Description
N,N′-Bis(2,6-diisopropylphenyl)carbodiimide (CAS 2162-74-5) is a sterically hindered carbodiimide stabilizer commercially known under trade names including Stabaxol I, Stabaxol 1, and HRstab-409. It carries EC number 218-487-5 and falls under HS code 29213000. No E-code designation applies to this substance.
In polymer processing, it functions as a hydrolysis stabilizer by reacting with carboxylic acid end groups in polyesters and polyurethanes, interrupting chain scission triggered by moisture and heat. This mechanism extends service life in automotive components and engineering plastics exposed to humid or thermally aggressive environments. It is also employed in lubricant formulations to control acid buildup.
The material is supplied as a powder to lump solid and is subject to REACH registration requirements within the European Economic Area. Procurement teams should confirm supplier SDS documentation and lot-specific purity data. Standard industrial packaging applies; consult your supplier for available pack sizes and lead times.
