The use of polytetrafluoroethylene micropowders having a particle size of generally less than about 20 microns as an additive for polyvinyl chloride or polyolefin unexpectedly produces compositions which are melt processable. Other unexpected properties include that the micropowder is deformable under shear and acts as a flame retardant.

The present invention relates to an improved modified polyamide having increased molecular weight and substantially the same or marginally increased viscosity versus shear weight as the unmodified polyamide. A method for modifying polyamides to provide these improved properties also is disclosed wherein a polyamide having an initial molecular weight is contacted with at least one organic peroxide, at least one coagent and / or one free-radical trap to form an improved polyamide having an increased molecular weight and substantially the same viscosity versus shear rate. The present disclosure also relates to polyamide compositions comprising organic peroxides and articles made from the modified polyamide.

A woven webbing for use in a tiedown or sling for lifting, restraint or other material handling functions. The woven webbing includes a central portion and tubular edges. The central portion has a top surface and an oppositely facing bottom surface. The top surface and bottom surface may be woven in a first pattern for strength and abrasion resistance while remaining flexible. The tubular edges extend from either side of the central portion. The tubular edges may be woven in a second pattern to improve the cut resistance of the tubular edges. The tubular edges have interior cavities which may include twisted floating yarn extending therethrough to enhance the cut resistance of the tubular edges. The tubular edges may include a high modulus yarn material which changes the orientation of the yarn material away from the axial direction of tension when a load is applied to the webbing.
