Refined C5 Hydrocarbon Resin Applied In Adhesives

Presently, C5 Hydrocarbon resin is playing gradually more and more important role as tackfier in the adhesive and sealant industry, especially in the application of hot melt adhesive and pressure sensitive adhesive. The series of PRSAR-A petroleum resins product are a category of C5 aliphatic hydrocarbon resins applicable for hot melt adhesive and pressure sensitive adhesive. These products have an excellent compatibility with a wide variety of elastomers including natural rubber (NR), synthetic rubber, Ethylene Vinyl Acetate (EVA) and styrenic block copolymer such as SIS, SBS, SEBS, SEPS. Additionally, they also have a good compatibility with the natural tackfying resins such as terpene, rosin and thereof derivatives.A At the same time, all the properties of adhesive can be improved in various degrees by the application of these C5 petroleum resins. In recent years, C5 petroleum resins are gradually replacing the natural resin tackfier(such as terpene and rosin) due to its advantages of high deep strength, fast tack, stable adhesion performance, moderate melting viscosity, high thermal resistance, good compatibility with polymer basis, economic price.
