XPS200 grades and fills
XPS200 is supplied in 4 conditions, soft to hard.
Compare all 4 grades and fillsHide
| Grade · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness |
|---|---|---|---|---|---|
CO₂-blown, HFC-free grade | Use the CO₂/HFO-blown board to meet environmental and green building material requirements in place of HCFC/HFC blowing agents, accepting slightly higher long-term conductivity of 0.032 W/m·K. | — | 0.4 | 2.5 | — |
/ | Choose the graphite-modified grey board when the insulation layer must stay thin: infrared absorbers reduce radiant heat transfer, giving 0.027 W/m·K at the same thickness. | — | 0.42 | 2.2 | — |
GB 8624 B1B-s1,d0 | Use where fire acceptance applies, such as external wall insulation systems; the flame-retardant formulation meets GB 8624 B1 (B-s1,d0) at a density of 32 kg/m³. | — | 0.43 | 2.5 | — |
/ | Choose the underfloor-heating board with foil facing or moulded studs for radiant floor screed layers, prioritising compressive load capacity and long-term dimensional stability up to 70 °C. | — | 0.45 | 2.5 | — |

What is XPS200?
GB/T 10801.2 XPS200 is an extruded closed-cell polystyrene board rated at 200 kPa compressive strength, with a thermal conductivity of 0.030 W/m·K and a maximum service temperature of 75 °C. Engineers use it where insulation is loaded or exposed to moisture — wall and roof boards, floors and below-grade work — in plain, grooved, graphite-loaded, CO2-blown and floor-grade versions, with B1 fire classification available. The extrusion skin must be removed or roughened before bonding, and the board cannot be bent or thermoformed on site. Higher-strength XPS classes are the step up for heavy floor loads. XPS200 has a density of 0.03 g/cm³ (0.0011 lb/in³), lighter than 94% of polymer grades. Its glass-transition temperature is 100°C (212 °F). XPS200 has a tensile strength of 0.45 MPa (0.0653 ksi), weaker than 90% of polymer grades. The elastic modulus is 0.01 GPa (0.0017 Msi).

Working with XPS200
Is XPS200 easy to machine?
Hot-wire cutting or a fine-tooth band saw or circular saw is sufficient; keep feed fast to avoid melted edges. CNC routing can produce profiles but needs dust extraction, as the static-charged chips scatter easily.
Can XPS200 be welded?
Not fusion welded. Close board joints with dedicated polyurethane foam adhesive or water-based adhesive, or lap and stagger the joints; solvent-based adhesives must not be used.
Can XPS200 be formed, bent or molded?
Produced by extrusion foaming (extruder with blowing-agent injection and sizing rolls) as rigid board. On site it can only be cut — no cold bending or thermoforming.
XPS200 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 |
|---|---|---|
| blowing agent residue (CO2 / HFO / HFC)gas in closed cells, partly replaced by air over time | 1 – 4 | 2.5 |
| flame retardant (polymeric brominated / upper end of range for fire class B1 | 0.5 – 3 | 1.5 |

What surface finishes work on XPS200?
The extrusion skin must be planed off and the surface grooved, scratched or treated with a bonding primer before plaster or adhesive is applied. The finished surface must be covered with render mortar, cement board or a coating to prevent UV aging and flame contact.

XPS200 — frequently asked
What is XPS200 used for?
XPS200 is typically used for exterior wall insulation boards, inverted (protected membrane) roof insulation, underfloor heating and floor screed insulation, foundation and below-grade wall insulation, cold storage floor insulation and road and railway frost protection layers. In short: 200 kPa XPS board; load-bearing XPS grade; lower conductivity than EPS.
What is the tensile strength of XPS200?
XPS200 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 XPS200 easy to machine?
Yes — machinability is rated excellent (85/100, better than 88% of polymer grades). Hot-wire cutting or a fine-tooth band saw or circular saw is sufficient; keep feed fast to avoid melted edges. CNC routing can produce profiles but needs dust extraction, as the static-charged chips scatter easily.

What is the maximum service temperature of XPS200?
XPS200 is rated for continuous use to about 75°C (167 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
How much does XPS200 cost?
XPS200 is a standard-cost polymer ($$), cheaper than about 71% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
