product description: C5/C9 copolymer resin is a kind of thermoplastic resin produced by pretreatment, polymerization, distillation and other processes of C5 and C9 fractions produced by petroleum cracking. It is not a high polymer, but a low molecular weight between 300-3000. Polymer. It has the advantages of C5 petroleum resin and C9 petroleum resin. It has the characteristics of low acid value, good miscibility, water resistance, ethanol resistance and chemical resistance. It is chemically stable to acid and alkali, and has the characteristics of good viscosity adjustment and thermal stability. Since the structure does not contain polar groups, it has good water resistance, acid and alkali resistance, weather resistance and light aging resistance. It has good solubility in organic solvents, especially in petroleum solvents, similar to other resins. The compatibility is very good, and it also has brittleness, viscosity increasing, cohesiveness and plasticity. It is generally not used alone, but as an accelerator, regulator, modifier and other resins.ã?? Product application areas: C5/C9 copolymerized petroleum resin is used in hot melt adhesives, synthetic rubber, adhesives, paints, rubber soles, tires, etc., and is suitable for high-demand rubber products such as radial tires. It can not only increase the adhesion between the rubber particles, but also It can improve the adhesion between the rubber particles and the cord. In the field of hot melt adhesives, adhesives, and adhesives, C5/C9 copolymerized petroleum resin can not only provide better initial viscosity, but also can be used like rosin resin. To adjust the durability and bonding strength of the glue and resin mixture. It can be used as a substitute for terpene resin, rosin glyceride, etc.
