Better compatibility C5 & C9 Copolymer Resin for Adhesive

Product name: C5&C9 Copolymer Resin

Type: HC - 52110

Synonyms: Copolymer Petroleum C5&C9 ,Copolymer C5 and C9 Hydrocarbon Resin ,Copolymer Resin.Copolymerized hydrocarbon Resins


This ratio determines the aliphatic/aromatic balance of the resin, which is an essential determinant of the resin’s compatibility.This kind of coplymerized C5 and C9 resin has best anti yellowing property​,which to aviod the finished hot melt adhesive color changed into yellow in short time.

Copolymerized hydrocarbon Resins has better solubility in organic solvents especially in oil solvent, as well as good compatibility with other resins.

Aliphatic modified aromatic resins are particularly suitable for uses as tackyfying and rheological property modifying resins in hot melt adhesives, pressure sensitive adhesives and solvent adhesives.

In adhesive,C5 and C9 resin have yellowing resistance ,which can produce high level adhesive applications. They are compatible with a broad range of resins and polymers, such as EVA, Natural rubber, SIS, SBS. SEBS. Narrow molecular weight distribution enable them to be best resin for use in SIS based high performance formulations.
