PINPRUBBER – HN is a saturated acrylonitrile-butadiene rubber, suitable for applications in aliphatic hydrocarbons like propane or butane, mineral oils, and greases, and sulfonated crude oil. It can be used in many diluted acids and bases and salt solutions at elevated temperatures and in water-glycol mixtures. It is not compatible with fuels with high content of aromatic hydrocarbons, gasoline, ketones, esters, hot water, and low molecular weight organic acids.
