Hydrocarbon Resin Major Types
There are various types of hydrocarbon resins include C5 Resins, C9 Resins, C5/C9 copolymer resins, and hydrogenated resins.
C5 Resins are produced from aliphatic crackers like Piperylene and Isoprene, the current major catalyst is AlCl3. C9 Resins are produced from aromatic crackers like Vinyltoluenes, Indene, Alpha Methylstyrene, Stryene, Methylindenes, etc, the current major catalyst is BF3.
C5/C9 copolymer resins are produced from both aliphatic crackers and aromatic crackers.
Regarding to hydrogenated resins, there are some additional process like hydrogenated (use hydrogen), by this way, the double bond is neutralized and light color even water white resins are produced. There are some different types, including hydrogenated C5 Resins, hydrogenated C9 Resins, Hydrogenated C5/C9 Resin, and Hydrogenated DCPD resins.
