Polychlorotrifluoroethylene
PCTFE for short, is a thermoplastic polymer known for its high chemical resistance, low gas permeability and broad temperature resistance. Here is a description for PCTFE:
Properties of PCTFE:
High chemical resistance:
PCTFE shows excellent resistance to a wide range of chemicals, acids and bases. This property makes it particularly suitable for applications in chemical and aggressive industrial environments.
Low gas permeability:
PCTFE has a very low gas permeability, which makes it attractive for use in gas and fluid technology. This enables its use in applications where gas barriers are important.
Wide temperature resistance: PCTFE retains its mechanical properties over a wide temperature range. It can withstand temperatures from around -200 to +150 degrees Celsius, making it suitable for extremely low and high temperatures.
Mechanical strength:
PCTFE shows good mechanical strength and is comparatively stiff, which makes it suitable for structural applications.
Low water absorption:
PCTFE absorbs only small amounts of water, which results in low moisture absorption and retains its electrical properties.
Electrical insulation:
PCTFE is a good insulator and is used in the electrical industry for the manufacture of insulators, cable sheathing and other electrical components.
Applications of PCTFE:
PCTFE is used in various industrial sectors, including:
Chemical industry: valves, pumps, pipes and fittings due to its chemical resistance.
Gas and fluid technology: Seals, valves and components in applications where low gas permeability is important.
Aerospace: Insulation materials, valves and parts in extreme temperature applications.
Electrical industry: insulators, cable sheathing and other electrical components.
Due to its specific properties, PCTFE is a preferred material in industries where high demands are placed on chemical resistance and temperature stability .
