DCPD Resin is a pale yellow thermoplastic resin, which is polymer of low molecular weight made of dicyclopentadiene and others by special process, and generated by poly-reaction at a certain temperature and pressure. DCPD Resin has characteristics of high bromine value and light color, good liveness and compatibility with other bases in the rubber, especially in high-grade rubber, playing a good role in activity and solubility.
