A thermally conductive polyamide compound is disclosed. The compound comprises a polyamide matrix and zinc sulfide dispersed in the matrix. Optionally, reinforcing filler or a second polymer or both is present. Optionally, thermal carbon black or the combination of thermal carbon black and colorant is present. The compound can be extruded or molded into a heat dissipating article.

A heat stabilized polyolefin nanocomposite is disclosed, which contains metal scavengers to heat stabilize the nanocomposite.

Stabilized polyolefin nanocomposites

nuc-PP nanocomposite is made from the mixing of nuc-PP with olefin elastomer and organoclay, and optionally, a dispersion agent. Unexpectedly, processing properties such as higher melt flow, and performance properties such as higher toughness and higher stiffness, are obtained when compared with commercially available PP nanocomposite.

Nucleated polypropylene nanocomposites

HDPE nanocomposite is made by mixing HDPE with organoclay. Such HDPE nanocomposite contains concentrations of organoclay less than 4 weight percent. Unexpectedly, using less organoclay than that conventionally recommended, results in superior oxygen and water vapor transmission rates for HDPE compounds. The HDPE nanocomposite is useful for packaging films and containers for food or other perishables.
