PVDF is a high-crystal polymer, which unites superb chemical resistance with good mechanical, thermal and electric properties.
On account of its properties PVDF is widely used in various branches of industry such as petrochemical and chemical industry, food industry, paper industry, textile industry and nuclear industry. Hardness, rigidity and abrasion resistance are the most important properties of PVDF because of which it is often applied in transportation techniques, electrical engineering, laser engineering, solar installations, exhaust gas treatment, water supply systems, electronics, filters, and elements of safety equipment.
Examples of elements that can be manufactured from PVDF: agitator parts, elements of sliding container inserts, flanges, rollers, filtering sheets, seals, plugs, insulators or pipe installations.
