Foamed silicone 

Foamed silicones are fluid bicomponent products that are used in the manufacture of compression joints (DFG = Dispensed Foam Gaskets). Once the two components are mixed and dispensed in a groove using a mixing robot, the product polymerise quickly at room temperature by a polyaddition mechanism. During crosslinking, the mixture releases dihydrogen gas, which allows the foaming of the silicone and the formation of a cellular foam (about 70% open cells).

Once cured, the silicone foam has a very low hardness, which makes it easily compressible and requiring only moderate tightening forces. The optimum compression ratio for achieving good sealing is between 45% and 55%.
