C5/C9 Copolymerization hydrocarbon resin, gradually replace the high price of C5 hydrocarbon resin and accepted by the majority of customers at home and abroad in the hot melt adhesives, adhesives, adhesive and rubber and tyre areas. In the area of rubber and tyre, adding copolymerization hydrocarbon resin, can not only increase the adhesion of the particles, but also can enhance the rubber and glue between the radial screens, and applies to requirements such as the radial tyre rubber products. The hot melt adhesives, adhesives, adhesive areas, copolymerization hydrocarbon resin not only able to provide a better initial viscous, but also as rosin resins, can be used to adjust the persistent and bonding strength of the glue and viscosity of the resin mixture.
