Description

Polybutene is a synthetic hydrocarbon polymer derived from the polymerization of butene, known for its excellent tackifying, adhesive, and water-resistant properties. This versatile material is valued for its ability to modify the viscosity and performance characteristics of various formulations. It is essential for manufacturers in the adhesives, sealants, lubricants, and personal care industries seeking to enhance product performance and durability.

Application

• Adhesives & Sealants: Acts as a key tackifier and viscosity modifier in hot-melt, pressure-sensitive, and construction adhesives.
• Lubricants & Greases: Used as a thickener and performance additive to improve viscosity index and film strength.
• Polymer Modification: Employed as a plasticizer and compatibilizer in rubber, plastics (like polypropylene and polyethylene), and elastomers to enhance flexibility and processability.
• Personal Care & Cosmetics: Functions as a film-forming agent, emollient, and viscosity controller in products like lipsticks, hair gels, and creams.
• Caulks & Mastics: Provides non-drying, permanent flexibility and adhesion in sealant formulations for construction and automotive applications.
• Electrical Insulation: Used in cable-filling compounds and insulating tapes due to its excellent dielectric properties and moisture resistance.
• Fuel & Lubricant Additives: Serves as a carrier fluid and detergent in two-stroke engine oils and industrial lubricant packages.
• Chewing Gum Base: Approved for use as a masticatory substance in chewing gum formulations, providing the desired chew texture.

Quality Control

Our Polybutene is manufactured under a stringent quality management system. Each batch is tested against critical parameters including viscosity, molecular weight distribution, and color to ensure consistency and performance. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing the specifications for the supplied grade. Our production adheres to relevant industry standards, and we can support compliance needs for applications in food contact (where applicable) and regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C / 59-77°F). Keep away from heat, sparks, and open flame. For long-term storage, blanketing with an inert gas such as nitrogen is recommended to prevent oxidation.
