N-nitrosodiphenylamine
Description
N-Nitrosodiphenylamine (CAS 86-30-6) is an industrial chemical used primarily as a polymerization inhibitor and retarder in rubber and polymer processing. It controls cure rates and prevents premature vulcanization.
This chemical gives manufacturers greater control over processing windows during production. In rubber compounding, it functions as a prevulcanization inhibitor, delaying the onset of cure during mixing and extrusion.
This delay helps to reduce scorch risk in tire and technical rubber production. Polymer manufacturers use it to stabilize reactive monomer systems during storage and transport, preventing unwanted polymerization.
In plastics processing, it acts as a stabilizer to extend the safe handling window of peroxide-cured compounds. It is also used as an antioxidant additive in certain polymer formulations where degradation is a concern.
N-Nitrosodiphenylamine is typically supplied as a solid in powder or crystalline form. Technical grade is the standard commercial specification for industrial rubber and polymer applications.
It is available in bulk quantities suited to compounding and manufacturing operations. Packaging options range from bags to bulk containers depending on the specific volume requirements of the facility.
