S-FOAM 128 is a variable ratio, self-skinning, 128kg density flexible foam. Skin thickness is controlled by material and mould temperature, and the loading of the mouLd. BJB Pigments may be added to the “B” side for developing a wide range of colours. S-FOAM 128 can be mixed by hand with a spatula, high shear mixer or machine dispensed. The 50/100 ratio yields the standard firm density of 128kg/mÂ³, while mixing at 30/100 ratio will result in a softer feel but the density will increase 208kg/mÂ³. This system is perfect for bumpers and crash pads, arms rests and seat cushions, movie props and special effects devices.
