Structural Properties C9 Petroleum Resin

- Mar 29, 2019-

petroleum resin is a general term for resinous substances produced by the polymerization of olefins or cyclic olefins, the by-products of cracked petroleum, or copolymerized with aldehydes, aromatic hydrocarbons, terpenes and other compounds.C9 petroleum resin refers to a resinous substance which contains nine carbon atoms, "polymerized with olefin or cyclic olefin or copolymerized with aldehydes, aromatics and terpenes".Structure performance

It has ring structure, contains part of double bond and has high cohesion.Molecular structure does not contain polar or functional groups, no chemical activity.Good acid and alkali resistance, chemical resistance and water resistance.Poor adhesion performance, brittleness, aging resistance is not good, should not be used alone.It has good compatibility with phenolic resin, ancient Malone resin, terpene resin, SBR and SIS, but poor compatibility with non-polar polymers due to its high polarity.Combustible.Non-toxic.Mainly used as SBS universal adhesive, SBS spray adhesive, film adhesive, pressure-sensitive adhesive, hot-melt pressure-sensitive adhesive and other adhesives viscosity resin.Can also be used for neoprene adhesive to reduce the cost, the appropriate dosage will not reduce the adhesive strength of neoprene adhesive.
