RMP Cavity Fill USR

Polymer Group’s RMP Cavity Fill USR is an economical (low density) cavity filling foam based on polyurea silicate chemistry. Its rapid foaming and flame resistance characteristics make this an ideal product to fill voids in coal seams and fractured strata. The maximum exotherm reached during foaming is only 90°C, well under the accepted level for use in coal mines. RMP Cavity Fill USR can be used in wet environments where it shows good adhesion to wet surfaces and will not absorb water.
