Description

N,N'-Methylenebisdodecanamide is a high-purity, synthetic bisamide compound with the CAS number 5136-45-8. This specialty chemical serves as a highly effective slip agent, internal lubricant, and anti-blocking agent, significantly improving the processing and surface properties of polymer systems. It is essential for manufacturers in the plastics, coatings, and adhesives industries seeking to enhance product performance and production efficiency.

Application

• Polymer Processing Aid: Acts as a primary internal lubricant and slip agent in polyolefin films (e.g., LDPE, HDPE, PP) to reduce friction and improve machinability.
• Anti-blocking Agent: Prevents film layers from adhering to each other during storage and transport, crucial for packaging films.
• Surface Modifier: Imparts a smooth, low-friction surface finish to molded plastic parts and extruded profiles.
• Release Agent: Used in compounding to facilitate the release of plastic products from molds, increasing production speed.
• Additive for Masterbatches: A key component in additive concentrates for uniform dispersion in final polymer matrices.
• Specialty Coatings and Inks: Enhances rub resistance and provides a smooth feel in specific coating formulations.
