Product introduction

Poly sulfonamide (PSA) is an aromatic polyamide fiber. Its macromolecular structure is creatively introduced in the p-benzene ring and sulfone structure, so that the strong-absorbing electron sulfone group (-SO2-) through the benzene ring double bond conjugated system to reduce the electron cloud density of nitrogen atoms on the amide group, thereby obtaining outstanding heat resistance, flame resistance.

The cross-section of the aramid fiber is an approximately elliptical “bean type”, which increases the specific surface area by 17% compared to the circular section.
