Beschreibung
Zusammenfassung:	FIELD: polymer materials. SUBSTANCE: invention, relating to polymer products suitable for protective coatings of constructional units, pipelines, and integrated insulation, provides heat-insulating composition with density 51-75 kg/cu.m based on rigid polyurethane foam and consisting of polyurethane, 70-95%, and glass microspheres, 5-30%, the latter being represented by fraction 30-50 mcm, 60-140 mcm, or mixture thereof. EFFECT: reduced inflammability of foam, increased its light resistance, compression and bend strength, and also improved workability in flooding and spraying operations. 4 cl, 1 dwg, 3 tbl
