Linagard ® NBR Technical Specifications Nitrile: Resistance to organic oils and chemicals Specifying the right lining material for oil or chemical service used to be a compromise. Natural rubber gives good abrasion resistance, but is not suitable for oil immersion. Normal nitrile-based rubbers offer excellent oil resistance, but their poor wear performance limits their use in high abrasion applications. Linagard ® NBR rubber is a nitrile based rubber specifically formulated to give good abrasion resistance in the presence of oils and chemicals. Linagard ® NBR rubber also exhibits excellent high temperature service and can be used up to 1\ 10°C (230°F) with suitable adhesives, or where mechanical fixing is employed. Design Features • R esistant to mineral / vegetable oils • Resistant to chemicals, greases and aliphatic hydrocarbons • Excellent resistance to high temperature, thermal ageing and fatigue • Good resistance to wear • L ow permeability to gases Applications • Linings for mining applications, fertiliser works and sand processing circuits where oil-based reagents are used • P ump linings and impellers for the chemical industry • Rubber coating for transmission belts Siz e/Availability • Standard Sheet siz e: 9.25m x 1.23m nominal (approx. 30ft x 4ft) • Standard thic kness range: 3.0mm to 30.0mm (approx. 1?8” to 1 3?16”) Minerals Bonding Systems and Installation Specifically designed two part bonding systems are available from Weir Minerals.
