Polydicyclopentadiene can be made into various parts by reaction injection molding. Used as auto parts, such as bumpers, bumpers, dashboards, fenders, etc., can also be used as sports goods, chemical resistant containers, etc.
Polydicyclopentadiene is a homopolymer or copolymer of dicyclopentadiene . It is a cross-linked three-dimensional network structure engineering plastic. Dicyclopentadiene has a density of 1.04 g / cm3 and a heat resistance of 120 ° C. Cold resistance -40 ℃. Resistant to general acids, alkalis, organic solvents, but not to aromatics and halogenated hydrocarbons. The flexural modulus is 1790-2070MPa. The tensile strength is 34MPa. The heat distortion temperature is 185.5 ° C. Izod impact strength of notched 427J / m. In the presence of a catalyst consisting of tungsten hexachloride and monochlorodiethylaluminum, it is prepared by ring - opening disproportionation polymerization of dicyclopentadiene .
