Hydrogenated petroleum resin: Hydrogenated petroleum resin is a petroleum resin by hydrogenation reaction, the unsaturated resin in petroleum resin into saturated hydrocarbons, improve the hue of petroleum resin, odor and weather resistance of the product. Mainly divided into C5 hydrogenation resin and C9 hydrogenation resin.

C5 hydrogenated petroleum resin: C5 hydrogenated petroleum resin is ethylene cracked C5 fractions as raw materials, from the C5 component of the diene and monoene by cationic polymerization. Density of 1.0 or so, soluble in organic solvents, such as benzene, toluene, xylene, the model solvent oil, insoluble in water. Appearance of granular solid, the appearance of white or yellow, fragile, easy to generate dust, non-toxic, tasteless, non-flammable and explosive materials (Note: environmental protection). C5 hydrogenated petroleum resin has good viscosity, compatibility, thermal stability and light stability, and can improve the adhesion of the adhesive properties, many adhesives (hot-melt adhesives, pressure-sensitive adhesive) is an indispensable viscous component. Widely used in hot-melt adhesives, pressure-sensitive adhesive, construction and decoration of the construction industry, automobile assembly, tires, packaging, books binding, health products, footwear, hot-melt road signs paint, color asphalt and other industries. (Note: SBS applications and basically the same) as a paint additive, can speed up the drying rate of paint, improve the water resistance of paint, acid and alkali resistance, aging resistance and surface hardness and gloss. For welding type road marking paint, with fast drying, strong adhesion, durability, weather resistance, thermal stability, solvent-free and so on. As a medical container and packaging additives (such as blood bags, liquid medicine bags, infusion tubes, etc.) to improve its heat resistance, transparency and flexibility. The product is also used in rubber, plastic, optical recording materials and other fields.
