Polyvinylidene fluoride shows a higher tensile strength, pressure resistance and dimensional stability than the related PTFE, but friction and insulation properties are lower. Kynar has a high mechanical strength and toughness at lower temperature and it’s self-extinguishing. The temperature ranges from -22 °F to +300 °F. Kynar shows a high resistance to chlorine, bromine and high-energy radiation.
- high tensile strength
- high mechanical strength
- high rigidity (also at low temperature)
- high chemical resistance
- very low water absorption
- good friction and wear and tear values
- high UV–resistance
- FDA compliant
- excellent radiation resistance
- excellent barrier properties
- relatively high coefficient of thermal expansion
- welding is preferred joining method
