Omnia Plastica - Kynar - PVDF
Subcategory: Fluoropolymer; Thermoplastic; PVDF
Material Notes:
PVDF is a relatively new fluoropolymer. Like the other fluoropolymers, its best feature is its chemical resistance. The mechanical features of PVDF are notably higher than PTFE and it does not suffer strain under load.Features: - Chemical: it has the typical high chemical properties of the fluoropolymers.
- Mechanical: compared to PTFE it has higher mechanical features, such as tensile stress and compressive strength.
- Very good resistance to low and high temperatures up to 150° C. as well as UV. ray resistance.
- Excellent dimensional stability.
- Low flammability
- Low friction coefficient
- Colour: natural
Weak Point:Compared to PTFE the resistance to high temperature is lower (150 °C). Application: - Chemical: the excellent chemical resistance to acids and alkali is typical of the fluoropolymers. It is used for components in the petrochemical and chemical industries.
- Food contact: physiologically inert, it is approved for food contact by the most important international standards organisations. Thanks to this feature, it is widely used for components in food machinery, pumps for liquid food, etc.
- Electrical: very good dielectric properties, halogen-free self-extinguishing power, weatherproof: these features make PVDF increasingly indispensable in this field.
- Mechanical: thanks to the low friction coefficient, it is ideal for bearings, even when operating in water.
