ABOUT
Introduction
The mica strip heaters manufactured by Tempsens Instruments are precision-engineered to ensure reliable, uniform heating to surfaces across many industries. The mica strip heaters are constructed from a nickel-chromium resistance heating ribbon wound onto high-quality mica insulating material, wrapped, and then encased in a stainless steel sheath, thus, providing a consistent level of thermal performance for each mica strip heater up to 250° C (482° F) maximum temperature. As a certified manufacturer of mica heaters, Tempsens offers standard or custom-cut mica heaters. All mica strip heaters manufactured by Tempsens are certified to ISO 14001:2015, ISO 45001:2018, UL, and CE. They have a maximum watt density of 28 W/in2; maximum voltage of 480V; and multiple termination options. Mica strip heaters are the ideal choice for low and medium temperature industrial heating needs.
About Mica Strip Heater
Features and Benefits of Mica Strip Heater
- Able to withstand high temperatures up to 250 degrees Celsius, the stainless steel sheath will allow for long life in challenging conditions with space limitations.
- The nickel-chromium alloy resistance ribbon is wound around a mica strip, providing even distribution of surface heat.
- The heaters can be manufactured in a minimum width of 5/8” and in a variety of lengths with or without mounting tabs.
- Available with screw or lead wire type terminations in a variety of configurations (end-to-end, parallel, offset and tandem).
- The high quality mica insulation provides high electrical safety and good thermal conductivity properties.
- Stainless steel can withstand corrosion and vibration, making these products ideal for use in tough environments.
- Light weight flat design with optional mounting tabs provides the fastest and most economical means to install.
- Wattage Tolerance +5% and -10%, Resistance Tolerance +10% and -5%.

Applications of Mica Strip Heater
- Blow Molding: A technique that ensures uniform temperatures in the cylinder and platten for creating a consistent process of mold-making with plastics.
- Compression Molding: An application that provides an even distribution of temperature to molds for processing rubber or other composites.
- Screen exchanger heating zone: Used in in injection molding to ensure consistent, efficient heating that prevents plastic from hardening within the filtration unit.
- Packaging and Sealing: Utilized in heat seal bars and heat seal equipment for creating a reliable bond between materials; such as between plastic and paper.
- Food Warming Equipment: Provides safe, consistent heating to commercial food warmers and their respective display units.
- Hot Plates and Ovens: A very good surface heat source for laboratory ovens and industrial hot plates.
- Heating Inks & Adhesives: Maintains a consistent fluid viscosity in either printing or bonding applications
- Laboratory Equipment: Controls and repeatable heating method(s) for analytical or testing equipment.
- Heating Rubber Platens: Provides a very efficient method of heating through conduction on flat surfaces, in either a press or a vulcanizing machine.
Types of Mica Strip Heaters
- Screw Termination: Both Ends: Both ends of the terminal board are wired from opposite sides of the terminal, and are also available with or without mounting tabs for rigid wire termination.
- Screw Termination: Parallel: Both screw terminals are on the same side of the terminal board and are suitable for installing on space-constrained panels.
- Screw Termination: Offset: The screw terminals are staggered for more flexible wiring layouts.
- Screw Termination: Tandem: Allows for extended wiring options to be used with multi-zone heating systems.
- Lead Wire Termination: Both Ends/Parallel: Flexible lead wire exit for use in applications which require remote connection locations for the heating element.
- Special Shapes: Custom heating elements (mica strip uses) to meet the customer’s design specifications for disc-shaped, ring-shaped or irregularly shaped.

FAQ
Frequently Asked Questions
Find answers to frequently asked questions related to Mica Strip Heater.
A Mica strip heater is a flat rectangular heater that can be used to heat platens, flat molds or apply heat over the surfaces of panels. A Band heater is a cylindrical-shaped heater designed to be wrapped around a barrel or pipe. Mica strip heaters have superior surface contact with the object being heated and provide better uniformity of heating for a particular application.
Mica strip heaters are built with a stainless-steel protection that prevents corrosion, however these types of heaters should not come into direct contact with water (e.g., be submerged). A Terminal Box accessory would be a great way to protect electrical connections from any dripping or overflow in a potentially wet environment.
Wattage is calculated based on the surface area to be heated, the required temperature rise, and heat-up time. The mica strip heating element supports up to 28 W/in² maximum watt density. For custom wattage calculations, contact the Tempsens factory with your application details.
