Kel-F - PCTFE (PolyChloroTriFluoroEthylene) Kel F is a
fluorocarbon-based polymer and is commonly abbreviated PCTFE. PCTFE
offers the unique combination of physical and mechanical
properties, nonflammability, chemical resistance, near zero
moisture absorption, and excellent electrical properties. These
characteristics cannot be found in any other thermoplastic
fluoropolymer with a useful temperature range of -400°F to +400°F.
PCTFE also has extremely low outgassing, making it well suited for
use in aerospace and flight applications. Note: Kel-F® is a
registered tradename of 3M Company. In 1996, 3M discontinued
manufacturing of Kel-F & today, Kel-F is still the most
commonly used tradename used to describe PCTFE.
PCTFE is a kind of perfect sealing material under low temperature,
high vacuum system and high pressure working conditions. It has
excellent rigidity, low temperature resistance, cryogenic fluid
resistance, and airflowresistance.
Products available:
1). PCTFE rod: (Dia. Φ 5mm~ Dia. Φ 136mm)
2). PCTFE Sheet (100mm*100mm; 200mm*200mm; 300mm*300mm; 400*400mm,
special size can be customized)
3). PCTFE Bush/PCTFE tube (Φ 30mm~Φ 600mm)
4). PCTFE machined parts.
Application:PCTFE is a good choice for instrumentation, laboratory, aerospace
and flight applications. Other common applications include
cryogenics, valves, seals, and film for food and pharmaceutical
packaging.
