    摘要: The present invention relates to a process for producing ROHACELL® foams with a compacted surface. Markedly less adhesive then has to be applied during lamination and the good mechanical properties of the ROHACELL® foams are retained. The invention further permits the use of ROHACELL® foams as a removable core.
