Dicyclopentadiene (DCPD)
Dicyclopentadiene is a bicyclic cyclic hydrocarbon formed by the Diels-Alder reaction of two cyclopentadiene molecules, classified under HTS 2902.19.00.10 as a cyclene other than cyclanes or cycloterpenes. It appears as a colorless liquid with a camphor-like odor and is a key intermediate in polymer production.
Endo-Dicyclopentadiene 95% Technical Grade
Technical grade endo-DCPD at 95% purity is a primary isomer of dicyclopentadiene used in synthetic resin manufacturing, falling under HTS 2902.19.00.10 as a chemically defined cyclic hydrocarbon. The endo form is preferred for its reactivity in polymerization reactions.
High Purity Dicyclopentadiene 99%+
High purity DCPD (99%+) meets pharmaceutical intermediate standards and is classified under HTS 2902.19.00.10 as a separate chemically defined cyclic hydrocarbon. Its distillation removes impurities for use in fine chemical synthesis.
Distilled Dicyclopentadiene from Byproduct Streams
DCPD recovered and purified from C5 petroleum byproduct streams via distillation, classified as a chemically defined cyclic hydrocarbon under HTS 2902.19.00.10. This industrial-grade material serves as the primary feedstock for hydrocarbon resins.
Dicyclopentadiene Inhibited with BHT
DCPD stabilized with butylated hydroxytoluene (BHT) prevents premature polymerization during storage and transport, classified under HTS 2902.19.00.10 per Chapter 29 note (f) for added stabilizers. The stabilizer level is minimal and necessary for preservation.
