PCTFE, Rod, Natural

Catalog Number

ACMA00045120

Description

PCTFE (polychlorotrifluoroethylene) is a fluoropolymer material with outstanding strength, stiffness, and dimensional stability.
PCTFE has excellent chemical resistance, radiation resistance, and flammability characteristics. The material has a useful temperature range of -400°F to 380°F. PCTFE is resistant to cold flow and it has the lowest coefficient of thermal expansion of any unfilled fluoropolymer. These characteristics make it an excellent choice when dimensional stability is critical.
PCTFE is often used for aerospace applications when chemical resistance, a broad operating temperature range, and low flammability are required. It is also extensively used for cryogenic valve applications.

Application

PCTFE is widely used for:
Cryogenic and chemical processing components
Seals and gaskets
Aerospace valve seats, pump parts, impellers, diaphragms, and plugs
Laboratory instruments
Nuclear service/high radiation exposure
Liquid oxygen and liquid nitrogen valve linings
