Foam comprising (a) 5-85% ethylene homo- and/or co-polymer made by a high-pressure process and (b) 5-85% ethylene homopolymer and/or flexible ethylene copolymer made by a high-pressure process and showing a DSC melting point which is at least 5[deg]C below that of (a), also contains (c) 5-95% metallocene-polyethylene. An independent claim is also included for a method of foam production by feeding the above components into an extruder, melting and homogenising the mixture, injecting foam-forming gas, homogenising the mixture, cooling the mass, generating foam by extruding the mass into the open air through a temperature-controlled nozzle with a predefined cross-section and then cooling, drawing and guiding the foam. |
