Nanocomposites Broaden Roles in Automotive, Barrier Packaging
Nanocomposites are gradually gaining acceptance in the mainstream of global plastics processing. These polymer compounds, containing relatively low loadings (under 6% by weight) of nanometer-sized mineral particles, are beginning to show up in polypropylene and TPO-based automotive exterior claddings, barrier beer bottles, nylon packaging films, polyethylene pipe and wire/cable coatings, and more.

Probably the most intriguing news in extrusion at K 2001 will be a novel way to extrude clear film that differs from standard blown and cast methods.
Read MoreFoaming Expands Possibilities for Wood-Fiber Composites
Over a dozen processors already foam wood-fiber composites and an equal number are experimenting with it. Foaming with wood cuts resin cost and weight in half and brings design advantages. But it also requires particular know-how in materials formulation and extrusion hardware.
Read MoreDie Drawing Makes ‘Plastic Steel’From Wood-Filled PP
A developer of new plastics technologies is applying low-temperature die drawing to take advantage of a new raw material: expanded, oriented, wood-filled polypropylene (EOW-PP).
