Abstract:
The invention relates to flame retardant compositions comprising heptaphosphorus-derived compounds and to novel heptaphosphorus-derived compounds. These heptaphosphorus-derived compounds are especially useful for the manufacture of flame retardant compositions based on thermoplastic polymers, especially polyolefin homo- and copolymers, polycondensates, such as polyamides, or polyesters and duro-plastic polymers, such as the ones based on polyepoxides.
Abstract:
The invention relates to thermoplastic moulding masses containing: A) 10 to 99 percent by weight of at least one thermoplastic polyamide; B) 0.01 to 30 percent by weight of at least one highly branched or hyper-branched polyether amine; C) 0.5 to 80 percent by weight of a thermally conductive filler; D) 0 to 70 percent by weight of further adjuncts, wherein the sum of the weight percentages of components A) to D) is 100 %.
Abstract:
The invention relates to the use of thermoplastic molding compounds, comprising as substantial components: A) 29 to 99.95 wt % of a polyesters, B) 0.05 to 2.0 wt % of Na
Abstract:
The invention relates to a process for the production of a component, comprising an insert part (1) sheathed by a plastics layer, by, in a first step, sheathing of at least one part of the insert part (1) with a plastics molding composition (2) with low viscosity and, in a second step, using a hard plastics component (3) for overmolding of the insert part with the sheathing, or by sheathing of the insert part (1) with a hard plastics component (3), regions of the insert part (1) here not being sheathed, and overmolding of the non-sheathed regions with a plastics molding composition (2) with low viscosity. The invention further relates to a component comprising an insert part and comprising plastics sheathing which is composed of at least two plastics components, where the first plastics component, which at least to some extent directly sheathes the insert part (1), is a plastics molding composition (2) with low viscosity, and the second plastics component is a hard plastics component (3).
Abstract:
THE INVENTION RELATES TO THE USE OF THERMOPLASTIC MOULDED MASSES CONTAINING, AS ESSENTIAL CONSTITUENTS: A) BETWEEN 29 AND 99.8 WT. % OF A POLYESTER; B) BETWEEN 0.2 AND 2.0 WT. % OF ALKALI METAL SALTS OF ALIPHATIC CARBOXYLIC ACIDS OR THE MIXTURES THEREOF, IN RELATION TO 100 WT. % OF A) AND B); AND C) BETWEEN 0 AND 70 WT. % OF OTHER ADDITIVES, THE SUM OF THE WT. % OF A) TO C) AMOUNTING TO 100 %, FOR PRODUCING ALL TYPES OF LASER-TRANSPARENT MOULDED BODIES.
