What is EPS 200?
EPS 200 is a high-strength EN 13163 expanded polystyrene grade rated at 200 kPa compressive strength, with nominal density 0.032 g/cm³ (32 kg/m³) and thermal conductivity 0.033 W/m·K. It is used for heavy floor loads and geofoam fills, and is supplied as flame-retardant board, grey graphite board, non-FR stock, geofoam blocks and shape-moulded parts. Maximum service temperature is 80 °C, and UV, solvents and non-certified bitumen or PU coatings will damage it. EPS 150 covers lighter load cases; XPS 300 is the alternative where moisture exposure or below-grade service dominates. EPS 200 has a density of 0.03 g/cm³ (0.0012 lb/in³), lighter than 93% of polymer grades. Its glass-transition temperature is 100°C (212 °F). EPS 200 has a tensile strength of 0.45 MPa (0.0653 ksi), weaker than 90% of polymer grades. Elongation at break is 5% and the elastic modulus is 0.01 GPa (0.0015 Msi).

Chemical & Environmental3
Corrosion resistance is excellent (85/100), better than 65% of polymer grades. UV resistance is poor.
Sustainability4
Producing a kilogram of EPS 200 takes about 105 MJ of energy and emits 3.5 kg of CO₂ — more than 54% of polymer grades. Typical recycled content is 8%.
Manufacturability4
EPS 200's machinability is excellent (90/100, better than 95% of polymer grades); weldability poor (30/100); formability good (55/100).

Working with EPS 200
Is EPS 200 easy to machine?
Hot-wire or band-saw cuts cleanly with negligible dust; routing and CNC hot-wire shaping work well but avoid high-speed steel tools that smear the cell walls.
Can EPS 200 be welded?
No true welding — join by hot-air/hot-plate fusion of contacting faces, or bond with EPS-safe water-based/PU adhesives (never solvent-based).
Can EPS 200 be formed, bent or molded?
Produced by pentane pre-expansion of PS beads, ageing, then steam block or shape moulding at ~0.5–1.0 bar steam; boards are cut from aged block after 3–7 days dimensional stabilisation.
EPS 200 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)n-/iso-pentane, largely lost during ageing | 0.2 – 2 | 0.8 |

What surface finishes work on EPS 200?
Accepts cement- or polymer-modified renders, mesh-reinforced EIFS coats and water-based paints; requires UV protection and a solvent-free primer, and any bitumen or PU coating must be certified EPS-compatible.

EPS 200 — frequently asked
What is EPS 200 used for?
EPS 200 is typically used for heavy floor insulation, geofoam fill and industrial flooring. In short: highest-strength EPS class here; 200 kPa load capability; geofoam and industrial floors.
What is the tensile strength of EPS 200?
EPS 200 has a typical tensile strength of 0.45 MPa (0.0653 ksi) — weaker than 90% of polymer grades. Strength varies by condition: see the 4 listed tempers.
Is EPS 200 easy to machine?
Yes — machinability is rated excellent (90/100, better than 95% of polymer grades). Hot-wire or band-saw cuts cleanly with negligible dust; routing and CNC hot-wire shaping work well but avoid high-speed steel tools that smear the cell walls.
Can EPS 200 be welded?
Not readily — weldability is rated poor (30/100). No true welding — join by hot-air/hot-plate fusion of contacting faces, or bond with EPS-safe water-based/PU adhesives (never solvent-based).
What surface finishes work on EPS 200?
Accepts cement- or polymer-modified renders, mesh-reinforced EIFS coats and water-based paints; requires UV protection and a solvent-free primer, and any bitumen or PU coating must be certified EPS-compatible.

What is the maximum service temperature of EPS 200?
EPS 200 is rated for continuous use to about 80°C (176 °F), and briefly to 100°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
How much does EPS 200 cost?
