    Abstract: The present invention relates to a polyoxymethylene molding composition comprising (A) 0.1-5.0% by weight of colorant, (B) 0.01-0.5% by weight of a nitrogen-containing stabilizer, (C) 0.05-1% by weight of an ester of a polyhydric alcohol and at least one fatty acid, and (D) 0.001-0.5% by weight of a metal salt of a fatty acid, and (I) polyoxymethylene polymer and, where appropriate, up to 40% by weight of other conventional additives, and variants of this constitution in advantageous versions. In the case of these polyoxymethylene molding compositions the selection of the colorants is no longer restricted to conventional colorants suitable particularly for POM. The products produced therewith are particularly stable during processing and feature low formaldehyde emission, defect-free surfaces, and high color fastness.

  • Patent number: 7419513
    Abstract: Compounds which have a benzotriazole and a hindered amine moiety in the same molecule are typified by the formula A wherein at least one of G2, R1 or R2 contains a hindered amine moiety are extremely effective light stabilizers having both the UV absorbing activity of a benzotriazole and the light stabilizing efficacy of a hindered amine in the same molecule. These compounds are effective stabilizers for thermoset resin compositions, thermoplastic resin compositions, for photographic applications, for pigmented or dyed polypropylene, polyamide or polyester fibers, and for white, dyed, dipped, unscented and/or scented candle wax against discoloration and fading when incorporated therein alone or in combination with an antioxidant.

  • Patent number: 7323502
    Abstract: Organic polymeric substrates, for example polyolefins such as polypropylene, can be made flame retardant by the incorporation of a synergistic mixture of (i) at least one compound selected from the group consisting of the (a) sterically hindered nitroxyl stabilizers, (b) sterically hindered hydroxylamine stabilizers and (c) sterically hindered alkoxyamine stabilizers and (ii) at least one phosphazene flame retardant. Advantageously, a further flame retardant may be added, without the need of adding an antimony synergist. The compositions of the invention combine good flame retardant properties with light stability and good mechanical properties.

  • Patent number: 7265171
    Abstract: The novel transparent polyolefin, polyester or polyamide article disclosed is stabilized against the effects of light, oxygen, heat and agressive chemicals by addition of 0.005-0.30% by weight the polymeric substrate of a hydroxyphenyl triazine UV absorber, and is characterized by its thickness between 1 and 500 ?m. Preferred polyolefin articles thus stabilized are agricultural films containing as further stabilizer a sterically hindered amine. The novel compositions act as selective UV filter especially useful in agriculture.

  • Patent number: 7259198
    Abstract: The present invention provides polyolefin compositions that are UV stable and suitable for articles that may be exposed to sunlight. The present invention provides, in one aspect, a polyolefin homopolymer or copolymer comprising, by weight of the polyolefin: (a) from 0.001 to 2 wt % hindered amine; (b) from 0.001 to 1 wt % ethoxylated amine; and (c) from 0.001 to 1 wt phenolic antioxidant; wherein the amount of phenolic antioxidant (PA), ethoxylated amine (EA) and hindered amine (HA) present in the composition is satisfied by the equation: PA + EA HA = Q wherein Q ranges from 0.15 to 250 when each component is expressed as a weight percentage. The composition is stable towards UV radiation such that it is useful for any number of articles such as automotive components and other articles that are, for example, injection molded.
