Copolymer petroleum resin factory

Copolymer petroleum resin is a polymer material with unique physical properties. The following is a detailed introduction of its physical properties by copolymer petroleum resin factory:

1. Appearance and color

C5/C9 copolymer petroleum resin is a solid granular substance ranging from light yellow to brownish yellow. The color depth is affected by the raw materials and polymerization process, but generally speaking, the color of copolymer petroleum resin is relatively light and has good transparency.

2. Softening point and viscosity

Softening point: It has a high softening point, usually above 100 ℃. This means that copolymer petroleum resin can maintain a stable physical state at higher temperatures and is not easily softened or deformed.

Viscosity: The viscosity of copolymer petroleum resin is moderate, which gives it good processability and coating rheological properties. In the fields of coatings, inks, adhesives, etc., moderate viscosity helps to achieve sufficient mixing and uniform coating of resin and substrate.

3. Solubility and miscibility

Has good solubility and miscibility with multiple solvents. It can dissolve in various organic solvents, such as petroleum ethers, alcohols, ketones, etc. This good solubility enables copolymer petroleum resin to be fully mixed with other resins, pigments, fillers, and other components to form a uniform mixture, thus meeting various application needs.

4. Density and molecular weight

Density: Moderate density, usually around 1.0. This makes it relatively convenient for storage, transportation, and use.

Molecular weight: The molecular weight range of copolymer petroleum resin is relatively wide, ranging from several hundred to several thousand. The size of the molecular weight will affect its physical properties and processing performance. Generally speaking, resins with higher molecular weight have higher strength and heat resistance, but their processing performance may be slightly inferior; Resins with smaller molecular weights have better processing properties, but their strength and heat resistance may be slightly lower.

5. Other physical properties

Adhesion: Co polymerized petroleum resin has good adhesion, which can improve the water resistance, chemical resistance, and weather resistance of coatings. This makes it have a wide range of application prospects in fields such as coatings and inks.
Stability: It exhibits good stability during storage and use, and is not easily decomposed or deteriorated. This helps ensure the quality and stable performance of copolymer petroleum resin.
Overall, copolymer petroleum resin has a series of excellent physical properties, which have made it widely used in many industrial fields. Whether as a plasticizer for coatings and inks, or as an additive for adhesives and rubber products, copolymer petroleum resin has demonstrated its unique value and charm.
