Trade Name → Polymer → Fungal Resistance Lookup

Cross-reference of 246 plastic and elastomer trade and generic names — spanning fluoropolymers, polyimides, engineering thermoplastics, and common elastomer families — to their base polymer chemistry and typical fungal resistance rating, per MIL-HDBK-454B (Guideline 4, Group I / Group II), MIL-STD-810 Method 508 (28-day fungus exposure), and ASTM G21 (0–4 rating scale).

Search by trade name, owner, polymer, or abbreviation; filter by material type or resistance category; and click any column header to sort. Ratings are typical for virgin, unfilled material — plasticizers, cellulosic fillers, and some colorants are the actual fungal food source, so a filled or plasticized grade of a "Resistant" material can still support growth. See the legend at left and the footnotes below the table for important caveats.

Rating Scale & Sources
CategoryMeaning
ResistantBase polymer is a non-nutrient; no/negligible growth. Fungus rating 0–1 (ASTM G21 / MIL-STD-810).
ConditionalDepends on grade, filler, plasticizer, or blend phase; verify by test. Typical rating ~1–3.
SusceptibleSupports fungal growth (nutrient); MIL-HDBK-454 Group II or nutrient chemistry. Rating 2–4.

Elastomer rating values are the supplied typical family ratings; plastic rating values are typical ranges inferred from the resistance category, not per-compound test data.

Important Notices
  • Family/typical ratings, not per-compound test data. Ratings reflect the typical resistance of the base polymer family. Fillers, plasticizers, colorants, and specific compounding can shift an individual grade's actual fungal resistance — e.g. NBR compounds have been reported ranging from 0 to 4 depending on formulation.
  • Verify before use. In critical applications, resistance should be confirmed by ASTM G21 or MIL-STD-810 Method 508 testing of the specific compound and grade rather than relying on the family rating alone.
