How Can Mica Be Adapted and Used for Various Applications?

Mica is a very versatile and flexible material. Due to specific electrical, physical, and thermal properties, it makes for an ideal insulation material. Thanks to mica’s versatility, it can be applied used in different applications through cutting, shaping, and combining with other substances to create unique insulation solutions. 

There are 3 ways in which mica is usually adapted for use in various applications.



Shaped Mica

Mica has high tensile strength and is formed in thin sheets, which can easily be cut and shaped. Techniques such as milling, laser cutting, and clicker pressing allow mica to be produced in large quantities in precise shapes and exact measurements. Shaped mica products are used in high voltage transformers and switchgear applications in bulk. In addition, pure mica can withstand up to 2000kV per mm, making it ideal for high voltage applications. 

Shaped mica is becoming increasingly popular in the automotive industry. The widespread movement towards electric vehicles is forcing innovation in battery technology. Mica shields are used in automotive industries to provide insulation that slows the process of thermal runaway. 

Rolled Mica

Mica has great thermal properties. Pure phlogopite mica can withstand up to 1,000 C, but it also bonds with other insulating materials to form a stronger and more effective insulation material. In rolled mica, mica is combined into a laminate with another insulating material and produced in rolls. It can be 0.4mm to 3.3mm thick. Mica is usually combined with glass fabrics, glass tissue, silicone, and Calcium Magnesium Silicate to increase the material's temperature. 

This kind of product is usually used in induction furnaces. It is extremely easy to install due to its thin and flexible structure. In addition, due to its thermal properties and durability, it helps extend the life of the furnace lining. 


Rigid Mica and Formed Components

Mica is a flexible material, but it also has high tensile, elastic tenacity, and compressive strength.  This means it is durable, strong, and provides structural and insulating support. It also means that mica can easily be incorporated into rigid forms and applications. 

Mica tubes are used in various appliances, like hair dryers, air blowers, and heat guns. It acts as an insulation sleeve and protects the core heating elements. Additionally, its superior electrical and thermal insulation can be used in larger electrical motors as well as smelt furnaces. 



Mica sheets are shaped around a form and function in the same ways as tubes. Both rigid mica tubes and mica sheets are specifically manufactured to be waterproof, which means they can withstand the elements and keep their insulation properties for a longer duration.

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. Axim h...

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, i...

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 accepte...
