Hydrocarbon DCPD Resins with the grades of HCR-D100T and HCR-D238C are also known as DCPD Petroleum Resins.They are pale yellow thermoplastic resins obtained from mainly polymerizing dicyclopentadiene,unsaturated aliphatic 1,3-pentadiene (1,3-piperlene) and some monomers derived from the process of thermal cracking of naphtha.

C5/C9 Copolymerized Petroleum resins is a series of C5 Hydrocarbon Resin modified C9 Hydrocarbon resin obtained from copolymerizing of C5 fraction and C9 fraction that derived from the by-product of thermal cracking of naphtha.

Dipentaerythritol is also known as Di-Pentaerythritol, Dipenta,Di-PE, is a white octagonal crystal powder. As an important fine chemical intermediate, Dipentaerythritol is mainly used in the high class coating industry. Dipenta is often used to produce polyether, polyester, polyurethane, alkyd resin and photosensitive resin film.

Tripentaerythritol, also known as trihydroxy pentaerythritol or TPE, is a white crystalline compound synthesized from pentaerythritol and formaldehyde.
