ASTM D-2000 classification: AA, BA
Temperature Range:
-50° to + 85°C (-58°F to 185°C)
Properties
Natural Rubber (NR) has excellent physical properties including abrasion resistance, good tensile strength, low compression set and high tear properties. Natural Rubber is resistant to many organic salts and acids, and some organic solvents.
