BS 2751:2001 acrylonitrile-butadiene rubber sheet This standard BS 2751:2001 General purpose acrylonitrile-butadiene rubber compounds. Specification is classified in these ICS categories: 83.060 Rubber This British Standard specifies compositional and physical property requirements for general purpose acrylonitrile-butadiene rubber compounds of hardness range 40 IRHD to 90 IRHD, designated BA40, BA50, BA60, BA70, BA80, BA90, and for an electrical grade acrylonitrile-butadiene rubber compound, of hardness 60 IRHD, designated E. These compounds are intended for the manufacture of items in the form of extrusions, mouldings, sheet and items cut or punched from sheet in which resistance to certain organic liquids is a necessary property, and where some stiffening of the harder grades at […]
