<p>Remoldable panels are produced by continuously plastifying and extruding an at least partially aggregated particulate mixture comprising about 40 to about 60 % by weight of thermoplastic resin, preferably polypropylene, and about 60 to about 40 % by weight of a particulate organic and preferably cellulosic filler such as wood particles, and rolling the web of extruded material prior to its solidification. The extruded and rolled web is cut to panels which can be used, for example, in the production of shaped articles such as dash boards or other components of automotive vehicles, furniture or parts thereof and the like, by pressing at elevated temperature or by other remolding methods conventionally used in the art of processing thermoplastic materials. Alternatively, the panels can be used for purposes where wood panels or ply-wood are normally employed.</p> |
