LESTAC-DP Series Petroleum Resin is a brown to dark brown granular or flake thermoplastic resin, produced by ethylene and carbon fraction of the C9 reorganization divided into nine fractions of raw materials, generated by the polymerization of low molecular weight range of 300-3000 molecular weight polymer. C9 petroleum resin is generally not used alone, but as promoters, adjusting agents, modifiers and other resins used together. Applications: A, Paint: C9 petroleum resin can increase the added paint gloss paint, paint film adhesion, hardness, acid and alkali resistance. B, Tyre and rubber: tyres and rubber are mainly the use of low softening point of C9 petroleum resin. Such resins and natural rubber particles have a good miscibility of the rubber vulcanization process is not a big impact, add oil and rubber tyres can play a tackifying resin, reinforcement, softening effect. C, Ink industry: for ink, mainly with high softening point petroleum resin. add oil and resin ink color development can play, quick-drying and brightening effects and improve printing performance and so on. D, Asphalt modifier: asphalt modifier, mainly with high softening point of C9 petroleum resin, increase the viscosity of bitumen to improve asphalt performance, the production of colored surface area; went to the stadium and other sports venues indispensable modified asphalt agent. Characters: Low acid value, Good miscibility, Adjust the viscosity and thermal stability characteristics, Water resistance, Resistance to chemicals,thanol and acid with a chemically stable,
