Azobisisobutyronitrile
Azobisisobutyronitrile (AIBN) is a white crystalline chemical compound with the molecular formula C8H12N4, supplied by Zibo Defeng Chemical Co.,Ltd. as a technical-grade free radical initiator. It has a minimum purity of 98% and is primarily used in vinyl polymerization processes, including the production of PVC, acrylic resins, and polyolefins. The material decomposes upon heating to release free radicals, with a half-life of approximately 10 hours at 65°C, making it ideal for batch and suspension polymerization in industrial settings.
This grade of AIBN is stable under controlled conditions and is typically packed in 25kg fiber drums for safe international transport. The compound is a standard thermal initiator in the plastics and coatings industries, where it catalyzes reactions to produce durable and lightweight materials. Industry-standard applications include its use in adhesives, coatings, and advanced composites, where its ability to initiate polymerization at moderate temperatures is critical.
Polymer manufacturers and coating producers source AIBN for bulk import due to its reliability in high-volume production. The product is traded globally, with typical storage requirements including cool, dry conditions to maintain its shelf life. Buyers should confirm packaging options, as the supplier offers standardized 25kg units, and verify compliance with international safety standards for handling and shipping.
