polyacrylonitrile

polymer

Polyacrylonitrile (PAN) is a synthetic acrylic polymer known for its strong fiber-forming capability and chemical resistance. It is widely used in textile applications—particularly acrylic fibers for apparel and home goods—as well as in composite reinforcement, carbon fiber precursors, and industrial membranes. Engineers select PAN for applications demanding good mechanical strength, thermal stability, and resistance to oils, solvents, and weathering, making it a cost-effective alternative to natural fibers and other synthetic polymers in many commodity and advanced applications.

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.
