Abstract: A process for preparing a pigmented vinylidene fluoride polymer based powder coating composition that comprises dispersing at least one pigment In an aqueous dispersion or latex of a fluorine-free polymer that is compatible with the vinylidene fluoride polymer and, if needed, conventional paint additives, which may include a polyoxyalkylene glycol block polymer. Subsequently the aqueous pigment dispersion is blended with said vinylidene fluoride polymer powder, milled, dried, and classified to obtain the specified particle size.

Abstract: A process for preparing a pigmented vinylidene fluoride polymer based powder coating composition that comprises steps of dispersing at least one pigment in a solution of a fluorine-free polymer that is compatible with the vinylidene fluoride polymer, blending said vinylidene fluoride polymer powder with the pigment dispersion, removal of solvent, milling, and classifying the compound to obtain the desired product.

Abstract: Foamable and foamed polyvinlyidene fluoride materials prepared by compounding the PVDF with a suitable nucleating agent of discreet insoluble particles, a blowing agent having an activation temperature above the melting point of the PVDF, and a dispersing aid to provide a substantially homogeneous powdered mixture that is then melt compounded with high shear melt blending means and then extruded and quenched to provide the foamable polyvinylidene fluoride material which can then be extruded as an insulating material on wire at a temperature sufficiently high to activate the blowing agent.

Abstract: A diskette jacket is made from biaxially-oriented polyester film containing particles of a different polymer which provide a matte finish that aesthetically masks scratches and smudges. The polyester film provides better resistance to pillowing and to scratching as compared to the polyvinylchloride diskette jackets of the prior art.
