DESCRIPTION:
NR / SBR blend rubber sheets / rolls are used in the commercial and industrial applications. This specifically designed rubber material is long-¬lasting that is suitable for operational use which provides excellent mechanical properties like high resilience, low compression set, high resistance to cut, tear & abrasion & also offers resistance to many acids, alkalis & salts. The operation temperature range is (-¬20°C to +80°C). It is available in wide range of hardness from 40 Shore A to 80 Shore A. It has very good physical properties like Tensile strength, wear & tears properties, Abrasion resistance.
APPLICATIONS:
NR / SBR Rubber sheets / rolls are used for wide range of applications like skirt board, bridge bearing, gasket for high pressure packing, heavy weight machinery packing, Para-¬quality for sand/shot blasting machinery & used as shock absorber. NR / SBR Rubber sheets/rolls can be used as shelf liner; workstation table liner and work area rubber lining that can with and moderate chemicals & alkaline solutions. These sheets can also be used for anti-abrasion lining for material handling machinery in mines alike industries
PROPERTY:
Excellent resistance to inorganic chemicals, water, air & heat up to 80°C. Poor resistance to Ozone, UV, Sunlight, oil & solvents & organic chemicals.

STORAGE OF PRODUCTS
Do not expose rubber sheet to direct sunlight, sheets away from heat source, preferably in dark, air ventilated room will help give longer life & optimum properties
Do not remove polythene packing before use to prevent it from exposure of atmospheric oxygen, ozone & polluted air. Do not store rubber sheet rolls in open, even after covering it with tarpaulin to protect from air & rain. Always keep rolls in vertical position ONLY
Keep rolls away from solvent, oil & fuel storage. Do not use hooks while loading/unloading the rolls. Inspect sheet for smooth surface & hardness (with rubber hardness tester)
