Frequently asked questions about new transparent tackifiers Hydrogenated terpene/polyterpene resins

Adhesives & Sealants & Tackifiers, R&D, Coatings
Hydrogenated terpene resins are made from the hydrogenation of polyterpene resins derived from gum turpentine oil obtained from pine tree. Gum turpentine mainly includes terpene monomers α-pinene,β-pinene, limonene/dipentene andδ-3-carene. There are mainly three types of hydrogenated terpene resins: Hydrogenated terpene resin/polymer, hydrogenated terpene phenol resin and Hydrogenated Aromatic Modified Terpene Resin.
They are transparent and widely compatible with various polymers, imparting excellent heat resistance, tack, and peel adhesion to PSA‘s and hot melt adhesives. Due to the high technical requirements and high cost level, there are very few suppliers in worldwide so far. We are exclusive supplier in China.

Due to the high technical requirements and high cost level, there are very few suppliers in worldwide so far. We are exclusive supplier in China. As we know, Yasuhara Chemical in Japan is the earliest supplier of hydrogenated terpene resins. Our current grades are alternatives to CLEARON P series and YS POLYSTER UH.
