| TechnoDur: Braves extremely low Temperatures Our new TechnoDur PBT compound is a thermoplastic which combines great hardness, stiffness and strength. TechnoDur is easily processed due to its perfect flow behaviour. The favourable sliding and wear characteristics as well as extremely high tenacity in temperatures below freezing are further advantages. Typical Applications TechnoDur compounds may be applied in the following areas: Electrical engineering: Lamp holders, micro switches, spools, brush-holder bridges, switches, cam divices, telephone housings… Automobile construction: Junction boxes, petrol filters, fuel tank caps, heating, folds, headlights, car body panels, spark plug connectors… Household appliances: Hair care appliances, components for toasters, fondue makers, coffeemakers… Other: pump components, gears guide applications: slide bearings and components…&& |
