6 Amazing Benefits of Mica Glass Tape Insulation

Mica glass tape insulation is an incredible material for high-temperature applications across numerous industries. Made from mica splits bonded to fiberglass fabric with adhesive binders, this insulation tape can withstand continuous use temperatures over 1000°F.


If you need insulation that can handle extreme heat and resist fire, abuse, and corrosion, mica glass tape is an optimal solution. Keep reading to learn the six key benefits of mica glass tape insulation.

  1. Withstands Very High Temperatures

The primary advantage of mica tape insulation is its ability to withstand extremely high temperatures. The mica content in the tape can resist continuous heat up to 1100°F to 1200°F. The fiberglass component increases the tensile strength and tear resistance.

Mica is a naturally occurring silicate mineral with excellent heat resistance properties due to its unique layered structure. Combining mica with fiberglass in an insulation tape creates a barrier that can protect underlying components from intense heat exposure.

  1. Excellent Electrical Insulation Properties

In addition to thermal resistance, mica glass tape provides excellent electrical insulation. Mica has a high dielectric strength, strongly resisting electric current flow. This makes mica glass tape ideal for insulating electrified components like coils, cables, and heating elements.

The electrical resistance ensures the protected components will operate safely and efficiently without power leaks or short circuits. Mica glass tape maintains its dielectric strength in dry and humid conditions for reliable insulation.

  1. Mica Glass Tape Insulation Withstands Thermal Shock

Unlike some materials, mica glass tape holds up exceptionally well to repeated, intense temperature fluctuations. When an insulated component undergoes rapid heating and cooling cycles, it creates massive thermal stresses.

Materials that can't handle the temperature swings will crack or crumble. However, the mica and fiberglass in mica glass tape resist thermal shock failure. This durability makes the tape well-suited for applications with frequent thermal cycling.

  1. Chemically Inert and Corrosion-resistant

Mica glass tape insulation offers exceptional chemical and moisture resistance. The mica, fiberglass, and adhesive binders are non-reactive and inert. The tape's insulation properties remain unaffected when exposed to oils, solvents, moisture, and other corrosive substances.

The tape provides lasting protection in harsh environmental conditions - from salt air to exhaust fumes. By insulating components from destructive chemicals and moisture, mica glass tape prevents costly corrosion damage for longer service life.

  1. Flexible and Conformable

Unlike rigid insulators, mica glass tape is flexible and conformable, allowing it to adapt to different component shapes and configurations. The tape can be wrapped around curved surfaces, molded into recessed areas, and layered.

With flexible glass mica tape, intricate or irregularly shaped components and systems can be adequately insulated. The tape is available in various thicknesses and widths to accommodate insulation needs. Custom slit widths are also available for precise insulation coverage.

  1. Lightweight and Easy to Install

Mica glass tape insulation delivers outstanding performance in a lightweight, easy-to-handle tape format. The tape's flexible design makes installation faster and more straightforward than rigid insulators requiring cutting or complex mounting.

Since mica glass tape comes in a roll format, it can be quickly wrapped around components needing insulation. No special tools or setup is required. The tape can be installed on-site to save time and labor costs for removing or pre-insulating components off-site.

Key Applications of Mica Glass Tape Insulation

With its unbeatable thermal properties and dielectric strength, mica glass tape has become a staple insulation material for:

  • Power generation equipment - transformers, turbine components, boilers, generators

  • Heating elements - strip heaters, tubular heaters, ceramic fiber heaters

  • Electrical coils and windings - motors, generators, solenoids

  • Wiring harnesses and cables

  • Engine and exhaust components

  • Appliances - ovens, stoves, heaters

  • Furnaces and kilns

How is Mica Used for Electric Vehicle Battery Insulation?

Image
Electric vehicles are the future. The ban on petrol and diesel vehicles is going to roll out by 2030. Thus, the transition to electric vehicles is inevitable. Electric vehicle technology is still in the early stages and thus expensive.  Apart from making efficient battery systems, manufacturers need to ensure that electric vehicle battery systems are safe. The electric vehicle battery pack needs to be insulated thermally and electrically to ensure safety. In this post, we will look at how mica material is used for electric vehicle battery insulation.   Mica Battery Pack Insulation  Mica battery pack insulation is used as a high-temperature incombustible barrier around battery packs and to electrically insulate the battery pack from other critical components of an electric vehicle. Axim Mica mica car battery pack insulation comes with the UL-94 rating and CE and ROHS certifications. You can partner with Axim Mica to design a customized battery pack insulation.

A Short Guide on Two Popular Types of Mica Sheets!

Image
Mica is a naturally occurring material that comes in 37 different varieties.  However, only two forms of mica—phlogopite and muscovite—out of the 37 variants are utilized for industrial insulating purposes. Although they come in sheet form, they must first be transformed into powder before being used to create a variety of mica industrial insulation products. Each of these two forms of mica has characteristics that make them suited for a variety of uses in numerous sectors. Read out the below blog to learn about two popular types of micasheets . Types of Mica sheets   Phlogopite Mica Sheets:   The mica sheets that remain stable up to 900°C are known as phlogopite mica sheets. They come in both flexible and rigid forms. The thermal insulation properties of phlogopite mica sheets are different from muscovite mica sheets. Phlogopite mica, out of all the different types of mica, offers the best thermal insulating properties. There are a variety of colors, including amber

What is the role of safety certifications of mica sheets in the industry?

Image
Mica sheets are used in various industries for thermal and electrical insulation applications. They are used at high operating temperatures up to 1600 degree cel sius and in high voltage environments. Therefore, it is very important to ensure that mica sheets are safe for use. That’s where the role of  mica sheets  comes into play. The certifications are gained by rigorously testing the product under controlled conditions. Regarding mica sheets, the UL rating is the global industrial safety standard.  Other region-specific fire resistance classifications, such as BS 479 (class 1) and NBN 21-203 (A1), are also used to approve thermal and electrical insulation products. In this post, we will focus on the UL-rating of mica sheets. What are UL standards for safety? UL is a global safety certification company that certifies a wide range of products used in both industrial and commercial applications. If a product is listed or UL certified, the product is globally accepted as safe for
