Scope

This specification covers a butyl (IIR) rubber in the form of sheet, strip, tubing, extrusions, and molded shapes. Primarily for parts, such as O-rings, gaskets, grommets, and seals requiring resistance to phosphate esters or low permeability to gases. Not suitable for use in contact with petroleum-base fluids due to excessive swell.
