C5 Dicyclopentadiene Resin Sheet
In the past, DCPD was extracted from coal tar, which was not noticed because of its very small quantity. With the development of the petroleum industry, it can be extracted from the C5 fraction formed by petroleum cracking products. It has abundant sources and the price is low. The DCPD of different purity can be applied to individual applications. The viscosity of the DCPD monomer is very low (about 0.3Pa*s), and it can be molded at low temperature and pressure. The mold can be filled within a short period. Therefore, it is often used in the “Reaction Injection Molding”. polymerization to generate Poly-DCPD products. This method has the advantages of energy-saving, high material mixing efficiency, low cost, good product performance, and flexible product design. So far, it has been developed in many applications, such as corrosion-resistant and high-temperature coatings, shipbuilding industry, automobile industry, optics, and electronic products, etc. Because DCPD contains unsaturated double bonds in its molecular structure, it can also undergo addition or polymerization reactions, so it is often used in the production of petroleum resins, unsaturated polyesters, and Cyclo Olefin (Co)-polymers. It is also used in the production of medicine, perfume precursors, epoxy resin curing agents, lubricant additives, flame retardants, etc.
