Mica Insulated Band Heaters for Efficient Barrel & Process Heating

Reliable, Economical Heating for Industrial Equipment

Mica insulated band heaters are widely used for heating barrels, pipes, tanks, and cylindrical surfaces where consistent temperature control is essential. Designed with high-grade mica insulation and precision resistance winding, these heaters provide fast heat-up, excellent thermal conductivity, and dependable long-term performance.

With sheath temperatures reaching up to 900°F, mica band heaters are especially popular in the plastics industry for injection molding and extrusion applications.

Why Choose Our Mica Insulated Band Heaters

• Excellent Heat Transfer - High-grade mica insulation ensures efficient thermal conductivity
• Uniform Temperature Distribution - Optimized resistance winding minimizes hot spots
• High Operating Temperatures - Sheath temperatures up to 900°F
• Secure Barrel Grip - Designed to tighten on the barrel when energized for better contact
• Cost-Effective Solution - Ideal balance of performance and affordability
• Flexible Configurations - Accommodates holes, cut-outs, and multiple termination styles

Engineered for Maximum Heater Life

Each mica band heater is carefully rounded and formed to maximize surface-to-surface contact with the barrel. The external metallic sheath is made from a special alloy that expands less than the heated barrel, causing the heater to grip tighter during operation. This improved contact enhances heat transfer and significantly extends heater life.
