Chemical Engineers: How to Soften Rubber? | Adventure Rider
You can't, in general. As it ages, rubber loses the plasticizers that are incorporated into the chemical mix. Continued cross-linking sometimes also makes the rubber harder as it ages. This is the reverse of men BTW. You can soften rubber with different chemicals though. Naptha also works for some others, MEK.
The sulfur reacts with polyisoprene to replace some C─H bonds with disulfide bonds. As a result, the polymer chains become connected by cross-links that may contain one, two, or more sulfur atoms (Figure 28.9). These cross-links increase the rigidity of the rubber because most of the chains are linked into a larger molecule.
