Description

Petroleum Resins, Hydrogenated are high-performance, low-color hydrocarbon polymers derived from petroleum feedstocks and subsequently hydrogenated to enhance their stability and performance characteristics. This process significantly improves their resistance to oxidation, heat, and UV light, making them a superior choice for applications requiring long-term durability and color stability. These resins are essential for formulators and manufacturers in the adhesives, sealants, coatings, and rubber compounding industries seeking to improve product performance and longevity.

Application

• Hot Melt Adhesives (HMA): Acts as a key tackifier, providing excellent adhesion, thermal stability, and low odor for packaging, non-woven, and assembly applications.
• Pressure-Sensitive Adhesives (PSA): Used in tapes and labels to enhance tack, peel strength, and shear resistance while maintaining good color and aging properties.
• Rubber Compounding: Improves the processing, tack, and reinforcement of synthetic rubbers like SIS, SBS, and EPDM in products such as tires, belts, and footwear.
• Industrial & Protective Coatings: Imparts water resistance, hardness, and improved drying characteristics in road marking paints, marine coatings, and industrial finishes.
• Sealants & Caulks: Enhances flexibility, adhesion, and weather resistance in construction and automotive sealant formulations.
• Printing Inks: Serves as a resinous component to improve gloss, rub resistance, and pigment wetting, particularly in gravure and flexographic inks.
• Polymer Modification: Used as a compatibilizer or processing aid to modify the properties of various plastics and elastomers.

Quality Control

Our hydrogenated petroleum resins are manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. Each lot undergoes rigorous testing for key parameters including color, softening point, bromine number, and ash content. Certificates of Analysis (COA) are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. Under these conditions, the product is stable for extended periods.
