SDS and COA
One safety data sheet per grade, one certificate of analysis per batch, batch number printed on the drum.
Grade S
Component S — economy grade, same technology package
For brands that win on volume in price-sensitive markets and still need a documented, repeatable can.
In the drum
What arrives, and what it is
Component S is formulated for an 18–21% isocyanate share. That produces a lighter, higher-yield foam: 30–35 m per 750 ml can against 18–22 m for Component A. It is the right material for temporary sealing, AC holes, packaging and non-load-bearing joints — and the wrong material for a window frame you expect to stay sealed for ten years. We say so on this page, on the datasheet and in the SOP.
Packed in 200 L steel drums, five drums to the tonne. Every drum carries the batch number that matches the COA in your inbox.

Typical values for orientation only. Final parameters are confirmed for the selected grade and your filling conditions.
Finished foam
What your line can reach with this grade
Typical values for the foam this component is formulated for, at the isocyanate share shown. Your numbers follow your can, your gas and your line — the sample is how we narrow them.
| Finished-foam parameter | Typical value |
|---|---|
| Isocyanate share of net weight (α) | 18–21% |
| Isocyanate : polyol ratio (β) | 0.25–0.30 : 1 |
| Apparent density, free rise (kg/m³) | 13–17 |
| Compressive strength at 10% (kPa) | 12–20 |
| Tensile adhesion on aluminium (kPa) | 40–55 · borderline III |
| Dimensional stability, 48 h (%) | 4–8 |
| Closed-cell content (%) | 60–75 |
| Yield per 750 ml can, 20 × 20 mm joint | 30–35 m |
| Shelf life, unopened can | 6–9 months |
Typical values for orientation only. Final parameters are confirmed for the selected grade and your filling conditions.
Fit and limits
A grade is defined as much by what it refuses to do
Where it fits
- Can types: 750 ml economy cans, often with a straw actuator.
- Best for high-volume retail brands and packaging applications.
- Same drums, same documents, same technical package as A and C.
Where it does not
- Not for window and door frame fixing — shrinkage shows up as leaks in year two.
- Not for external or wet exposure; closed-cell content is 60–75%.
- Not for joints with movement; it is a filler, not a seal.
On the line
Four things that decide the first run
- Fill the first two drums strictly by the parameter card and log every weight. That log is what lets you loosen later.
- Hold the drum at 18–25 °C. Warm it slowly if the store is cold — never with an open flame, never in one spot.
- Flush the line when you change grades: 20–30 minutes, then recalibrate the fill weight.
- Keep one can per batch, cut it the next day and photograph the section. Two years of those photos end most quality arguments.
Documents
What travels with the drums
Form E and packing list
ASEAN origin documentation prepared before booking, so the customs broker is not chasing paper at the port.
Transport appraisal
Non-dangerous goods appraisal on request — the document a shipping line will ask for when the drum is a raw material.
Marks and traceability
Pallet marks in your format, retained samples kept two years, and a written answer if a batch ever needs investigating.
Questions
Three questions on this grade
Why does Component S foam so much more?
Higher blowing-agent share and lower isocyanate share. Yield per can goes up, density and closed-cell content go down. That is the trade, and it is why we print the limits on the datasheet.
Can I sell it as a window foam?
Please do not. Two winters later the frame leaks, and the conversation is about your brand, not about the grade. We will help you position it where it wins: temporary sealing, AC penetrations, packaging.
Is S the same technology package?
Yes — same SOP structure, same parameter cards, same troubleshooting table, same training videos. The grade changes; the support does not.
