Refined foam production for use as filling for cushions, particularly in mining industry or as filter material for air or fluid filters, involves selecting foam with soot formation, below given threshold value
Refined foam production for use as filling for cushions, particularly in mining industry or as filter material for air or fluid filters, involves selecting foam with soot formation, below given threshold value
Refined foam production involves selecting a foam with a soot formation, below a given threshold value from the quantity of the heavily or normally combustible foam. The density of the selected foam is reduced in relation to its normal density by mechanical treatment.
