Polyolefin powder, processes for making and using slush molded articles made from the same

   
   

Slush moldable polyolefin powders are prepared by blending a crosslinkable silane-grafted, olefinic interpolymer, optionally containing a crystalline polypropylene homopolymer or interpolymer; and a crosslinked silane-grafted, olefinic interpolymer containing a cure catalyst, the blend optionally containing a crystalline polyolefin powder. The resulting compositions can be slush molded to make a variety of articles of manufacture, especially automotive interior components, having good hot tear properties, low hardness and no glossing after heat aging.

Os pós moldable do polyolefin da lama são preparados misturando um interpolymer silane-silane-grafted, olefinic crosslinkable, opcionalmente contendo um homopolymer ou um interpolymer cristalino do polypropylene; e crosslinked silane-silane-grafted, interpolymer olefinic que contem um catalizador da cura, a mistura que contem opcionalmente um pó cristalino do polyolefin. As composições resultantes podem ser lama moldada para fazer uma variedade dos artigos da manufatura, especial componentes interior automotrizes, não tendo propriedades quentes boas do rasgo, a dureza baixa e nenhum anotar após o envelhecimento de calor.
