Thermal insulating composite structure

摘要: IMPROVED INTEGRAL, THREE-LAYERED PLASTIC, THERMALLY INSULATING COMPOSITES EACH HAVING AN IMPACT RESISTANT SOLID FACING LAYER OF A MONOVINYL AROMATIC COMPOUND/ALPHAELECTRONEGATIVELY SUBSTITUTED ETHENE COMPOUND INTERPOLYMER SYSTEM, CELLULAR POLYURETHANE, AND ELASTOMERIC INTERLAYER POSITIONED BETWEEN THESE TWO LAYERS. THE RESULTING HAVE RESISTANCE AS RESPECTS LAYER.
