Material Notes:

A regular molding grade consisting of spherical polystyrene beads containing pentane as expansion agent, typically used for high density foam applications.Applications: This grade is sued mainly for producing high density block and contour molding. It offer controllable pre-expansion, short maturing times, fast cycle time during molding and low shrinkage in the density range of 30-80 kg/m³.Information provided by NOVA Chemicals.
