ASTM D-2000 classification: AA
-25° to + 75°C
Natural rubber is used extensively in many applications and products, as is synthetic rubber. Natural rubber is an ideal polymer for dynamic or static engineering applications. Natural rubber cannot compare with many synthetics for heat aging and resistance to sunlight, Ozone, oxygen, but by blending it with SBR you can increase some of its better characteristics further.
Excellent dynamic properties with a low hysteresis loss, Good low temperature properties, Strong bonding to metal parts, High resistance to tear and abrasion, Ease of processing.
An extremely resilient elastomer, NR/SBR are resistant to many organic salts and acids, and some organic solvents.
Applications include Hose and tubing, Vibration Isolators, Shock Mounts, and Electrical Components amongst a host of others.
