Thermal Polymerization Petroleum Resin

The water resistance of thermal polymerization petroleum resin mainly depends on its specific chemical structure, preparation process, and application requirements. Generally speaking, thermal polymerization petroleum resin can exhibit good water resistance after appropriate treatment and modification.

Hot polymerized petroleum resin is prepared by polymerization reaction of C9 fraction and other raw materials at high temperature. Its molecular structure usually does not contain polar or functional groups, so it has certain chemical stability. This stability enables the thermal polymerization petroleum resin to maintain its performance stability in humid environments and is less prone to hydrolysis or degradation reactions.

However, it should be noted that the water resistance of thermal polymerization petroleum resin may be affected by factors such as its molecular structure, softening point, and color number. For example, thermoplastic resins with higher softening points may have better water resistance because their molecular chains are longer and have higher cross-linking, making them more difficult to penetrate and break by water molecules. Meanwhile, lighter colored thermoplastic resins may also have better water resistance because they contain fewer impurities and unreacted monomers, and are less sensitive to water molecules.
In practical applications, measures such as adding water-resistant agents and surface treatment can be taken to improve the water resistance of thermal polymerization petroleum resin. These measures can further enhance the waterproof performance of thermal polymerization petroleum resin and meet its application needs in fields such as coatings, adhesives, and rubber.
Overall, after appropriate treatment and modification, thermal polymerization petroleum resin can exhibit good water resistance. However, the specific performance still needs to be evaluated and selected based on its chemical structure, preparation process, and the requirements of the application field.
