Description

Azacyclotridecan-2-One, Polymer With Oxirane, Block is a specialized block copolymer derived from laurolactam (azacyclotridecan-2-one) and oxirane (ethylene oxide). This engineered polymer is valued for its unique combination of polyamide-like structural integrity and the hydrophilic, surfactant properties imparted by the polyether block. It serves as a critical performance additive and compatibilizer for advanced material formulations across several high-value manufacturing sectors.

Application

• Polymer Modification: Acts as a compatibilizer and impact modifier in polyamide (PA12) blends, improving toughness and processability.
• Surface Coatings & Inks: Used as a dispersing agent and flow control additive to enhance pigment wetting and film formation.
• Adhesives & Sealants: Imparts flexibility and improves adhesion to various substrates in hot-melt and reactive adhesive systems.
• Fiber & Textile Processing: Functions as a spin finish additive and antistatic agent for synthetic fibers.
• Personal Care Formulations: Serves as a non-ionic emulsifier and viscosity modifier in cosmetic and skincare products.
• Industrial Lubricants: Employed as a viscosity index improver and dispersant in synthetic lubricant formulations.
