WebNatural Rubber Products. Physical & Mechanical Properties / Chemical Resistance / Thermal Properties / Environmental Performance / Natural Rubber Applications. What is Natural Rubber? Natural rubber, also known as polyisoprene rubber, consists of polymers of the compound isoprene as well as impurities from other organic compounds and some water. Rubber exhibits unique physical and chemical properties. Rubber's stress–strain behavior exhibits the Mullins effect and the Payne effect and is often modeled as hyperelastic. Rubber strain crystallizes. Because there are weakened allylic C-H bonds in each repeat unit, natural rubber is susceptible to vulcanisation as well as being sensitive to ozone cracking. The two main solvents for rubber are turpentine
