Application

4,4 '- Azobis (4-cyanovaleric acid) is used as an initiator, and 4,4' - Azobis (4-cyanovaleric acid) polymer is synthesized as a free radical initiator. 4,4 '- Azobis (4-cyanovaleric acid) can also be used as a foaming agent for plastics and synthetic rubber.

Features

I. Core triggering performance: Strong controllability, adaptable to precise aggregation requirements

Excellent thermal decomposition characteristics (core advantage)

4 4 Azobis 4-Cyano Valeric Acid has strong water solubility and system compatibility

II. Physical, chemical and process characteristics: Suitable for industrial production

Physical form is easy to handle: CAS 2638-94-0 4 4 Azobis 4-cyano Valeric Acid is a white crystalline powder at room temperature, with good fluidity, easy to measure and disperse, and no risk of moisture absorption and caking (strong stability under normal storage conditions), which is convenient for feeding and mixing in industrial production;

Controllable thermal stability: 4 4 Azobis 4-cyano Valeric Acid is stable when stored at room temperature and away from light. It will decompose rapidly only above 100℃. No extreme low-temperature conditions are required during transportation and storage (different from low-temperature active initiators), reducing logistics costs.

No metal residue: The synthesis process does not require metal catalysts. The CAS 2638-94-0 product has a high purity (industrial grade purity ≥98%, high-end grade ≥99%), free of heavy metal impurities. CAS 2638-94-0 meets the low impurity requirements for environmental protection and electronic materials.
