Webb11 apr. 2024 · The specification includes a system of type and class designations that help to identify the properties of rubber materials and their intended applications. The ASTM D2000 type designation consists of two letters that identify the basic polymer type, such as “AA” for ethylene propylene diene (EPDM) rubber or “BA” for nitrile (NBR) rubber. More than 28 million tons of rubber were produced in 2024, of which approximately 47% was natural. Since the bulk is synthetic, which is derived from petroleum, the price of natural rubber is determined, to a large extent, by the prevailing global price of crude oil.
