Polychlorotrifluoroethylene (PCTFE)
PCTFE is a high-performance fluoropolymer featuring excellent chemical resistance, low gas permeability, good mechanical strength, and dimensional stability over a wide temperature range. It is widely used in precision sealing, chemical processing, aerospace, and electronic insulation applications.
- Density: 2.13 g/cm³ (providing good rigidity while maintaining lightweight characteristics for precision components)
- Melting point: ~210°C; Glass Transition Temperature (Tg): ~45°C
- Excellent mechanical strength and hardness, suitable for manufacturing precision seal rings, valve seats, and structural parts in low-temperature environments
- Outstanding chemical resistance (resistant to most acids, bases, and organic solvents), ideal for components in chemical processing equipment and corrosive fluid handling systems
- Ultra-low gas and moisture permeability, making it a top choice for hermetic seals in aerospace fuel systems, pharmaceutical packaging, and vacuum equipment
- Good dimensional stability (low coefficient of thermal expansion), ensuring consistent performance in precision parts like electronic connectors and instrument components
- Excellent electrical insulation properties (even at low temperatures), suitable for high-frequency electrical insulators and cryogenic electronic components
- Resistant to cryogenic temperatures (down to -200°C), applicable in liquid oxygen/nitrogen handling systems and aerospace cryogenic equipment
- Low flammability and smoke emission, meeting safety requirements for aerospace and industrial equipment
It delivers reliable performance in demanding industrial and precision scenarios, making it a widely used material in fields such as aerospace sealing, chemical processing, pharmaceutical packaging, and cryogenic equipment.
Key Highlights:
Excellent low-temperature stability & dimensional consistency - meets extreme operational demands in cryogenic (down to -200°C) and temperature-fluctuating scenarios like liquid oxygen/nitrogen handling systems and aerospace components
Good mechanical strength & hardness - suitable for precision seal rings, valve seats, and structural parts in corrosive or low-temperature industrial equipment
Outstanding chemical resistance (to most acids, bases, solvents) & low permeability - ensures reliability in chemical processing equipment, hermetic packaging for pharmaceuticals, and vacuum system seals
Ultra-low gas/moisture permeability & processability - enables versatility in producing high-precision, hermetic components for industries including aerospace fuel systems and electronic insulation
