Description

Isoprene is a fundamental, highly reactive hydrocarbon monomer essential for the synthesis of synthetic rubber and a wide range of elastomers. Its unique conjugated diene structure makes it a critical building block in polymer chemistry, enabling the production of materials with specific elasticity, resilience, and chemical resistance properties. This product is vital for manufacturers in the tire, automotive parts, adhesive, and specialty chemical industries seeking reliable, high-purity raw materials for their production processes.

Application

• Synthetic Rubber Production: The primary use as a monomer for the manufacture of polyisoprene (IR) and styrene-isoprene-styrene (SIS) block copolymers.
• Tire & Automotive Components: A key raw material for high-performance tire treads, sidewalls, and various rubber automotive parts requiring excellent wear and tear resistance.
• Adhesives & Sealants: Used in the formulation of pressure-sensitive adhesives, hot-melt adhesives, and construction sealants due to its tackifying properties.
• Footwear & Sporting Goods: Employed in the production of shoe soles, athletic equipment, and other molded rubber goods.
• Medical & Pharmaceutical: Serves as an intermediate in the synthesis of certain pharmaceuticals and can be used in medical-grade elastomers.
• Chemical Intermediate: Used in organic synthesis for the production of terpenes, flavors, fragrances, and agricultural chemicals.

Quality Control

Our Isoprene is produced and handled under stringent quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing including Gas Chromatography (GC) for assay and impurity profiling. A Certificate of Analysis (COA) detailing purity, specific gravity, inhibitor content (if applicable), and other critical parameters is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile and flammable nature, containers must be kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is below 25°C (77°F).
