BISCO® SOLID SILICONES

BISCO®bun silicone is a cellular silicone that is cast into blocks up to 8 inches thick. This lightweight, high quality material is typically used in cushioning and sealing applications and features FST (flame, smoke, toxicity) resistance. With a low compression set, and superior weather and UV resistance, this foam is favored as a cushion foam in passenger rail car and mass transit seating.

MF1®Bun Silicone comes in soft, medium, and firm in it’s traditional white color. MF1-55 is now available in gray, and is targeted more toward general industrial applications. BISCO®SilFXTM foam is the lightest silicone foam that is specially designed for aircraft seating and cushioning. As a non-petroleum, open-cell silicone, SilFXTM eliminates the need for fire-blocking while allowing for thinner seat cushions with lasting comfort.
