C-9 Petroleum Resins is a kind of thermal plasticizing resin produced by C5, C9 fraction, by-products of petroleum cracking, through pretreatment, polymerization and distillation. It is not a high polymer but a low polymer with the molecular weight between 300-3000.It has the chemical stabilizing property to acid and alkaline, viscosity adjusting and thermal stabilizing.C-9 Petroleum Resins are not used independently, but have to be used together with other kinds of resins as promoters, adjusting agents and modifiers.C-9 Petroleum Resins are used in paint to increase brightness, adhesive force, film hardness, acid resistance and alkali resistance, in adhesive to increase adhesiveness, resistance to acid, alkaline and water, in rubber compounding to used as takifier, reinforcer, extender, and lower moony viscosity of compounds, In printing Inks for color spreading, fast drying, and brightening effect. It is a granular solid with color from light yellow to brown. It has the properties of good solubility, indissolubility, water resistance, insulation and very good chemical stability over acid and alkali. It can be substitute for rosin, synthetic, hot melt adhesive and even suitable for other modified resin.
