Steatite Ceramic

Steatite is a crystalline form of magnesium silicate. It is an material with excellent insulating and mechanical performance, which can work safely at temperatures up to 1000.  It is widely used at applications, such as electric connection, high temperature insulation, resistor cores and casings, and insulators for home appliances. 

Features &Advantages 

1. Good dielectric strength

 2. Tracking resistant

 3. Heat resistance up to 1000C

 4. High mechanical strength

 5. Resistant to UV radiation
