NATURAL RUBBER SHEETS


Natural Rubber (NR) is the most widely use Rubber derivative. Its is derived from Rubber tree, cultivatednatural_sheet in Southern hemisphere in the form of  White viscous fluid which is later dried to evaporate moisture. The resultant material is then processed by mixing it with vulcanizing agent such as sulphur & adding other fillers. Thin Films thus drawn by calendaring & Roto curing Process are called Natural Rubber Sheets.

NR Sheets are highly abrasion Resistant & have excellent elongation property, durable & light in weight, due to these reasons NR is used in manufacturing wide variety  of Moulded & extruded products. These Rubber sheets are well suited for Sound and Noise Proofing applications.
