PCTFE is especially highlighted for the most excellent transmission rate and moisture-proof properties of fluoropolymers that have various excellent properties including heat resistance, chemical-resistance, non-stickiness, flame-resistance, and electrical properties. It offers superior gas barrier property to other fluoropolymers.
- It is the best moisture-proof material(water vapor transmission rate) with excellent gas transmission rate among fluoropolymers and engineering plastics.
- It is harder and more stable in size than other fluoropolymers and has impact-resistance property.
- It has excellent low-temperature property with greater mechanical strength even at low temperature. This characteristic is utilized in valve sheets for liquid helium.
