As a big country in the petrochemical industry, China is estimated to produce more than 49 million tons of ethylene in 2022, ranking first in the world. In the by-products of the ethylene industry, a large amount of C5 and C9 are wasted as fuel additives due to lack of reasonable uses and related technologies. Rational use of C5 and C9 to reduce pollution and waste, increase the added value of products, and optimize the industrial structure is a difficult problem for China today. In the exchanges with major developed countries in the world, Chinese entrepreneurs have learnt and recognized the polymerization technology of DCPD. Through the unremitting efforts of several generations, we gradually formed a DCPD polymerization technology with Chinese characteristics. Until now, a closed-loop structure of the whole industrial chain of raw materials, equipment, molds, tooling, product production and waste treatment has been formed.

PDCPD, based on dicyclopentadiene, is produced into polydicyclopentadiene polymer (PDCPD)through engineering transformation. It is a thermosetting resin with high mechanicalproperties. The material has strong mechanical properties at high and low temperatures. Water absorption and radio transparency.
