Abstract: The present invention provides a thermoplastic olefin composition that is particularly suitable for use in extruding tapes or films that can be further processed to form the hook portion of hook-and-loop fasteners for use on disposable absorbent products. The thermoplastic olefin compositions according to the invention provide the opacity, tear strength and flexural modulus considered optimal for such applications. Thermoplastic olefin compositions according to the invention include an olefin component including a highly crystalline homopolymer of polypropylene, an inorganic particulate filler component, and a colorant package including titanium dioxide and iron oxide pigments.

Abstract: The present invention provides a new and improved flame retarded polyolefin composition that displays good retained physical properties upon aging. The composition also exhibits excellent moldability and it may be easily colored. In a preferred embodiment the composition includes a polyolefin, a halogen-containing flame retardant additive, from at least about 1.00% by weight to about 2.5% by weight of a stabilizer package, and from about 0% to about 1.0% by weight of an acid/halogen scavenger. The stabilizer package includes by weight from about 20% to about 80% of a hindered phenolic antioxidant, from about 20% to about 80% of a phosphite containing antioxidant, and from about 0% to about 40% of a thio-ester antioxidant. In addition to displaying excellent color and physical property development and retention characteristics, the composition of the present invention displays an improved UL94 vertical burn rating.
