Non-FR-S is black graphite EPS produced through extrusion using polystyrene as the base resin. Natural flake graphite improves insulation performance without flame-retardant additives. It is intended for applications that do not require a fire-rating classification.
Non-FR-S graphite EPS is intended for projects that do not require a fire-rating classification. It offers graphite-enhanced thermal insulation in a formulation without flame-retardant additives.
The material is produced through extrusion with natural flake graphite added to polystyrene. NFR-S101 to NFR-S401 cover bead sizes from 1.00–1.80 mm down to 0.30–0.80 mm, with listed thermal conductivity of 0.030–0.034 W/m·K.
| Grade | Application / positioning | Molded density (kg/m³) | Bead size (mm) | Thermal conductivity λ (W/m·K) |
|---|---|---|---|---|
| NFR-S101 | Non-FR Graphite GP | 15–25 | 1.00–1.80 | 0.030–0.034 |
| NFR-S201 | Non-FR Graphite Medium | 18–28 | 0.80–1.30 | 0.030–0.034 |
| NFR-S301 | Non-FR Graphite Fine-Bead | 20–32 | 0.60–1.00 | 0.030–0.034 |
| NFR-S401 | Non-FR Graphite Micro HD | 25–35 | 0.30–0.80 | 0.030–0.034 |
Include the NFR-S code, target density, bead-size requirement, intended use and order quantity. Make clear that the application accepts a non-flame-retardant material.
