Nitrile Rubber Sheets

---

Nitrile or NBR (Acrylonitrile Butadiene Rubber) is a synthetic rubber highly resistant to Petroleum Products such as solvents, Petrol, diesel, kerosene, fuel oil & a wide range of Chemicals & acids. It is a co-polymer of Butadiene & acrylonitrile. NBR is available in different grades depending on its application, low acrylonitrile content rubber is more flexible at low temperatures and is generally used in vehicle door-window seals, wipers, o-rings, hand gloves, and adhesives. The intermediate type is used for comparatively less flexible products such as floor mats and Sheets. High acrylonitrile content Rubber is meant for rigid and highly resistant to hydrocarbon and oils products such as hydraulic & Industrial Hoses, gaskets, and Diaphragm Rubber Sheets.

Features: 

Nitrile Rubber or NBR Rubber Sheets are widely used in Industrial & Automobile applications due to their resistance to Petroleum products, low compression set, and impermeability to fluids & gases. NBR Sheets are used between flanges and similar joints which are subjected to water & air pressure.

Application: 

1. In Automobile parts, Petrochemical Industry, Chemical Industry, Steel Mills, Pharmaceuticals & other related industries where it is used as gaskets, oil seals, and Fluid & oil resistant flooring.
2. It is blended with cork to make Rubberized Cork sheets, used in electric transformers.
3. Insulation sheets made from low-density NBR Rubber, are used for air conditioner ducting to prevent heat & temperature loss.
4. Nylon Fabric or steel wire-mesh reinforced Nitrile Rubber Sheets are very popular in making Diaphragms.
5. It can be blended with PVC to make hard sheets for specialized applications.

Composition: 

NBR is manufactured using a blend of Nitrile Polymer, mineral fillers (calcium carbonate), carbon black & accelerators such as MBTS, TMT, Zinc oxide, Sulphur, Wax, and Paraffin oil. These ingredients improve material flexibility, Tensile strength & better stability at high temperatures.

• Size:             Length - up to 10 meters, Width- up to 1500mm.
• Thickness: Rubber Sheets manufactured in the range of 0.5mm to 50mm. 
• Surface:      Smooth on both sides OR Fabric impression on one side & smooth at the other.
