Processing & How to Use

1

Condition
Bring SPC-10081 and MDI to a material temperature of 20–25 °C; keep the mould at 35–40 °C.

2

Mix
Combine SPC-10081 : MDI at 100 : 136–145 pbw with 12–14 pbw cyclopentane, using low- or high-pressure foaming equipment.

3

Pour & Foam
Cream 8–16 s, gel 45–90 s, tack-free 80–120 s for even, well-distributed foam density.

4

Cure & Demould
Allow to cure in the mould; demould after about 6–8 min depending on foam thickness.

Packaging, Storage & Handling

Packaging
Polyol supplied in 200 kg net iron drums; MDI typically in 250 kg drums. Palletised for export; bulk volumes on request.
Storage
Store sealed at 10–25 °C in a dry, well-ventilated area, away from moisture. Shelf life 6 months under recommended conditions.
Handling & Safety
Avoid contact with eyes and skin; wear safety glasses. Wash affected skin with soap and water; flush eyes with plenty of water and seek medical attention. Full MSDS available on request.

Frequently Asked Questions

What blowing agent does SPC-10081 use?
A cyclopentane (C-pentane) blown system — an environmentally friendly, zero-ODP blowing agent at a recommended 12–14 pbw.
What foam density and closed-cell rate does it achieve?
Moulding density ≥ 35 kg/m³ with a closed-cell rate ≥ 92%, giving low thermal conductivity (≤ 21 mW/(m·K)) for efficient refrigerator and freezer insulation.
Is it suitable for both manual and high-pressure machine foaming?
Yes — recommended reactivity is provided for both manual (low-pressure) and high-pressure machine mixing; see the reactivity table above.
What is the minimum order quantity?
MOQ is flexible for trial runs and line validation, with tiered lead times for bulk volumes.
Can the formulation be customized?
Yes. Reactivity and density can be tuned to your line and cabinet design. OEM/ODM is supported — request a TDS, MSDS and a free sample, and we reply within 24 hours.
