2 Component liquid self blowing silicone foams

Silicone Solutions Ltd offer a range liquid foams which when mixed are pourable or injectable into cavities, open and closed moulds. The materials react at room and elevated temperature and, in some cases, can be adjusted for reaction time and final density. Although they can be hand mixed they are more consistent when mixed via cartridge/static mixers and by automated mix/dispense equipment

Being silicone they offer better elevated temperature performance (up to 250C) than a polyurethane and tend to be better in control of smoke and flame when subject to fire.

Typical applications are for;

• Low density seals in aerospace for weight saving.
• Flame retardant mouldings for defence applications.
• Low stress potting enabling thermal expansion without undue force on enclosures.
• Heat insulation.
• Kinetic impact resistance.
• Formed in place gaskets in under bonnet automotive applications.
• Sealing electrical enclosures.
