PVDF is resistant to solvents, most acids and alkalis, ozone and chlorine. It is also resistant to long-term exposure to ultraviolet radiation. The thermoplastic retains its properties in high vacuum and exposure to gamma radiation. However, it is unsuitable for applications that require a high coefficient of linear expansion.
This family of thermoplastics is typically characterised by:
- High continuous operating temperature (+150°C)
- Excellent thermal stability
- High impact strength
- Very good toughness
- Good resistance to wear and abrasion (similar to that of Polyamide)
- Excellent resistance to aging
- Low friction coefficient
- Low permeability to most gases and liquids
- Very low moisture absorption
- Excellent resistance to UV irradiation
- Good electrical insulation properties.
