Fire-retardant composition of an alloy of polyamide and polyester resins
The present invention relates to a composition comprising at least a thermoplastic polyamide resin, a thermoplastic polyester resin, a reinforcing or bulking filler and a fire retardant. Said composition does not comprise any compatibilizer for the polyamide and the polyester, such as an agent of polymeric type, and especially no epoxy resin. Such a fire-retardant polyamide/polyester composition shows good compatibility and good mechanical and fire-retardant properties, especially a good capacity not to form flames in the presence of glowing agents, for example in the field of domestic electrical appliances, electrics and electronics.
Epoxy resin formulations
Formulations comprising from 10 to 80% by weight of the formulation of a halogenated epoxy resin; from 1 to 15% by weight of the formulation of an antimony based fire retardant; from 1 to 10% by weight of the formulation of an inorganic or non-polymeric organic phosphorous containing fire retardant; and from 1 to 30% by weight of the formulation of a curative system are provided. The formulations are particularly suitable for producing aircraft interior composite components having good fire retarding properties, low smoke emission, low smoke toxicity and low heat release properties. The formulations also have excellent processing and mechanical properties. Further components may be included in the compositions to improve various properties, including the fire retarding, low smoke emission, low smoke toxicity and low heat release properties and to also further improve the processing and mechanical properties, including toughness. Compositions produced from the formulations have excellent processing and mechanical properties, and may also have good surface finishes.
COATING MATERIAL AND PREPARATION METHOD THEREOF, HEAT EXCHANGER AND METHOD FOR TREATING HEAT EXCHANGER
The present disclosure relates to the technical field of material and heat exchange and in particular, to a coating material applied to a heat exchanger, a method of preparing the coating material, a heat exchanger, and a method of treating the heat exchanger. The coating material of the present disclosure applied to a heat exchanger includes a hydrophobic material and a light-to-heat conversion material. Under irradiation of visible light, the light-to-heat conversion material can effectively increase the surface temperature of a coated object, which is beneficial to increasing the surface temperature of the coated object while exerting the hydrophobic performance of the hydrophobic material, thus further improving the effect in slowing down frosting.
ANTIVIRAL ARTICLES
Provided is a textile made of filament yarn comprising a polymer composition that is durable and reusable having permanent or near-permanent antiviral properties and that includes a polymer, a metal ion, preferably a zinc and/or copper ion, and an optional phosphorus compound, wherein fibers and/or fabric formed from the polymer composition demonstrate antiviral properties and wherein the polymer is hygroscopic. The present disclosure also describes methods of forming the polymer compositions and methods of preparing fibers from the polymer composition.
