Eastman Chemical Company

What helps: (1) Intangible assets and brands: Tritan copolyesters, Saflex PVB interlayers, and LLumar/SunTek/V‑Kool films are recognized by OEMs, architects and installers. Eastman reports a large IP estate (700+ US patents, 1,600+ foreign, 4,500+ trademarks), and application know‑how ties to customer qualification.

Score 65/100, weight 25%. (2) Switching costs: In engineered polymers, interlayers and films, certifications, tooling, and optical/acoustic specs create moderate frictions; aftermarket film dealer networks also add relationship stickiness.

Score 60/100, weight 25%. (3) Cost advantages: Integration into acetyls/olefins, a massive Kingsport site, and in‑house feedstock improve logistics and yields, but are partly offset by energy and commodity exposure.

Score 55/100, weight 20%. (4) Efficient scale: Niche leadership in PVB interlayers and window films benefits from scale in production and distribution; chemical recycling plants may add scale barriers as they mature. Score 60/100, weight 20%. (5) Network effects: Limited; some indirect effects via installer networks and brand visibility.

Score 10/100, weight 10%. Weighted average ≈ 58. Key erosion risks: Asian competition in intermediates, policy shifts on recycling accounting, and end‑market substitution.
