[Problem] To provide a composite preform that can ensure that worsening of the appearance of a surface of a plastic member caused by near-infrared heating prior to blow molding is effectively prevented and that an inner preform is efficiently heated.

[Solution] The composite preform of the present invention includes a preform and a heat-contractive plastic member, the preform including a mouth part; a trunk part linked to the mouth part; and a bottom part linked to the trunk part, and the heat-contractive plastic member being disposed so as to surround the outside of the preform and including at least a colored layer that contains a resin material and a colorant, wherein the heat-contractive plastic member has a near-infrared transmittance of 50% or higher.

A compact camera module that contains a generally planar base on which is mounted a lens barrel is provided. The base, barrel, or both are molded from a polymer composition that includes a thermotropic liquid crystalline polymer and a plurality of mineral fibers (also known as whisker). The mineral fibers have a median width of from about 1 to about 35 micrometers and constitute from about 5 wt. % to about 60 wt. % of the polymer composition.

The plastic structural article includes an elongated tubular shell having opposed end sections, a middle section there between and an interior cavity. The interior cavity has a foam core situated therein. The foam core comprises steam expandable polymer beads which when expanded substantially fill the interior cavity. The bead and shell are of a similar plastic composition enabling the articles to be reground and recycled. An apparatus for forming the articles and an associated method of manufacture are also disclosed. A thermal management system includes a panel having a periphery, and a skin having a thermal bond to an in-situ foam core. The panel has a thermal transmittance u-value ranging from 0.1 to 0.17 W/m.sup.2 C.

A flame-retardant flexible polymer composition includes a polymer component that contains 98 to 80 parts by mass of a chlorinated polyethylene and 2 to 20 parts by mass of a polyolefin polymer; and calcium hydroxide particles having a surface containing calcium silicate, wherein a content of the particles relative to 100 parts by mass of the polymer component is 5 parts by mass or more and 20 parts by mass or less. A polymer tube is formed from the flame-retardant flexible polymer composition. An insulated wire includes an insulation formed from the flame-retardant flexible polymer composition.

A novel tubular or profile shapes of co-extruded multilayer polymers. These materials contain tens to thousands of layers of milli-, micro- to nano- polymer layers. These new shapes contain contiguous layers of milli- to nano- polymer layers in three dimensions and these contiguous layers may be twisted or turned to further expand the potential microlayer geometries.

Polymer compositions, for example, recycled polymer compositions, processes for the production thereof, functional fillers for use in the polymer compositions, and articles formed from the polymer compositions.
