Nitrile Rubber Sheeting – BS2751 standards and specifications

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 temperatures below –20 ºC can be tolerated.

NOTE 1: Compounds in the BA series may not have good electrical insulating properties whereas the compound designated E is available with specific electrical properties.

NOTE 2: Ozone, which is naturally present in the atmosphere, can cause unprotected nitrile rubber to crack when it is strained, and this can often lead to failure of the part. The nitrile rubber compounds specified in this standard are not required to be compounded to be resistant to ozone attack and their resistance to ozone is not tested. Potential users should seek technical advice if they are unsure as to whether ozone resistance is required for their application. There is currently no British Standard for ozone resistant nitrile rubber compounds.

NITRILE BS2751 RUBBER SHEETING

KEY FEATURES

PRODUCT DESCRIPTION

Our nitrile BS2751 rubber sheeting is a high grade pure NBR (acrylonitrile butadiene) nitrile sheeting. it provides exceptional durability as well as resistance for use in a variety of applications. A key feature of this particular grade is the products excellent oil, fuel and chemical resistance. This enables our sheeting to provide the highest level of safety in demanding applications. In addition to having good mechanical properties, the sheeting also has excellent resistance to hydraulic fluids, aliphatic hydrocarbons, mineral oils, silicone and vegetable oils. We can supply this product in a wide range of sheet thicknesses and sizes to suit your exact requirements. We can also manufacture bespoke finishes and sizes, subject to minimum order quantities.

This compound is independently tested to conform to BS2751 safety standards.
This material is fully CE, PAH, RoHS and REACH compliant.

Aside from offering excellent fuel and oil resistance, our nitrile BS2751 rubber sheeting also provides good physical properties. This product features a tensile strength rating from 9.0 to 14.0 (MPa) depending on the sheet hardness. A higher tensile strength will provide superior durability and tearing resistance but will compromise on the flexibility of the sheeting. It is important to consider the application when selecting the shore hardness and thickness of the sheeting you want. Don’t hesitate to get in contact with us, if you are unsure which product will best suit your application.
