• High application temperature: maximum 1200 0C in air
• High power at unit surface, up to 25 W/cm2
• Small thermal inertia and fast heating
• Acid and alkali corrosion resistance
• Small size
• Long life

Typical applications include:

• Die heater
• Packaging machinery heater
• Tobacco equipment heater
• Industrial heating equipment
• Hot and cold drink machine heater
