Basic Introduction
English name: petroleum resin petroleum resin petroleum cracking by-product of C5, C9 fraction, by pre-treatment, polymerization and distillation process the production of a thermoplastic resin, it is not a polymer, but the molecular weight range of 300-3000 oligomers.
Source
Petroleum resin oil derivatives by named sources, it has low acidity, good compatibility, water resistance, alcohol and chemical resistance and other characteristics of chemically stable pH, and adjust the viscosity and thermal stability characteristics. Petroleum resin is generally not used alone, but as promoters, regulators, modifiers and other resins used together.
Categories
Petroleum resin is generally classified as C5 alphatic (aliphatic type), C9 aromatic (aromatic hydrocarbons), DCPD (Central fat diene, cycloaliphatic) and pure monomer (eg poly SM, AMS (alpha methyl styrene) and other products) other four types, which are all composed of molecules of hydrocarbons, it is also known hydrocarbon resin (hydrocarbon resins, HCR). Petroleum resin according to different raw materials are divided into aliphatic resin (C5), alicyclic resin (DCPD), aromatic resin (C9), aliphatic / aromatic copolymer resin (C5/C9) and hydrogenated petroleum resin. C5 hydrogenation petroleum resin, C9 petroleum resin hydrogenation
Advantages
Petroleum resin is a new development in recent years, chemical products, due to a low price, good compatibility, low melting point, water resistance, and chemicals such as ethanol can be widely used in rubber, adhesives, paint, paper, ink other industries and fields.
Structure
Petroleum resin model of chemical elements: petroleum resin C9 Hydrocarbon Resin is the most widely used and C5 petroleum resin. C5 petroleum resin, C5 petroleum resin for its peel adhesive strength, rapid viscosity, adhesive properties of stable, moderate melt viscosity, good heat resistance, compatibility with the polymer matrix is good, and the price is low, began to gradually replace the natural resin tackifier (rosin and terpene resin). Refined C5 petroleum resin in hot melt adhesive characteristics: mobility, and can improve the wettability of the main material, viscous, and has outstanding tack performance. Good aging resistance, light color, transparency, low odor, low volatile matter. In the hot melt adhesive, can be used alone as a ZC-1288D Series tackifying resin can also be mixed with other tackifying resins used to improve certain properties of hot melt adhesive.

The use of oil by-product of cracking olefins for polymerization of olefins or ring or with aldehydes, aromatics, terpenes and other copolymer resins made of the general nature of the material. With acid price and good miscibility, low melting point, water resistance, and resistance to chemicals, ethanol, and so on. Soluble in aliphatic hydrocarbons and chlorinated hydrocarbons, insoluble in lower alcohols and ketones. Mainly used in paint industry, such as oil and resin emulsion used to enhance the synthesis of latex paint, light-colored petroleum resin for the manufacture of oil-based varnish to improve the gloss and adhesion. Is also used in rubber industry, with a low softening point resin as a plasticizer, a resin with high softening point to improve the hardness of synthetic rubber. Also used for preparation of hot melt adhesive, and traffic signs paint, printing ink and paper hydrophobic agent.
