Widely Used Polymerization Initiator

AIBN serves as a highly effective initiator for the polymerization of vinyl monomers, making it essential in the production of various plastics and synthetic rubbers. Its reliable and consistent decomposition produces free radicals critical for industrial-scale polymerization processes.

Safe Storage and Handling Guidelines

Due to its sensitivity to heat, friction, and moisture, AIBN should always be stored in a cool, dry place, away from direct light. Handling should occur under a dry protective atmosphere, and containers should remain tightly sealed to maintain its stability and extend shelf life.

Packaging Options and Quality Assurance

AIBN is packaged in moisture-resistant containers, available in 1kg, 5kg, or 25kg units, to protect the product during storage and transportation. With a purity of 98%, it meets industrial-grade standards and ensures reliable performance for manufacturers and suppliers alike.

FAQs of 2, 2-Azobis (2-methylpropionitrile) CAS 78-67-1:

Q: How should 2,2-Azobis(2-methylpropionitrile) be stored to ensure maximum shelf life?

A: To maintain its stability and 12-month shelf life, AIBN must be stored in a cool, dry, and well-ventilated area, away from heat sources and direct sunlight. Keep the product sealed in its original moisture-resistant container.

Q: What is the primary use of AIBN in industrial applications?

A: AIBN is mainly used as a free-radical initiator in the polymerization of vinyl monomers, which is vital for manufacturing plastics and synthetic rubbers. It also acts as a blowing agent in plastic and rubber industries.

Q: When does AIBN decompose, and what precautions should be observed during handling?

A: AIBN begins to decompose at temperatures between 65C and 70C, releasing nitrogen gas. To prevent accidental decomposition, avoid subjecting it to heat, friction, or open flames, and always handle the substance under a dry protective atmosphere.

Q: Where can AIBN be purchased in bulk quantities?

A: AIBN can be obtained from chemical distributors, exporters, manufacturers, and suppliers, particularly in China, and is available in bulk packaging options of 1kg, 5kg, and 25kg.

Q: What benefits does AIBN offer over other polymerization initiators?

A: AIBN provides consistent, controlled free-radical generation at relatively low temperatures, ensuring efficient polymerization with minimal side reactions and offering versatility through its solubility in a range of organic solvents.

Q: How is AIBN classified and what is its chemical identity?

A: AIBN is classified as an azo compound and organic peroxide, with the chemical name 2,2-Azobis(2-methylpropionitrile), CAS number 78-67-1, and molecular formula C8H12N4.
