Natural Rubber / Styrene Butadiene Rubber

NR or Natural Rubber Polyisoprene is derived from latex liquid extracted from rubber trees. Originally cultivated in the Amazon region, it is now cultivated extensively in South East Asia, Africa and India. This rubber has excellent mechanical properties, low compression set and high resilience. It  also has excellent dynamic and rebound properties. The operating temperature range is   -50°C to +90°C. It is available in a wide range of hardnesses from 30° to 90° shore A. It has a good resistance to acids, alkalis and salts. It is not recommended for use in areas where it could come in contact with oils and hydrocarbons. NR is also blended with Styrene Butadiene Rubber (SBR) to obtain specific properties.
