The present invention relates to the use of pelletized flame retardants and flame retardant compositions in the formation of flame retarded formulations, the resulting flame retarded formulations, and molded and/or extruded articles made from such flame retarded formulations.
Abstract:
The present invention relates to novel molding compositions based on semicrystalline engineering thermoplastics which, in conventional processing techniques, give moldings with reduced surface gloss. A feature of the molding compositions is that they comprise, in a polymer matrix, if appropriate with the usual additives, polymer particles with a median size d50 of from 0.1 μm to 100 μm, and comprise at least one other incompatible or semicompatible polymer which has not been chemically crosslinked, and also, if appropriate, comprise salt-like additives.The invention further relates to moldings which are produced by means of conventional processing techniques, in particular via injection molding, from these matt-effect molding compositions.
Abstract:
The present invention provides a thermoplastic resin composition containing (A) a resin mixture including (a-1) a polycarbonate resin in an amount of 45 to 97% by mass and (a-2) a fatty acid polyester in an amount of 55 to 3 % by mass, and (B) a rubber-like elastomer in an amount of 0.5 to 20 parts by mass per 100 parts by mass of the resin mixture, wherein component (B) is dispersed in an interface between ingredient (a-1) and ingredient (a-2) or in domains of ingredient (a-2). The composition has high impact characteristics and high fluidity and overcomes appearance defects such as pearl-like gloss and jetting marks.
Abstract:
Disclosed are a resin composition comprising a polylactic acid resin and a polyacetal resin, and such a resin composition in which the polylactic acid resin and the polyacetal resin are kept miscible with each other. The resin composition has good moldability, workability, mechanical properties, heat resistance and transparency, and may be worked into moldings, films and fibers for practical use.

Abstract:
The present invention provides an aromatic liquid crystalline polyester film excellent in the adhesion property to a substrate. Such film is obtained by an aromatic liquid crystalline polyester film obtained by casting an aromatic liquid crystalline polyester solution composition containing a solvent containing a halogen-substituted phenol defined by the following general formula (I): (wherein A is a halogen atom or a trihalomethyl group; i is an integer of 1 to 5; and in the case i is 2 or higher, the respective A may be the same or different), an aromatic liquid crystalline polyester, and a non-liquid crystalline resin at ratio of 1 to 200 parts by weight of the non-liquid crystalline resin to 100 parts by weight of the aromatic liquid crystalline polyester on a substrate; and removing the solvent.)
Abstract:
A flame retardant thermoplastic composition having excellent physical properties comprises about 20 to about 90 wt. % of a polycarbonate resin; up to about 35 wt. % of an impact modifier; about 0.5 to about 30 wt. % of a polysiloxane-polycarbonate copolymer comprising about 8 to about 30 wt. % polydimethylsiloxane units or the equivalent molar amount of other diorganosiloxane units; and about 0.5 to about 20 wt. % of a phosphorus-containing flame retardant, each based on the total combined weight of the thermoplastic composition, exclusive of any filler. In one embodiment a sample of the thermoplastic composition having a thickness of 2.5 mm (±10 % ) achieves a UL94 5VA rating Thinner samples may also achieve this rating. The compositions are useful in forming flame retardant thin-walled articles.

Abstract:
A sludge powder and sealant are prepared from paint sludge. A sludge powder is generated from a paint sludge having a volatiles content of 0-50% by weight by adding a processing filler thereto. A sealant composition is prepared by thereafter or concurrently therewith adding sealant ingredients including polymer, plasticizer, curative, and other sealant ingredients such as an adhesion promoter and sealant filler materials to the sludge powder. Alternatively, a sealant composition may be prepared by adding a paint sludge having a volatiles content of 0-50% by weight to the sealant ingredients, which may include a processing filler.
