Polyurethane Rigid Foam HR, A component B, 1.83 kg of packaging

Unicelschuim HR Two-component PUR hard foam with closed cells, and a density of 40 kg / m3. Suitable for thermal and acoustic insulation and for making floats. Foaming: 25 times. (1 Kg. Component A and B will depend on the friction from 20 to 25 liters of foam.) Foam, closed cells. Eviction 1: 25; gives hard outer skin specific gravity = 40 kg / m³ Mixing ratio: 1: 1.2 1.83 kg = 2.18 x 25 liters = 54.5 liters of foam at the right conditions (stirring / temperature)
