UTECRUBBER – HN black

General Information
UTECRUBBER-HN is a saturated acrylonitrile-butadiene rubber commonly known as H-NBR. It has good mechanical properties and good chemical resistance to mineral oils and greases, propane and butane, sulfonated crude oil, water-glycol mixtures and can be used at elevated temperatures.
