Abstract:
The invention relates to flame-protected polymer foams comprising at least one halogenated polymer, for example bromated polystyrol or styrol-butadiene-block copolymer, as a flame protection agent, having a bromine content in the range of 40 to 80 wt%, or tetrabromobisphenol-A compounds (TBBPA), to a method for the production thereof, and to flame-protected expandable styrol polymers.
Abstract:
The invention relates to a method for producing porous metal sintered molded bodies, wherein expandable polymer particles, in which a sinterable metal powder is dispersed, are expanded to form a molded body. The molded body is subjected to a heat treatment, wherein the polymer is expelled and the sinterable metal powder is sintered to form a porous metal sintered molded body. Preferably, styrol polymers are used. The sinterable metal powder is selected, for example, from aluminum, iron, copper, nickel, and titanium.
Abstract:
The invention relates to a molded composite article, especially for furniture making, containing a core layer and one or more additional layers, the core layer being a molded particle foam article which is obtained by welding pre-foamed foam particles from expandable, thermoplastic polymer granules containing 5 to 100% by weight of a SAN component (A) containing a1) 5 to 100% by weight (based on A) of a styrene/acrylonitrile copolymer, a2) 0 to 95 % by weight (based on A) of an α-methylstyrene/acrylonitrile copolymer and/or α-methylstyrene/styrene/acrylonitrile terpolymer, and 0 to 95% by weight of polystyrene (B) and 0 to 95% by weight of a thermoplastic polymer (C) which is different from (A) and (B).
Abstract:
A composite polystyrene foam molding with low thermal conductivity comprising 15 - 50% by volume of organic nanoporous particles, and 85 -50% by volume of prefoamed styrene polymer particles as well as a process for manufacturing such composite polystyrene foam moldings by steam-chest molding.
