Product Description 

C5 hydrocarbon resin, also known as petroleum resin, is an olefin thermoplastic resin with certain viscosity and adhesion, and can maintain stability at high temperatures. It is mainly polymerized from C5 fraction raw materials obtained from petroleum cracking. This resin is inexpensive and has excellent properties such as acid resistance, alkali resistance, aging resistance, and weather resistance.

As an important chemical raw material, C5 petroleum resin is widely used in the manufacture of coatings, adhesives, adhesives, inks, adhesives, and rubber plasticizers. The emergence of C5 petroleum resin has not only improved the comprehensive utilization rate of petroleum resources, but also provided strong support for the development of related industries.

(1) Coatings

Used as an adhesive and plasticizer for coatings, C5 hydrocarbon resin provides good adhesion, strength and weather resistance. It is commonly used in outdoor architectural coatings, road marking coatings, paints and coatings. In coatings, this resin can improve the gloss and hardness of the paint film, improve weather resistance and adhesion.

(2) Adhesives

It is an excellent adhesive and has a wide range of applications in adhesives. It can provide good viscosity and rheology, making the coating easy to apply and lay. In addition, C5 hydrocarbon resin can also improve the viscosity of the adhesive and provide good strength and durability during the curing process.

(3) Ink

Widely used in ink manufacturing, especially solvent-based inks. In inks, it can provide good fluidity and drying, and can enhance the adhesion and printing quality of the ink.

(4) Rubber plasticizer

Due to its good adhesion and plasticity, C5 petroleum resin is widely used in rubber products as a plasticizer and adhesive. It can improve the flexibility, ductility and durability of rubber products, and can provide excellent adhesion and bite force.

Application fields. C5 hydrocarbon resin is mainly used in adhesives, pressure-sensitive adhesives, road marking coatings, etc. It has gradually replaced natural tackifying resins and occupied an important position with its high peeling bond strength, good quick adhesion, stable bonding performance, moderate melt viscosity, good heat resistance, and good compatibility with polymer matrices. C9 petroleum resin is mainly used in paints, anti-corrosion coatings and other fields. Adding petroleum resin to paint can increase the gloss of paint, improve the adhesion, hardness, acid resistance and alkali resistance of the paint film.

Performance and characteristics. C5 resin has the characteristics of good fluidity, good viscosity, excellent aging resistance, and the best balance between cohesive strength and peel strength. In addition, it has light color, transparency, low odor and low volatiles. C9 petroleum resin has the characteristics of low acid value, good miscibility, water resistance, ethanol resistance and chemical resistance, chemical stability to acids and alkalis, and good viscosity adjustment and thermal stability.

Odor. The odor of C5 hydrocarbon resin is relatively small, while the odor of C9 is relatively large.

Compatibility. C5 petroleum resin has good compatibility with oils, greases and other synthetic resins, can be dissolved in many solvents, and has good water resistance and acid resistance when combined with other substances. C9 resin has good compatibility with phenolic resin, coumarone resin, terpene resin, SBR, SIS, etc.

With the continuous development of the global economy and the accelerated advancement of industrialization, the market demand for C5 petroleum resin continues to grow. Especially in industrial fields such as coatings, inks and rubber, the demand for high-performance and environmentally friendly C5 petroleum resin is growing. In the future, with the continuous advancement of technology and the upgrading of industries, the market prospects of C5 petroleum resin will be broader.

C5 petroleum resin has the characteristics of light color, high softening point and good thermal stability. Its good compatibility enables it to be mixed with other materials such as resins, rubbers and plastics to improve the comprehensive performance of the product. In addition, C5 petroleum resin also has good weather resistance and chemical corrosion resistance, and can maintain stable performance in harsh environments.

The production of C5 petroleum resin mainly includes raw material pretreatment, polymerization reaction, distillation separation and packaging. First, the C5 fraction is refined to remove impurities and unstable components. Then, polymerization reaction is carried out under the action of catalyst to form high molecular weight resin. After distillation separation, C5 petroleum resin products with different molecular weights and properties are obtained. Finally, after packaging, they can be put on the market for sale.
