Abstract (en)

[origin: WO0153399A1] An extruded polyolefin foam in thicknesses of at least about 12 mm and greater of improved compressive strength, extensional viscosity, and reduced aging time and a process for making the foam are disclosed. The foam is prepared using a propane blowing agent. The beneficial properties imparted to thicker grade and plank foams by a propane blowing agent can be achieved with up to as much as 75 % by volume of either normal butane or isobutane or both in the blowing agent, depending on the polyolefin selected.
