TECHNICAL DATA SHEET
INRUB NBR (nitrile) RUBBER SHEET
INMARCO TYPE 403-Premium Grade
Description:
TYPE 403 is a copolymer of butadiene and acrylonitrile and is recommended when
excellent resistance to petroleum oils and gasoline is required. Nitrile’s resistance to the
more aromatic distillates of petroleum is better than neoprene.
