Polyvinylidene Fluoride
What is Polyvinylidene Fluoride?
PVDF (Polyvinylidene Fluoride or Polyvinylidene Difluoride) is a high-purity thermoplastic fluoropolymer with a semi-crystalline structure. PVDF exhibits a strong combination of properties at service temperatures up to 150°C, including:
- Exceptional chemical resistance
- High mechanical strength
- Piezoelectric and pyroelectric properties
- As well as good processability
PVDF properties
PVDF is a fine electrical insulator that is both chemically and thermally resistant. The material has a high impact strength and comparable abrasion resistance to Nylons. Another significant benefit of the material is that it does not require any heat or UV stabilisers.
Common PVDF applications
PVDF is used in energy consuming industries, automotive, military aircraft and petrochemical industries require VDF-based seals, gaskets, lining etc. resistance to corrosive materials
Key features:
- Heat resistance
- High abrasion resistance
- Low permeability to most gases and liquids
- Weather resistant
- Low weight
- Mechanical strength
- Radiation resistance
- Good electrical insulator
- Resistance to chemical corrosion
- Recyclable
