PØLYPHEN® FOAM TECHNICAL DATA

General

PØLYPHEN® is a rigid thermal insulation foam, which combines good mechanical properties with high fire resistance.
It can be used in a wide range of applications, including sandwich panels and lagging of pipes, ducts and tanks.
The product is light weight, easy to cut and has a surface that is not fibrous, friable or brittle.
PØLYPHEN® can be produced in a wide range of densities from 30 kg/m3 to 300 kg/m3 (2-20 lbs/cu ft), depending on the intended application. The density range of greatest commercial interest is 30-60 kg/m3 (2-4 lbs/cu ft) which covers most applications for thermal insulation foams.
PØLYPHEN® is available in block form, or sheets (up to 600 mm thick) or a variety of profiles e.g. pipe lagging or curved segments for tank insulation. In fact, almost any shape can be produced using standard cutting equipment, such as computerised abrasive wire cutters.
