Description

Distillates (Petroleum), C3-6, Piperylene-Rich, Polymers With Styrene is a specialized hydrocarbon resin derived from a C3-6 petroleum distillate fraction rich in piperylene and copolymerized with styrene. This product matters as a high-performance tackifier and modifier, offering excellent compatibility, thermal stability, and adhesion properties for demanding formulations. It is primarily needed by manufacturers in the adhesive, sealant, rubber compounding, and coating industries seeking to enhance product performance and processing characteristics.

Application

• Pressure-Sensitive Adhesives (PSAs): Acts as a key tackifying resin for labels, tapes, and graphic films.
• Hot-Melt Adhesives: Improves wetting, open time, and bond strength in packaging and assembly applications.
• Rubber Compounding: Used as a processing aid and reinforcing agent in tire and industrial rubber goods.
• Industrial and Protective Coatings: Enhances hardness, water resistance, and drying properties.
• Sealants and Caulks: Improves flexibility, adhesion, and durability.
• Printing Inks: Modifies rheology and improves gloss and pigment wetting.
• Asphalt Modification: Used to improve the temperature susceptibility and durability of paving materials.

Quality Control

Our hydrocarbon resins are manufactured under strict process controls to ensure batch-to-batch consistency and performance reliability. Quality is verified through a comprehensive suite of tests including softening point, color, acid value, and bromine number. Certificates of Analysis (COA) detailing all relevant specifications are provided with every shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperatures (typically 15-25°C). Keep away from heat sources and open flame. For long-term storage, an inert gas blanket (e.g., nitrogen) is recommended to prevent oxidation and maintain product color stability.
