kel-f plastic

Kel-F is a fluorochemical product also known as CTFE.
It is inert to chemicals and functions over a -400 degree to +400 degree F temperature range.
Kel-F has excellent electrical properties and may be machined to precise dimensions.
Compression, impact and tensile strength are high over a wide temperature range.
