Rubber is a polymer of isoprene. It is sometimes called polyisoprene. There are two forms of polyisoprene: cis-polyisoprene is the soft, flexible material we associate with the term "rubber", gutta-percha, or trans- polyisoprene, is a much harder material. This 500mt/y TPI plant (Trans PolyIsoprene, Trans Isoprene Rubber, Trans-l,4-PolyIsoprene) is a pilot-testing scale one developped according to the years research result of professor Huang BaoChen following China's 863 plan. The company's target is to realize industrialization of such TPI technology at four stages.
