Bis(2,6-diisopropylphenyl)carbodiimide
Description
Bis(2,6-diisopropylphenyl)carbodiimide (CAS 2162-74-5), commercially known as Staboxol 1, is a monomeric carbodiimide stabilizer used to protect polymers and lubricant formulations from hydrolytic degradation. It reacts with carboxylic acid groups generated during polymer breakdown, interrupting chain scission before it causes measurable property loss. In polyester, polyurethane, and polylactic acid compounds, it extends service life.
By neutralizing acidic degradation products that would otherwise accelerate molecular weight loss, it ensures material integrity. Lubricant and metalworking fluid formulators incorporate it to maintain viscosity stability. It protects ester-based base oils under high-temperature or moisture-exposed operating conditions. Automotive under-hood components, including seals, gaskets, and engineering plastic parts, benefit from its inclusion.
Where thermal and hydrolytic stress would otherwise shorten part lifespan, this stabilizer provides essential protection. It is also used in film and fiber processing where maintaining melt viscosity consistency is a requirement. Ensuring quality across production runs is a direct result of its chemical properties. Bis(2,6-diisopropylphenyl)carbodiimide is supplied as a white to off-white powder or solid for industrial use.
Technical and polymer-stabilizer grades are the standard commercial forms available from specialty chemical suppliers. Packaging typically ranges from kilogram-scale laboratory quantities to multi-kilogram industrial lots.
