Foamable basic mixture and polyolefin - - resin composition with an excellent expansion capacity and excellent properties for direct metal-coating

摘要

The present disclosure provides a basic mixture, which, by melting and extruding a mixture which contains a polyolefin - resin has been prepared, wherein the mixture of 10 to 89 w -% of a polyolefin - resin, 5 to 30 w -% of a chemical as still, 5 to 30 w -% by means of heat expandable microcapsules and 1 to 30 w -% of an inorganic filler material contains. In addition, the present disclosure of a polyolefin - - resin composition with an excellent expansion capacity and excellent properties for direct metal-coating, which the foamable mixture contains. A cast article by foam injection molding of the polyolefin - resin - a composition according to a shape of the present disclosure has been obtained, can be useful, since it is a sufficiently good uniform distribution and sufficiently good mechanical properties of the foamed cells, so that the cast article well as a constituent of materials for the interior space / the outer of vehicles can be used and also the fuel efficiency of the vehicles is improved, since it enables the generation of lighter components.
