  • Patent number: 8921434
    Abstract: A polylactic acid composition is produced with an MI value of 0.05 or more and 5 or less, the MI value being measured at 190° C. under a load of 21.6 kg in accordance with JIS K7210 (ISO 1133). A polylactic acid is crosslinked with a polyisocyanate to generate a cross-linked polylactic acid, including a large cross-linked polylactic acid molecule which inhibits foaming. The cross-linked polylactic acid is mechanically grinded-by applying a shear force to decrease a molecular weight of the large cross-linked polylactic acid molecule. The amount of the polyisocyanate combined is 0.4 to 5% by weight based on the polylactic acid. The grinding is conducted in supercritical condition of an inert gas. A foam molded article is made from the polylactic acid composition.

  • Patent number: 8828551
    Abstract: The general field of the invention is that of airbags. The invention relates to a process for improving the tear strength and the combing strength of coated fabrics intended for uses in the field of inflatable bags, using a silicone composition comprising an additive consisting of a polyorganosiloxane resin (V) and a calcium carbonate. After coating the composition onto the fabric supports and curing, the coated supports not only have optimum adhesion and crease resistance properties, but also have good properties in terms of combing strength and tear strength.

  • Patent number: 8822580
    Abstract: Custom-tinted paints and stains are made using an array of low VOC concentrated liquid colorants including at least at least white colorant; black colorant; and green-hued, blue-hued and red-hued primary colorants at least one of which primary colorants comprises polyalkylene glycol humectant, ethoxylated surfactant and extender pigment. For colorants in the array containing polyalkylene glycol humectant, the humectant and ethoxylated surfactant amounts are sufficiently high and extender pigment amount is sufficiently low so that the colorants will not problematically plug colorant dispenser orifices if left in the dispenser without an orifice cap for a full day. The polyalkylene glycol humectant is also present in an amount sufficiently low so that dried paint films made by mixing the colorants with a clear waterborne base paint will resist blocking.
