PAN
polymerPAN (polyacrylonitrile) is a synthetic acrylic polymer known for its high strength, rigidity, and thermal stability, commonly processed into fibers and films. It is widely used as a precursor material for carbon fiber production, as well as in acrylic fibers for textiles, filtration membranes, and protective coatings where chemical resistance and dimensional stability are required. Engineers select PAN-based materials for applications demanding lightweight strength combined with thermal performance and resistance to solvents and UV degradation, particularly in composites, aerospace, and industrial filtration.

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.
