Several chemical modifications can improve the oil resistance of natural rubber. Natural rubber, being primarily polyisoprene, is susceptible to swelling and degradation in the presence of oils and non-polar solvents. Epoxidation is one effective method. By introducing epoxide groups along the rubber chain, the polarity of the rubber increases, making it less compatible with non-polar oils. This reduces the swelling of the rub....
