Product Description
Band Heater Parts Steatite Ceramic Beads 1 Hole to 8 Holes
Introduction
Alumina ceramics is the most widely used fine ceramics material. This material has superb material characteristics such as high electrical insulation, high mechanical strength, high wear and chemical resistance. Due to the important combination of properties, we have thoroughly researched the behaviour and characteristics of our Alumina products to give you the best possible component.
Characteristics:
1). Excellent insulation ,security , long working life .
2). Precise grinding and polishing.
3). Excellent heat radiation, small size ,more environmental and energy-efficient .
4). good thermal conductivity
5). large specific heat capacity
6). low pressure drop
7). good heat-shock resisting ability
8). Working temperature: 600ºC-1200ºC

Steatite
Steatite is lower in cost than Alumina but offers reduced mechanical properties. However Steatite has very good electrical resistance properties, which are retained at high temperatures, along with moderate mechanical strength and temperature resistance. It has been used in electrical insulation for many years in both large-scale electrical systems and electronic and domestic appliances.
Characteristics:
Good to excellent electrical properties
High resistivity
Very low dielectric loss factor
Moderate strength
Low density
Application :
1). Gas cooker,Water heater,Gas oven, Gas boiler,Air-conditioning and so on.
2). As ceramic parts of flexible pad and channel heaters at operations of pre and postweld heat treatment; Welding process, stress-relieving, pre-heating & post heating, other resistance-heating environment
3). halogen lamps, high and low pressure uv lamps, mercury lamps, uv lamp holders and heating tubes.
4). high-power electrical applicance and all kinds of insulation device.
