Material Notes:

A carbon black-filled compound that has been plasticized with perfluorinated oil. It is the softest, lowest modulus compound in the Kalrez line. Generally it is similar in resistance to Compound 1050LF. Typically used in applications that require low sealing force or high extensibility including liquid chromatography septa, seals/seats for relief valves and tubing. Its shrinkage is higher than other Kalrez compounds.This former DuPont Dow Elastomers product line is now produced by DuPont Performance Elastomers.
