Polyisocyanurate systems for Pour and Block Foam
Polyisocyanurate foams, referred to as PIR, is essentially modified polyurethane (PU) foam. Two advantages of PIR foam are improved fire-resistance and excellent insulation properties.
The proportion of MDI is higher than for PUR. As a result the MDI will also react with itself, producing strong chains of isocyanurate. These chains are stronger than normal bonds in polyurethane and results in a chemically and thermally more stable foam.
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
PIR Pour foam
Machine dispensed & "hand-mix" systems
Fire Retarded PIR & special use formulations
Density  45 kg / m³
PIR Rigid foam
Applications

AUSTHANE PIR 45 is suitable for  insulating applications in hot or cold environments, with ‘contact side’ temperatures ranging from  - 50 °C  to  + 130 °C.

AUSTHANE PIR 45
foam has better Fire Resistance properties than standard flame-retarded polyurethane foams.

AUSTHANE PIR 45
foam achieved a GROUP 1 Classification in accordance with Specification A2.4 of the Building Code of Australia when tested under the AS/NZS 3837 Standard. [CSIRO Test Report FNK 10180-July 2011 - a pdf document is available.].

AUSTHANE PIR 45
is formulated using
ecomate®  an “environmentally friendly” blowing agent with Zero ODP and Zero GWP.
The use of
ecomate® Blowing Agent results in the foam having excellent Thermal Insulation properties. The Thermal Conductivity k factor is 0.0215 W/m.K at 23.1 °C. [AWTA Test Report 187912 - 5 July 2011].
