Abstract:
The invention relates to a flame-retardant thermoplastic material, comprising thermoplastic base resin, a flame retardant, and an optional antioxidant, wherein the flame retardant comprises a complex of phosphine oxide and a transition metal salt. The invention also relates to flame-retardant thermoplastic expanded beads. A foam molding prepared from the flame-retardant thermoplastic expanded beads has good flame-retardant and antistatic properties, has excellent mechanical properties and is widely used.
Abstract:
The invention relates to a holder (1) for a sensor (2) for detecting properties of a medium which flows though a line (3), said holder being arranged in a receiving part (7). Said receiving part (7) is housed in a housing (5) which is combined with the line (3). The receiving part (7) which is arranged at least partially in the flowing medium is sealed with respect to the line (3) of the housing (5). The aim of the invention is to provide a holder (1) for an extremely fast temperature sensor for media in the form of chemicals. This enables, for example, temperatures of the used media/chemicals to be adjusted quickly, since the temperatures can be detected quickly.
Abstract:
A conductive ink may include a nickel component, a polycarboxylic acid component, and a polyol component, the polycarboxylic acid component and the polyol component being reactable to form a polyester component. The polyester component may be formed in situ in the conductive ink from a polyol component and a polycarboxylic acid component. The conductive ink may include a carbon component. The conductive ink may include an additive component. The conductive ink may include nickel flakes, graphene flakes, glutaric acid, and ethylene glycol. The conductive ink may be printed (e.g., screen printed) on a substrate and cured to form a conductive film. A conductive film may include a nickel component and a polyester component.
