PEMA

polymer

PEMA is a high-performance engineering polymer belonging to the polyetherimide (PEI) or similar high-temperature thermoplastic family, designed to maintain mechanical properties across elevated temperature ranges. It finds use in aerospace, automotive, and electronic applications where thermal stability, dimensional consistency, and moderate stiffness are required simultaneously—competing directly with polyetherimide (ULTEM) and polysulfone (PSU) where cost-performance balance or specific processing advantages matter.

Regulatory Screening

Environmental

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.
