Aluminiumoxid-Keramik

As 95% of Alumina or steatite,ceramic parts of thermostat often are widely used in some electric appliances and electric refrigeration ventilation,such as Drinking fountains,Water heaters,Refrigerators.and Air-conditioning.After the producs go through from the more than 1,000-degree temperature firing,their strength,insulation properties,heat resistance and temperature sensitivity are very stable.Because of their low-cost and high volume production,they have replaced the traditional bakelite and plastic products. The ceramic thermostat of XinXing totally accord wih the standard of ROHS,and does not conain any harmful substances.
