Antimicrobial flame and smoke retardant molding compounds and components molded from these compounds
Publication number: 20110195211Abstract: HVAC and building and construction components are molded from novel compositions that meet the flame spread and smoke index, and the molding, safety, strength, and aesthetic requirements for this use. In a further embodiment, these compounds also promote better indoor air quality by inhibiting the growth of microbial contaminants within and on the surface of products molded therefrom. These compounds are based on thermoset resin, e.g. a polyester resin which preferably can comprise a polypropylene glycol dicyclopentadiene copolymerized with maleic anhydride, a low profile additive and hydroxy ethyl methacrylate monomer with additional additives including an appropriate catalyst package, a mold release agent, a thickening agent, a loading of aluminum hydroxide which is from about 40 to 65% by weight, having a loading of glass fibers of from about 10 to about 25% and preferably containing a silver ion containing antimicrobial agent, such as soluble glass containing silver ions.Type: ApplicationFiled: April 8, 2011Publication date: August 11, 2011Applicant: Premix Inc.Inventors: Thomas J. Cebasek, Michael Gruskiewicz, Steven T. Searl -
Publication number: 20110190436Abstract: There is provided an acrylic adhesive composition which comprises: (A) a vinyl polymer comprising a homopolymer or a copolymer of an alkyl (meth)acrylate having a C4 to C14 alkyl group; (B) an organophilic layered double hydroxide organically treated with an organic anion; and (C) a crosslinking agent. Therefore the obtained adhesive composition has sufficient adhesiveness to an object, excellent heat resistance and excellent adhesive properties particularly at higher temperatures, and is substantially free from variations in adhesiveness.Type: ApplicationFiled: October 15, 2008Publication date: August 4, 2011Applicant: NATIONAL INSTITUTE FOR MATERIALS SCIENCEInventors: Takashi Oda, Kenji Tamura

Publication number: 20110168425Abstract: Commercial thermoplastic clean flame retardant materials in wire and cable insulation are mechanically unstable due to high filler loading. In the present invention, thermoplastic, black color, clean flame retardant composition using carbon nano tubes (CNT) is made. The resultant compositions possess very low smoke and toxicity. CNT with outer diameter of 40-60 nm and length of under 20 ?m are used to increase mechanical properties and flame retardancy. Thermo plastically extruded composition consists of each component by parts by weight as follows: 100 of resin (polyolefin or 100 of polyolefin/ethylene propylene diene monomer (EPDM)), 90-150 of non halogen containing flame retardants, 1-20 of auxiliary secondary flame retardant agents, 2-4 of CNT (outer diameter of 40-60 nm) and length under 20 ?m and 0.2-1.0 of antioxidants. A reliable method for producing thermoplastic black color clean flame retardant insulation material for wire and cable without deterioration of mechanical properties is discussed.Type: ApplicationFiled: January 8, 2010Publication date: July 14, 2011Inventors: Ahmed Ali Basfar, Hun Jai Bae
