Frequently asked questions about PVDF
Why PVDF instead of PP?
PVDF withstands higher temperatures (up to ~140 °C) and more aggressive media and achieves the highest purity – important for pharma, semiconductors and ultra-pure water.
Is PVDF suitable for ultra-pure water?
Yes, PVDF is physiologically safe, extremely pure and used in the semiconductor and pharmaceutical industries.
How is PVDF jointed?
By butt, socket or infrared (IR) welding – for tight, high-purity joints.
Request PVDF?
Medium, pressure, temperature, size and quantity are enough – we recommend the material and supply the complete system including fittings and welding technology.
