The PVDF line consists of a comprehensive range of pipes, fittings and manual valves for use in the construction of process and service lines for conveying pressurised industrial fluids in a temperature range from -40° C to 140° C.
The FIP PVDF line uses Solef® PVDF resins, manufactured by SOLVAY for industrial applications, for the production of pipes, fittings and valves made by extrusion and injection moulding. The entire line is made using Solef® resins by SOLVAY S.A. classified according to ASTM D 3222 and complying with the requirements of ISO 10931.
Thanks to its high purity and exceptional performance, PVDF is the best alternative to metal materials, and is extensively used in industrial applications (chemical, oil, pharmaceutical, pulp and paper, electronic, etc.), whether in process systems or otherwise.
PVDF MAIN PROPERTIES AND CHARACTERISTICS:
- Excellent chemical resistance: the use of Solef® resin, a vinylidene fluoride polymer, ensures excellent resistance to corrosion and abrasion when conveying highly aggressive chemicals. PVDF is basically inert to most inorganic acids and bases, organic acids, aromatic and aliphatic hydrocarbons, alcohols and halogenated solvents. However, it is not recommended for use with fluorine, amines, ketones and oleum (sulfuric acid with sulfur trioxide).
- Excellent thermal stability: PVDF maintains its characteristics unchanged in a temperature range between -40° C and +140° C. PVDF pipes are particularly suitable in all applications requiring high operating temperatures, very low levels of fluid contamination and high resistance to ageing due to atmospheric agents and UV radiation. The material’s excellent mechanical properties are retained even at high temperatures.
- Fire resistance: Solef® resins guarantee excellent fire resistance without the need for flame retardants (Limit Oxygen Index, LOI = 44%). In case of combustion, smoke emissions are moderated. Solef® PVDF resins are classified UL-94, class V-O.
- Purity: Solef® PVDF resin is an extremely pure polymer that does not contain stabilizers, plasticizers, lubricants or flame retardants. As a result, it is the ideal material for conveying ultra-pure water and chemicals, ensuring the non-contamination of the conveyed fluid. As it is physiologically non-toxic, it is suitable for conveying fluids and food products.
- High abrasion resistance: according to the Taber Abrasion Test (in which the weight loss of a material is measured after being exposed to an abrasive wheel for 1000 cycles), PVDF is the most resistant thermoplastic material (CS-10 Load 1kg – Weight Loss / 1000 cycles = 5-10 mg.)
