What is EPS 100 NON-FR?
EPS 100 NON-FR is EPS 100 in the NON-FR grade — only for packaging, void formers and civil fill where no reaction-to-fire class is required. EPS 100 NON-FR has a tensile strength of 0.25 MPa (0.0363 ksi), weaker than 95% of polymer grades. Elongation at break is 1.8% and the elastic modulus is 0.01 GPa (9.43×10⁻⁴ Msi). EPS 100 NON-FR has a density of 0.02 g/cm³ (7.59×10⁻⁴ lb/in³), lighter than 97% of polymer grades. Its glass-transition temperature is 100°C (212 °F). WHITE-FR is the default condition FabDigit quotes; NON-FR is available on request or by drawing note.

Working with EPS 100 NON-FR
Is EPS 100 easy to machine?
Cut with hot wire, fine-tooth band saw or CNC router at high feed; use dust/static extraction and avoid solvent-based coolants.
Can EPS 100 be welded?
No fusion welding — join with hot-plate/steam fusion in the mould or with water-based/EPS-safe adhesives and mechanical fixings.
Can EPS 100 be formed, bent or molded?
Made by pre-expanding EPS beads with steam (~100–110 °C), ageing, then block or shape moulding at 0.6–1.0 bar steam; drying and 3–7 day ageing needed before cutting to control shrinkage.
What surface finishes work on EPS 100?
Compatible with cement/polymer-modified renders, EIFS mesh coats and water-based paints; never use solvent-based bitumen, petrol-thinned primers or PU with high solvent load.
EPS 100 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| pentane (residual blowing agent)decays after ageing; fire precaution during storage of fresh beads | 0.1 – 1.5 | 0.5 |
| polymeric brominated flame retardant (PoFR construction grades only; replaced HBCD in EU since 2015 | 0.3 – 1.2 | 0.7 |
| graphite (IR absorber)grey/graphite-enhanced variant only | 0 – 4 | 2 |
| processing additives (nucleant, antistat | 0 – 0.5 | 0.2 |
| polystyrene (styrene homopolymer)solid phase; foam is ~97–98 vol % air | ≥ 94 (balance) | — |
EPS 100 NON-FR — frequently asked
What is EPS 100 NON-FR used for?
EPS 100 NON-FR is typically used for floor insulation, flat roof insulation and light traffic areas. In short: standard floor-insulation EPS; 100 kPa load class; grey graphite option available.
What is the tensile strength of EPS 100 NON-FR?
EPS 100 NON-FR has a typical tensile strength of 0.25 MPa (0.0363 ksi) — weaker than 95% of polymer grades. Strength varies by condition: see the 3 listed tempers.
Is EPS 100 NON-FR easy to machine?
Yes — machinability is rated excellent (95/100, better than 100% of polymer grades). Cut with hot wire, fine-tooth band saw or CNC router at high feed; use dust/static extraction and avoid solvent-based coolants.
