Industry Information

Ceramic Insulators

Ceramic insulators are used for a wide variety of applications due to their very good electrical conductivity. Known as electrical ceramics, ceramic insulators provide insulation in situations where high temperature or electricity is present due to their non-mineral makeup. Ceramic insulators are also advantageous because of their cost-effectiveness and practicality.

Ceramics are one of the best electrical insulators because of their stability and non-conducting properties. Highly arc and track resistant, they are dimensionally stable at elevated temperatures, resisting burn. Ceramic insulators are also able to resist heat, chemicals, weather, and bacteria without allowing them to affect their properties or alter their structure. Ceramic insulators also offer dimensional stability and rigidity.

Ceramic insulators offer applications in many different fields. Because of their inherent characteristics, ceramic insulators are ideal for micro-wave applications. Ceramic insulators also have many applications in the foundry and refractory industries because they can withstand thermal shock, even molten metal, and still maintain their rigidity. The aerospace, automotive, marine, medical, and transportation industries often use ceramic insulators for various purposes as well.
