Themal feature. Insulated glass can reduce the heat conductivity coefficient U, or get it down furthermore if filled with inert gas.
可有效降低传热系数U值，若充入惰性气体可进一步降低传热系数。
The utility model is not only heat-resistant, with high insulating strength and low heat conductivity coefficient, but also easy to machine, and can be widely used on electric heating apparatuses.
本实用新 型不但耐热性能好，绝缘强度高、导热系数低，而且便于机械加工，可广泛 用于电热设备上。
