As one of the world's top specialists in hydrazine hydrate and its derivatives, Arkema provides Azo-initiators that are safe and easy to use in free radical polymerization processes guaranteeing quality products delivered to you on time.

AZDN: Azo-bis-isobutyronitrile

Properties

Sold in powder or granular form, these products provide the following benefits:

Better control of polymerization: implementation temperature of 45 to 100°C, linear polymer, high molecular weight, narrow molecular weight distribution, no cross-linking, little or no branching, no “eye-fishing” guaranteeing transparency etc.
No oxygenated or hydrogenated residues: slower ageing of polymers, stability of pigmented or dyed polymer systems

(Note that AZDN must be transported and stocked at a temperature below 15° C).

Markets and applications

Free-radical polymerization
Azo-initiators are mainly used in polymerization reactions to initiate or terminate the polymerization process, or to reduce the residual monomer content. Their possible applications thus cover many fields: acrylic glass sheets, flocculants, acrylic fibers, paints and coating resins, grafted polyols etc.

Free radical synthesis
Azo-initiators are also used as catalysts for free radical halogenation, sulphochlorination, addition of phosphorus applied for the manufacture of agrochemicals, pharmaceuticals and solvent extraction reagents.

Blowing agent
AZDN is used as a low temperature chemical blowing agent for pressure blown PVC and silicone rubber. End applications include wind turbine blades, isolation panels, flotation devices, boat structures and seat foams etc.
