HTPA Flowing Agent F-S2500

F-S2500 is a novel flowing agent specially developed for high temperature polyamide (HTPA). F-S2500 has excellent thermal stability and good compatibility with HTPA. Adding 1%, the flowability is significantly improved, while maintaining good mechanical and thermal properties.

1. Materials
