Triisopropylbenzene polycarbodiimide

Triisopropylbenzene polycarbodiimide (CAS 29117-01-9), commercially known as Stabaxol P 100, is a polymeric carbodiimide stabilizer that protects hydrolysis-sensitive polymers from acid-catalyzed degradation.

Where is Triisopropylbenzene polycarbodiimide used?

• Engineering plastics, elastomers and coatings: reacts with carboxylic acid end groups from polymer hydrolysis, extending service life in demanding environments
• Polyester and polyurethane compounding: hydrolysis stabilizer that scavenges free acid groups, preventing molecular weight loss during processing or long-term use
• Thermoplastic polyurethane and polylactic acid compounds: incorporated by rubber and elastomer formulators where moisture exposure would otherwise accelerate chain scission
• Waterborne coatings and adhesives: crosslinker for carboxyl-functional resins, improving film durability and chemical resistance
• In fiber and film production it maintains mechanical performance under humid or elevated-temperature conditions.

Commercial specifications

• Technical grade; specifications typically defined by carbodiimide equivalent weight and residual isocyanate content
