Mainly used for making medicines, pesticides and resin products.
Mainly used as the third monomer of EPDM rubber.
DCPD mainly comes from the C5 fraction of kerosene or petroleum cracking. It can be regarded as a primary raw material and does not need to be produced through organic synthesis. Another advantage of DCPD is its active polymerization performance. During the polymerization process of ethylene propylene, it can basically completely enter the polymer. However, due to its shortcoming of slow vulcanization speed of EPDM rubber, it is now used in industrial production. Used rarely.
DCPD has two isomers, endo and exo. What is usually obtained is endo, which is converted into exo through a special conversion method.
Using dicyclopentadiene (DCPD) as the main material and using reaction injection molding (RIM), a large amount or complex shapes of thermosetting cross-linked polydicyclopentadiene (PDCPD) can be produced in a very short time ) resin products. Its products are used in shell covers of automobiles, construction machinery, agricultural equipment, medical equipment and other equipment.
Toxicity: Inhalation will cause headaches, but long-term exposure, such as more than 2 months, will form a habit. Can irritate eyes, skin, respiratory and digestive systems. Can depress the central nervous system. In animal experiments, it has been found to damage the kidneys of rats. LD50 Rat intraperitoneally injected 0.31 mL/kg or 200 mg/kg, oral 0.35 mL/kg or 353 mg/kg, 419 mg/kg, transdermal 4.46 mL/kg, mice oral 190 mg/kg, intraperitoneal injection 200 mg/kg, LC50 is 660 mg/L/4 hr for rats and 145 ppm/4 hr for mice. . Devices and equipment containers should be sealed and ventilation should be strengthened. The maximum allowable concentration in the air is 5 mg/m3. Operators should wear protective equipment. Those who experience acute poisoning should be moved to fresh air and treated according to general narcotic drug poisoning.
