​INSUL PUR

 

​Polyurethane which was invented around the late 1930's is used by many people nowadays. Whether we realise it or not, we sleep, sit and walk on it, pass under, drive in and fly with it. We even change the colours of our lives with it as we refurbish our world with it. To help protecting our world and her vunerable environment, we insulate with it. Polyurethane block foam (PUR) is made by mixing a polyol blend with an isocyanate and a blowing agent. The components used and the production method determine the end properties of the foam. Specific characteristics for these foams are density, dimensional stability, foam stru​cture, compressive strength, fire behavior and insulation value. All PUR block foams have high insulation values and are available in densities of 32 kg/m3 up to 200 kg/m3..

This is then fabricated into pipe sections or Panels and supplied for the insulation of all types of building service/process pipe and ductwork.
