发明名称 Foam panel having a reduced thermal conductivity
摘要 Styrene polymer foam sheets with a density of 20 - 200 g / l and cross-section of &ge; 50 cm<2>, contain 0.5 - 40 wt.% glass microbeads, carbon black, iron oxide powder, bitumen or aluminium powder. The preparation of the sheets is also claimed, and involves extruding a mixture of a styrene polymer, 3 - 15 wt.% volatile propellent and 1 - 40 wt.% glass microbeads or aluminium powder at a temperature above the polymer m.pt. , and then foaming.
