FOAM COMPOUND COMPOSITION Russian patent published in 2010 - IPC C09K3/10 C08L63/02 

FIELD: chemistry.

SUBSTANCE: invention relates to foam compound compositions used for cast moulding articles for radio- and electrical purposes, containing the following in pts. wt: 75-85 epoxy-diane resin ED-20, triglycidyl esters of polyoxypropylene triol 43.5-49.3 Laproxide-703 and 10.5-11.9 Laproxide-301, 30-34 ethylenediaminomethylphenol AF-2, 30-34 low-molecular polyamide resin PO-300, 15-17 polyhydrosiloxane liquid 136-41, 1.5-1.7 foam regulator Penta-483, 1.5-1.7 brand A catalyst, 3.7-4.3 ethylsilicate-40 and 0.02-0.03 acetone.

EFFECT: low level of matching in the frequency band (VSWR - 1,25-1,35), increase in amplification coefficient of the emitter in a wide frequency range by 0,5 dB, levelling of the beam shape of the emitter with retention of its high mechanical strength under impact and vibration loads.
