LESTAC-C100 C5/C9 copolymerized petroleum resin, light yellow granular thermplatic resin, whose materials are C5 fraction and C9 fraction, by- products of petroleum cracking, through pretreatment, catalysis or thermal polymerization and distillation, a new product for the market. It has the good characters of C5 hydrocarbon resin and C9 petroleum resin. The prices of these resins are not expensive as C5 petroleum resins, but have a better adhesiveness than C9 hydrocarbon resin. Usually the colors of thermal polymerized C5/C9 copolymerized resin are darker than cold-polymerization. Application: LESTAC-C100 as tackifying resins mainly used in adhesive such as printing ink, rubber, painting and tire fields, especially in radial tyre. Characters: Good miscibility, Good peeling strength, Good heat-resisitance, Waterproof, Low molecular weight, Low acide value, Excellent compatibility with EVA, Rubber, SIS, SEBS, SBS,SEPS,EVA
