• Analyst Opinion at Fact.MR
  • Shambhu Nath Jha , Principal Consultant for Polymers & Plastics, opines: 'In my analysis, I have observed that the margin structure of US EPS producers is migrating from volume-dependent packaging economics to specification-driven insulation economics. Manufacturers maintaining legacy foodservice foam capacity in jurisdictions with active ban legislation face stranded asset exposure that compresses return on invested capital. Producers redirecting capacity toward higher-density insulation grades aligned with updated IECC energy code requirements position themselves for stable, code-mandated demand that is less exposed to municipal packaging restrictions.'
