Description

Resins, Polyterpene CAS NO 68917-67-9 are a class of thermoplastic polymers derived from terpene hydrocarbons, primarily β-pinene, valued for their excellent tackifying properties, light color, and good thermal stability. These resins are crucial for enhancing adhesion, cohesion, and viscosity control in a wide range of industrial formulations. They are essential raw materials for manufacturers in the adhesive, sealant, rubber, and coating industries seeking high-performance, naturally-derived modifiers.

Application

• Hot-Melt Adhesives (HMAs): A primary tackifier providing excellent initial grab, adhesion to non-polar surfaces, and low odor.
• Pressure-Sensitive Adhesives (PSAs): Used in tapes and labels to balance tack, peel adhesion, and shear strength.
• Rubber Compounding: Acts as a processing aid and reinforcing agent in tires, belts, and other rubber goods.
• Sealants and Caulks: Improves adhesion, flexibility, and durability in construction and automotive sealants.
• Industrial and Protective Coatings: Enhances gloss, hardness, and water resistance in various coating formulations.
• Printing Inks: Used as a resinous component to improve gloss, rub resistance, and pigment wetting.
• Chewing Gum Base: Serves as a masticatory substance in food-grade applications (subject to specific purity grades).

Quality Control

Our Polyterpene Resins are manufactured under a strict quality management system. Each batch is tested against key parameters including softening point, color, acid value, and solubility to ensure consistent performance and reliable supply. Certificates of Analysis (COA) are provided with every shipment. We can support compliance with relevant standards for industrial, adhesive, and specific food-contact applications upon request.

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. For long-term storage, maintaining a consistent temperature is recommended to preserve product properties.
