    Abstract: A conductive polymeric composition includes, based on a total weight of the conductive polymeric composition, 0.1 wt % to 10 wt % of carbon nanotubes, 0.2 wt % to 4 wt % of a first component, 0.1 wt % to 4 wt % of a second component made by esterification of a C16-C30 fatty acid with a polyol compound, and the balance being a polymeric component. When the first component is a first polymer obtained from polycondensation of an aromatic diacid compound and an aliphatic glycol compound, the polymeric component is a polyester. When the first component is a second polymer obtained from polycondensation of a lactam compound, a diamine compound and a dicarboxylic acid compound, the polymeric component is a polyamide.

    IPC: C08L67/08

    Abstract: An impact-resistant polyester material is provided, which includes a polyester resin matrix material, a toughening agent and a compatibilizing agent. The toughening agent and the compatibilizing agent are dispersed in the polyester resin matrix material. The toughening agent is a polyolefin elastomer (POE). The compatibilizing agent is configured to assist in improving compatibility between the toughening agent and the polyester resin matrix material. The compatibilizing agent is at least one of a polyolefin elastomer grafted with glycidyl methacrylate (POE-g-GMA) and a polyolefin elastomer grafted with maleic anhydride (POE-g-MAH). The compatibilizing agent is configured to assist the toughening agent to be dispersed into the polyester resin matrix material with a particle size between 0.5 micrometers and 1.5 micrometers, so that the impact-resistant polyester material has an impact strength of not less than 20 kg-cm/cm.

    Abstract: Described herein is a Low TVOC flame-retardant polyurethane spray foam system, including at least one isocyanate as isocyanate component, and at least one substance reactive toward isocyanate, chain extender and/or crosslinking agent, flame retardant, blowing agent, catalysts, and additives and/or auxiliaries, as resin components, where the flame retardant includes expandable graphite and melamine, the amount of expandable graphite is in the range of from 5 wt % to less than 30 wt %, and the amount of melamine is in the range of from greater than 5 wt % to 30 wt %, each based on the total weight of the resin components. Also described herein are a polyurethane spray foam produced therefrom, the preparation thereof, and a method of use thereof in the application of heat insulation, sound insulation, cavity filling and damping packing.
