What is PCTFE?
PCTFE stands for polychlorotrifluoroethylene, which is a fluoropolymer material known for its strength, stiffness, and dimensional stability.
What are the key properties of PCTFE?
The key properties of PCTFE include being dimensionally stable, rigid, and resistant to cold flow. It also has excellent chemical resistance, high compressive strength, low deformation under load, and near zero moisture absorption. Additionally, PCTFE is non-flammable and has radiation resistance.
What is the useful temperature range of PCTFE?
The useful temperature range of PCTFE is from -400°F to 380°F.
What applications is PCTFE commonly used for?
PCTFE is commonly used for cryogenic and chemical processing components, seals and gaskets, aerospace valve seats, pump parts, impellers, diaphragms, and plugs, laboratory instruments, and nuclear service/high radiation exposure. It is also used for liquid oxygen and liquid nitrogen valve linings.
What are the characteristics of PCTFE that make it an excellent choice for certain applications?
PCTFE's excellent chemical resistance, radiation resistance, and low flammability characteristics make it an excellent choice for applications where dimensional stability is critical, such as in aerospace and cryogenic valve applications.
What is the color of PCTFE?
The color of PCTFE is natural/white.
What is the gas permeation and outgassing property of PCTFE?
PCTFE has very low gas permeation and outgassing properties.
What are the material loss percentages for PCTFE?
The total mass loss (TML%) of PCTFE is 0.01% and the collected volatile condensable materials (CVCM%) is 0.00%. The water vapor regained (WVR%) is also 0.00%.
What does it mean for PCTFE to be dimensionally stable and resistant to cold flow?
Being dimensionally stable means that PCTFE maintains its shape and dimensions even under various temperature and environmental conditions. Being resistant to cold flow means that it does not easily deform or flow under pressure or load, even at low temperatures.
What are some specific applications of PCTFE in the aerospace industry?
In the aerospace industry, PCTFE is commonly used for valve seats, pump parts, impellers, diaphragms, and plugs.
