摘要： The present invention relates to foamed products and method for producing them, comprising a plurality of coalesced extruded layers or layers of coalesced strands of a foamed thermoplastic composition having a low density, by
(a) providing at least one foamable composition comprising at least one polymer or copolymer and a blowing agent formulation,
(b) extruding the composition through a die having a plurality of orifices,
(c) foaming the extruded composition at a foaming temperature which is above the glass-transition temperature or the melting temperature of the polymer composition,
(d) maintaining the foaming product at an elevated temperature for a sufficient period of time to obtain adhesion between individual foam layers, and
(e) allowing the foamed product to cool,
characterized in that a foamed product is obtained comprising a plurality of adherent foam layers, wherein at least one of these foam layers extends across the whole breadth of the foamed product.摘要翻译： 本发明涉及发泡产品及其生产方法，该方法包括：通过
