Window and/or door profiles of plastics material and process for producing these profiles by the extrusion method using plastics material of lower stability

摘要

A description is given of window and/or door profiles of plastics material which can be processed by the extrusion method and is based on polyvinyl chloride mixed with lubricants, fillers, pigments and, in particular, stabilisers, the profile inner regions (2) of which consist of a less stable plastics material which has been adapted in its mechanical properties to the stable plastics material, of a similar or identical composition, provided for the profile outer regions (1).
