AI Technical Summary

Technical Problem

Existing technologies struggle to maintain the melt strength of Nylon 12 while improving its melt flowability and reducing its precipitation, leading to processing difficulties and unstable performance.

Method used

By introducing a hydrogen bond modifier into nylon 12 resin, it forms new hydrogen bonds with the amide groups of nylon 12 resin, competitively dissociates intermolecular hydrogen bonds, improves melt flowability, and provides strain hardening by reassociation at low strain rates. At the same time, it is combined with plasticizers, toughening agents and other additives to optimize material properties.

Benefits of technology

It achieves good melt flowability, high melt strength and low precipitation of nylon 12 material, making it suitable for a variety of extruded products and improving processing efficiency and long-term stability.
