Description
1.C5/C9 Copolymerized Petroleum Resin is a thermoplastic resin, C5, C9 fraction of petroleum by-product of decomposition with processing pre-treatment, polymerization and distillation. 2.C5/C9 has advantages both of C5 and C9 petroleum resin: low acid value, good miscibility, waterproof, ethanol resistance and chemical resistance and other characteristics of acid resistance, chemical stability in acid-bases, adjustment in viscosity, good thermal stability, weather resistance and light aging resistance because of non-polar groups in its structure. C5/C9 has good solubility in organic solvents especially in oil solvent, as well as good compatibility with other resins. 3.It also has brittle, increasing viscosity, cohesiveness and plasticity.
