Carbon nine petroleum resin, as an important chemical raw material, plays an important role in multiple industrial fields due to its unique physical and chemical properties. Among them, C9 petroleum resin low melting point resin is gradually becoming the focus of market attention due to its excellent characteristics. Recently, new progress has been made in the study of the characteristics of C9 petroleum resin low melting point resin, further highlighting its unique advantages in industrial applications.
1. Basic physical properties
Molecular weight: usually between 300 and 3000, with some sources mentioning an average molecular weight of up to 2000 to 5000.
Softening point: relatively low, generally controlled by special processes to meet the needs of different application fields. The coal tar softening point measurement method is used for testing. The softening point range of some products is between 80 ℃ and 140 ℃, and there are also reports that the softening point is less than 150 ℃.
Appearance: It is a solid in the form of light yellow to light brown flakes, granules, or blocks, transparent and glossy.
2. Main chemical characteristics
Low acidity: This makes it exhibit good stability in certain chemical applications.
Good miscibility: It can dissolve in various organic solvents such as acetone, methyl ethyl ketone, cyclohexane, dichloroethane, ethyl acetate, toluene, gasoline, etc., making it easy to apply in various chemical systems.
Water resistance: It has good water resistance.
Chemical resistance: It has chemical stability to acids and bases, and is resistant to chemicals such as ethanol.
Thermal stability: It can maintain stability within a certain temperature range during processing and use.
3. Application Features
Thickening and adhesion: In the fields of rubber, adhesives, etc., C9 petroleum resin low melting point resin can be used as a thickening agent to improve the adhesion and bonding strength of products.
Plasticity: Easy to process and shape, suitable for various molding processes.
Adjust viscosity: The viscosity of the product can be adjusted as needed to meet the needs of different applications.
Cost reduction: In some applications, such as the formulation of phenolic varnish, replacing rosin modified phenolic resin and rosin calcium grease with equal amounts of C9 petroleum resin still meets relevant standards, but the cost is significantly reduced.
4. Other characteristics
Brittleness: C9 petroleum resin has a certain degree of brittleness, which may be a desirable characteristic in some applications, but may need to be reduced through modification in other applications.
Color and odor: Light in color, odorless, suitable for occasions where color and odor are required.
In summary, C9 petroleum resin low melting point resin has various excellent characteristics, making it widely used in various fields such as coatings, rubber, adhesives, inks, etc. At the same time, with the continuous advancement of technology and the continuous development of the market, the application fields of C9 petroleum resin low melting point resin will be further expanded.
