Isoprene Rubber
IR Series is a polyisoprene rubber with high cis-1,4 using Ziegler catalyst, its molecular structure and properties that are nearly identical to natural rubber.
IR features extremely stable quality and is widely used in diverse industrial products, such as tires and belts, as a synthetic rubber alternative in place of natural rubber.
