IIR - Butyl Rubber

JSR IIR Butyl Rubber
JSR IIR excels in air impermeability and weather, ozone
and aging resistance. Heat aging resistance is improved
for chlorobutyl and bromobutyl when combined with
regular butyl rubber.
Because of its air impermeability, JSR IIR is ideal for
rubber tubing caps and syringe piston gaskets.
