Polyurethane - Polyurethane Foam
Rigid polyurethane foam has closed cell structure and has got better insulation properties then many other insulation materials. So it is widely used in building cold rooms and for insulation of piping and tanks in industrial / mining applications. Heat generated from curing fibreglass does not affect polyurethane foam thus enabling fibreglass lamination.
Polyurethane foam is widely used for marine buoyancy. One cubic metre of 35kg/M3 polyurethane foam would have a positive buoyancy of 965kg. Rigid polyurethane foam is used extensively by sculptors and artisans to create shapes as it can be easily carved, sanded in to difficult shapes quickly.
AFPT makes blocks of 1200mm x 2400mm and depending on the density usually blocks are made up to 600mm high. We stock 10mm to 600mm sheets in 35kg/M3, 60kg/M3 and 90kg/M3. Contact AFPT for any other densities required.
AFPT has a computerized bi-axle cutting machine to cut not only sheets of different thicknesses but also to profile cut different shapes. This amazing state of the art machine can cut letters for signage, wings for model aircraft, c-sections for piping insulation to name a few.
Foam filling in buoyancy appliances require special skills to avoid any air pockets that may occur. AFPT has many years of experience in both on-site and in house foam filling. AFPT has skills to fill small floats to large pontoons.
Liquid foam is supplied in both pour-in and spray on kits. Liquid foam kits are available in 2kg, 8kg and 40kg kits. Approximately a 2kg of kit can fill a cavity of 57Litres of volume.
