poly(m-phenylene isophthalamide)

polymer

Poly(m-phenylene isophthalamide) is an aromatic polyamide (aramid) synthesized from m-phenylenediamine and isophthaloyl chloride, combining rigid aromatic backbone chemistry with specific regiochemistry to achieve distinct thermal and mechanical properties compared to other aramids. This material serves aerospace, automotive, and electrical applications where high-temperature stability and flame resistance are critical, particularly in insulation systems, composite matrices, and protective textiles; it bridges the gap between conventional polyamides and ultra-high-performance aramids, offering a balance of processability and performance in demanding thermal environments.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
