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.
SUNWELL 400NR is also blended with SBR and PBR to obtain specific properties.

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.
