Frequently Asked Questions About PVDF
What is the difference between PVDF and Kynar®?
+PVDF (Polyvinylidene Fluoride) is the chemical name for the fluoropolymer material. Kynar® is the registered trademark brand name by Arkema (formerly DuPont). They refer to the same material - PVDF is the generic chemical name while Kynar® is the brand name. Other equivalent PVDF products with different trade names also exist from various manufacturers.
Why choose PVDF over PTFE for my application?
+PVDF offers superior mechanical strength, better processability, and UV resistance compared to PTFE, while maintaining excellent chemical resistance. PVDF is easier and more cost-effective to machine and mold. However, PTFE offers wider temperature range and ultimate chemical inertness. Choose PVDF when you need the right balance of chemical resistance, mechanical properties, weatherability, and cost-effectiveness.
What temperature range can PVDF withstand?
+PVDF can continuously operate from -20°C to +150°C (-4°F to +302°F). For short-term exposure, it can handle slightly higher temperatures. This temperature range makes it suitable for most industrial chemical processing, architectural, and water treatment applications. For applications requiring extreme cryogenic temperatures, PTFE would be more suitable.
Is PVDF safe for food contact and pharmaceutical applications?
+Yes, PVDF is FDA-approved for food contact (CFR 177.3730) and available in USP Class VI grades for pharmaceutical and medical applications. Virgin PVDF with no additives is completely inert and biocompatible. We provide all necessary certifications and compliance documentation for food-grade and pharmaceutical-grade PVDF products.
Can PVDF be welded or bonded?
+PVDF is difficult to chemically bond due to its inert surface properties. However, mechanical joining using fasteners, threading, or mechanical interlocking designs is reliable. Specialized adhesives and surface treatments are available for specific applications. Ultrasonic welding is possible for thin PVDF components. Consult our engineers for your specific joining requirements.
What is the difference between virgin PVDF and filled PVDF?
+Virgin (unfilled) PVDF offers maximum chemical resistance, transparency, and a full temperature range. Filled PVDF - such as glass-filled or carbon-filled versions - sacrifices some maximum temperature capability but gains improved mechanical strength, wear resistance, thermal conductivity, and dimensional stability. Choose virgin PVDF for maximum chemical compatibility and transparency; choose filled PVDF for applications requiring enhanced mechanical properties.
What industries use the most PVDF material?
+Major industries using PVDF include: chemical processing (piping and equipment), semiconductor manufacturing (ultra-pure systems), water treatment (membrane filtration), architectural/building (exterior coatings), lithium-ion batteries, oil and gas, pharmaceuticals, and telecommunications (cable insulation). PVDF's combination of chemical resistance, mechanical strength, UV stability, and processability makes it ideal for these demanding sectors.
