Natural Rubber Sheets
Natural rubber is derived from latex liquid from rubber trees. The rubber has excellent mechanical properties, low compression set and high resilience. It also has excellent dynamic and rebound properties.
It is available in a wide range of hardness from 30o to 90o shore A.
It has good resistance to acids, alkalis and salts. Natural rubber is not recommended for use in area where it could come in contact with oils and hydrocarbons.

Produced from coagulation of Liquid milk called latex derived from Rubber Plant along with some chemical like ammonium alginate. Natural Rubber is derived from Rubber Plant cultivated in the Southern region of India especially at kottayam (Kerala).

Application:
Natural rubber sheets are used as skit board sheets, bride bearing pads, shot plasting sheets, high tensile tangum sheets, commercial sheet with or without cotton/nylon insertion etc.

Features:
NR Sheets are Abrasion resistant that's the reason Automobile tires are namely composed of NR Polymer, Can be made available in variety of colors like Blue, Red, Black etc. Natural Rubber Sheets offers good Physical & Mechanical properties like High Elongation, Tensile Strength, Smooth & Glossy finish. 

Composition: 
Manufactured using blend of RSS, Carbon Black, filler & Rubber Processing Chemicals.

Technical Specifications: 
Natural Rubber Sheets could be manufactured as per the mentioned Properties & Variation depending upon application requirement.

   a Specific Gravity (gm / cm 3) - 1.35 to 2.10
   b Hardness (Shore A, ±5) - 60 to 75
   c Tensile Strength, min (kg / cm 2 ) - 50 to 80
   d Elongation at break, min(%) - 150 to 400
