Component A
Base, summer and winter — the polyol behind a 40%+ isocyanate foam.
40%+ isocyanateSee specificationProducts
Four grades, one filling technology
The grade is decided by one number: how much isocyanate the formula carries. Everything else — density, compression, closed cells, shrinkage, yield per can — follows from it.
The range
One chemistry, four isocyanate levels
The same polyol platform at four isocyanate shares. Higher share means denser cells, better adhesion and less shrinkage - and a can that costs more to fill.
Component C
General purpose, wide process window — the volume grade for engineering work.
24–27% isocyanateSee specificationComponent S
Economy entry grade — same technology package, lower isocyanate share.
18–21% isocyanateSee specificationColdOFF® Premium
Tighter cells, controlled shrinkage — the grade a price list cannot describe.

Choose by can, season and price band — not by a brochure
One page, one comparison. If a job sits between two grades, send the can spec and we will tell you which one to run.
| Criterion | A | C | S | Premium |
|---|---|---|---|---|
| Isocyanate share (α) | ≥ 40% | 24–27% | 18–21% | ≥ 40% |
| Adhesion class on aluminium | I | II | III (borderline) | I |
| Density, free rise (kg/m³) | 24–32 | 18–22 | 13–17 | 26–34 |
| Closed cell (%) | 85–92 | 75–85 | 60–75 | 88–93 |
| Yield per 750 ml can | 18–22 m | 24–28 m | 30–35 m | 17–21 m |
| Best season | base / summer / winter | all season | warm markets | base / summer / winter |
| Typical customer | window and facade makers, export brands | engineering fillers with many can types | volume retail brands, packaging | specification projects and tenders |
Typical values for orientation only. Final parameters are confirmed for the selected grade and your filling conditions.
How to choose
Three questions, then a sample
- 01
Send the can spec
Can volume, valve type, target fill weight. Three lines in a message is enough.
- 02
Tell us the season and the storage
Ambient temperature at filling, and where the cans will sit before they ship.
- 03
We send one or two candidates
Two 50 kg drums, the parameter card for your line, and a named engineer on WhatsApp.
Send your can spec — we reply with the grade, not a price list.
