Material showcased: PVDF

There are many different types of plastics, and each type offers the ideal solution for different challenges. The possibilities and applications are virtually endless. Lakwijk is here to guide you in the world of plastics. From time to time, we put a specific material in the spotlight. Today, that material is PVDF.

PVDF

PVDF stands for polyvinylidene fluoride. The material has higher tensile strength, compressive strength and dimensional stability than the related PTFE. Its friction and insulation properties are, however, lower. PVDF has high mechanical strength and toughness at low temperatures and is self-extinguishing. The service temperature range is from -30°C to +150°C. PVDF shows high resistance to chlorine, bromine and high-energy radiation.

Advantages of PVDF:

• High tensile strength

• High mechanical strength

• High stiffness (even at low temperatures)

• High chemical resistance

• Very low water absorption

• Good friction and wear properties

• Self-extinguishing

• High UV resistance

• Toxic fumes when burning

• Relatively high thermal expansion coefficient

PVDF is an excellent candidate for, among other things, gaskets, pump and seal housings, rotary discs, (check) valves, extraction centrifuges, equipment, slide rails, gears, guide rails and wheels, adapters, components in the electrical industry and medical technology, dosing stations, filter frames, flanges and cuffs, roller conveyors and adjustment clamps.
