High Temperature Resistant 99.5% Al2O3 Alumina Ceramic Strips
Key words : Alumina Ceramic Strips
Mingrui 's Alumina Ceramic Strip provides the ability to withstand
higher temperatures (typically limited to 40 to 45 watts per square
inch, depending on the application). The heater consists of a
stainless steel sheath containing a high-temperature ceramic
insulating a nickel chrome wire coil. Magnesium oxide (MgO) is used
to fill any air pockets, thus providing the best heat transfer
possible.
The terminals are also constructed of stainless steel and are
securely anchored to prevent twisting out under normal conditions.
Several terminations are available, including water-resistance.
Features & Benefits
- High heat transfer rates and fast heat up
- Ceramic construction for higher temperatures
- Long life
- Large selection of lengths, sizes and terminations
- Low expansion characteristics
- 3-Phase available
- Distributed wattage available
High-quality Alumina Ceramic Strips (aluminum oxide Al2O3 99.9%, 99.7% and 96% and zirconia ZrO2) are
present in low and high pressure injection valves. These components
are equally vital in any other switching valve systems where inert
materials resistant to the harshest solvents are required.
Mingrui manufactures high quality Alumina Ceramic Strips, made out of High Purity Alumina (97%, 99,7% or 99,9%) and TZP
Zirconia ceramics for high and low pressure injection and selection
valves. Rotors and Stators are subject to intensive mechanical
stress and chemical aggression while having to maintain a perfectly
leak free adjustment between the two components. No leak, limited
stiction and low wear are the most important parameters to
guarantee long life and reliability to your valve. These can be
achieved by an adequate surface finish, a perfect flatness of the
surfaces in contact and a proper selection of the material. Every
application is different and Ceramaret will help you define the
parameters required for your particular valve. Ceramic Rotors and
Stators are used in valves for many high-tech applications, such as
HPLC, micro-HPLC, Medical, Industrial, etc.

Advantages of Alumina Ceramic Strips:
1. Isostatic pressed.
2. Fire resistance.
3. Superior mechnical strength.
4. High corrosion and wear resistance.
5. High Temperature Resistance.
6. Good Insulation Performance Precision.
7. Zirconia and alumina ceramic material.
They are high corrosion and wear resistance and strong impact
resistance and delivers 10 times longer working life than metal
plunger. They give a longer life to the sealed packing material.
Our Ceramic Strip heaters provide a dependable, versatile and
efficient heat source for a wide range of applications, such as:
- Heating air
- Injection and Extrusion dies
- Food tables and platens
They are available in many lengths. Whenever possible, please
provide a dimensional sketch of your requirements with your order.
