1. What raw materials are used for meltblown nonwoven fabric, and where do supply chain risks lie?
Meltblown lines convert polypropylene, polyester, and specialty polymers into microfibers. Polypropylene accounts for roughly 72% of resin volume, with most capacity in Asia Pacific. Disruptions in propylene monomer pricing, polymer import licensing, or logistics can quickly change meltblown fabric production costs.
