Housing of DuPontT Zytel HTN for map-controlled thermostat
The housing of the map-controlled thermostat by Behr Thermot-tronik, of Kornwestheim, Germany, which is installed in BMW`s N43 series four-cylinder petrol motors, is exposed to a combination of very high mechanical, thermal and chemical stresses. To enable this complex part to withstand the application`s demanding requirements dependably over long periods, Behr decided to make the housing out of DuPont Zytel HTN high-performance polyamide.
