China Hydrocarbon Resin

China Hydrocarbon Resin is a special type of synthetic resin produced by distilling petroleum or natural gas. The following is an introduction to the characteristics of hydrocarbon Resin:

1. Basic physical and chemical properties

The molecular weight of China hydrocarbon Resin is usually oligomers ranging from 300 to 3000. According to different polymerization conditions, the generated hydrocarbon Resin has different softening points, ranging from viscous to solid, and colors from light yellow, amber to black. The relative density (15 ℃) is 0.98-1.06, and the refractive index is 1.53-1.60.

2. Chemical resistance and stability

Hydrocarbon Resin has the characteristics of water resistance, ethanol resistance, and chemical stability to acids and bases. And it has good thermal stability and can maintain stable performance within a certain temperature range.

3. Solubility and miscibility

Soluble in various organic solvents such as acetone, methyl ethyl ketone, cyclohexane, dichloroethane, ethyl acetate, toluene, gasoline, etc., but insoluble in ethanol and water. China Hydrocarbon Resin has good miscibility with synthetic rubber and other synthetic resins, and can be used together to improve material properties.

4. Function and application features

1. Adhesive and wetting effects: China Hydrocarbon Resin can provide adhesive and wetting effects, playing a key role in coatings, adhesives, hot melt adhesives, and other fields.
2. Glossiness and adhesion: Adding hydrocarbon Resin to paint can increase the glossiness of the paint, improve the adhesion, hardness, acid and alkali resistance of the paint film.
3. Adhesive performance: Hydrocarbon Resin can improve the adhesive strength, acid resistance, alkali resistance, and water resistance of adhesives and pressure-sensitive tapes, and effectively reduce production costs.
4. Color development and fast drying performance: Adding hydrocarbon Resin to ink can achieve color development, fast drying, and brightening effects, improving printing performance.
5. Types and classification characteristics
According to the raw materials, it is divided into aliphatic resins (C5 hydrocarbon Resins), cycloaliphatic resins, aromatic resins, aliphatic/aromatic copolymer resins, and hydrogenated hydrocarbon Resins. But for example, C9 hydrocarbon Resin has a cyclic structure, contains some double bonds, and has high cohesion; C5 hydrocarbon Resin, on the other hand, has good compatibility with natural rubber particles and has a relatively small impact on the rubber vulcanization process.
In summary, China hydrocarbon Resin has various excellent characteristics and properties, making it widely used in various fields such as coatings, adhesives, inks, rubber, etc.
