Polyisocyanurate
systems for Pour and Block Foam
Polyisocyanurate
foams, also referred to as PIR, is essentially modified polyurethane (PU)
foam. Two advantages of polyisocyanurate foam are that it improved fire-resistancy
and has better insulation properties. (higher R-value).
The proportion
of methylene diphenyl diisocyanate (MDI) is higher than for PUR. As a result
the MDI will also react with itself, producing strong chains of isocyanurate.
These cross links are stronger than normal bonds in polyurethane. As a result
they are more difficult to break and are chemically and thermally more stable.
Advantages
of PIR
| • | Superior R-Value and thermal performance |
| • | Moisture resistance |
| • | Dimensionally stable |
| • | Excellent fire test performance |
| • | Unaffected by commonly used construction adhesives and solvents |
| • | Building
code conformance
