Water-Blown Rigid PU Foam for Sound-Insulation Panels

Water-blown rigid PU foam polyol for structural and sound-insulation panels — higher density with eco-friendly blowing.

Get a Free Quote

This is the water-blown, high-density grade of our two-component rigid polyurethane foam (SKU: SPC-10062-W), engineered for sound-insulation and high-load sandwich panels. The water-blown system reaches a higher core density (80–120 kg/m³) for superior compressive strength and noise dampening, while keeping a low thermal conductivity (λ ≤ 0.02 W/(m·K)) — ideal for cold-room, partition and structural panels. Prefer a lower-density, best-insulation grade? See our cyclopentane-blown SPC-10062.

Processing & How to Use

1

Condition
Bring both components to a stable working temperature before mixing.

2

Mix
Combine component A and B at a 1:1 ratio by weight with isocyanate (MDI), using low- or high-pressure equipment.

3

Pour / Inject
Dispense into the panel mould or continuous line; maintain a mould surface temperature of about 40 °C.

4

Cure & Demould
Cure in the mould per panel thickness, then demould for a uniform, well-bonded core.

Packaging, Storage & Handling

Packaging
Polyol in 200 kg net iron drums; MDI in 250 kg drums. Palletised for export; bulk on request.
Storage
Moisture-proof, ventilated, sealed storage. Shelf life 6 months under recommended conditions.
Handling & Safety
Avoid eye/skin contact; wear safety glasses. Wash skin with soap and water; flush eyes with water and seek medical attention. Full MSDS on request.

Frequently Asked Questions

What is the difference between the water-blown and cyclopentane grades?The water-blown SPC-10062-W reaches a higher density (80–120 kg/m³) for greater strength and sound insulation, while the cyclopentane SPC-10062-CP is lower density (30–43 kg/m³) for the best thermal insulation.
What is the A:B mixing ratio?A simple 1:1 ratio by weight, for easy, reliable metering on continuous panel lines.
What flame-retardant grade does it meet?The standard grade meets a B1 fire rating, adjustable to suit your target market’s regulations.
What is the minimum order quantity?Orders start from just 10 kg, ideal for trial runs and line validation, with tiered lead times for bulk volumes.
Can the formulation be customized?Yes. Density and reactivity can be tuned to your line and panel specification. OEM/ODM supported — request a TDS, MSDS and free sample; we reply within 24 hours.
