Natural rubber is derived from latex liquid from rubber trees. Therubber has excellent mechanical properties, low compression set and highresilience. 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 isnot recommended for use in area where it could come in contact withoilsand hydrocarbons.
SUNWELL 400NR is also blended with SBR and PBR to obtain specific properties.
