Product Description

Alumina Ceramic Insulator /Electrical Insulation Rod For Oxygen Sensor

 

1. Description:

Typically used in ovens and furnaces, these are the most efficient of our rigid high-temperature insulation sheets. Please note that they require special care when installing since the crumbly material is difficult to work with and will crack easily. Sheets lose strength over time and are intended to be installed behind another facing or insulation material. They are flame resistant, meeting ASTM E84 0/0 for flame and smoke. Insulation performs best at temperatures above 1000° F.

 

2. Feature Advantages:

1) High compressive strength.

2) Good advanced ceramic materials

3) High welding sealing performance

4) Good wear resistance

5) Stiffness texture

6) Widely apply for automotive ceramic sensor , ceramic heater ,electric heating
