Description

Buta-1,3-Diene CAS NO 25339-57-5 is a fundamental conjugated diene hydrocarbon, serving as a critical monomer in the global petrochemical industry. Its primary value lies in its exceptional reactivity, making it the principal building block for a vast array of synthetic rubbers and polymers. This essential chemical is a cornerstone material for manufacturers in the automotive, consumer goods, and specialty chemical sectors seeking to produce high-performance elastomers and plastics.

Application

• Synthetic Rubber Production: The predominant use, serving as the monomer for Styrene-Butadiene Rubber (SBR), Polybutadiene Rubber (BR), and Acrylonitrile Butadiene Styrene (ABS) resins.
• Polymer & Plastics Manufacturing: A key component in the synthesis of various copolymers, including Nitrile Rubber (NBR) and thermoplastic elastomers.
• Chemical Intermediate: Used in the production of other important chemicals such as adiponitrile, a precursor to nylon 6,6.
• Adhesive & Sealant Formulations: Imparts flexibility and tack to industrial and construction adhesives.
• Tire & Automotive Parts: Essential for manufacturing tires, hoses, belts, and other rubber components requiring durability and resilience.
• Footwear & Consumer Products: Used in the soles of shoes and various molded rubber goods.

Quality Control

Our Buta-1,3-Diene is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and reliability for industrial processes. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as purity, inhibitor content, and impurity profiles. Our commitment to supply chain integrity and regulatory compliance (including REACH) ensures you receive a product that meets your exacting specifications.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and flammable nature, store under cool, well-ventilated conditions away from heat, sparks, and open flames. It is typically stored as a liquefied gas under pressure with appropriate stabilizer (inhibitor) to prevent hazardous polymerization. Keep container tightly sealed and upright.
