is PVDF FDA-compliant?
Yes. PVDF is approved for food contact applications under FDA regulations. It is commonly used in food processing equipment.
5. What chemicals can attack PVDF?
PVDF is resistant to most chemicals, but is attacked by hot concentrated sulfuric acid, strong alkalis at elevated temperatures, and certain polar solvents (such as acetone, DMF, and NMP). Contact us with your specific chemical exposure for a compatibility assessment.
6. Is PVDF recyclable?
PVDF is a thermoplastic and can be reprocessed through standard regrind and remelting methods. However, recycling infrastructure for fluoropolymers is limited.
7. What sheet sizes and thicknesses are available?
Custom sizes and thicknesses are available. Contact us with your requirements.
