What Are The Key Properties Of Mica?

Mica is a naturally occurring element with properties that make it an excellent industrial insulation material. A wide range of mica insulation products is used in various industries. This element is a group of silicate minerals found in igneous rocks in crystal form. It is used for insulation purposes both in its natural form and its built-up form after processing.



 Here is a brief explanation of each key property:

 

Thermal insulation

 Mica offers unbeatable thermal insulation. Mica sheets are used for thermal insulation in various industries, including aerospace, automotive, foundry and steel, and consumer appliances.


 


Sheets made of muscovite mica are stable up to 500 °C (932 °F) whereas phlogopite mica sheets are stable up to 900 °C (1,650 °F).

 

Due to its advanced thermal insulation abilities, mica forms a wide range of insulation products. These include rigid mica sheets, which are used in furnace construction; flexible mica sheets, which are used in the aerospace and automotive industries; mica laminates, which are used as flame-retardant barriers; and mica gasket and mica insulation, which used for the thermal insulation of automotive components. 

 

Electric insulation



 

Due to its exceptional dielectric capability, a vast range of mica-based products is used for electric insulation in various industries. Mica tape is the most common product used in the electrical industry for the electric and thermal insulation of high voltage wires. Mica is also used in wiring for circuits, transformers, and starter motors. It also forms key components of circuit boards.       

 Ability to break into thin sheets

 Mica can easily break into thin sheets and can be split into sheets of thickness between 0.025mm to 0.125mm without losing its electrical properties and rigidity. This makes it ideal for making a range of insulation products in the aerospace industry, automotive industry, and consumer appliances.

 Chemically inert

 Mica is chemically inert and therefore does not react with other elements. This property makes mica non-combustible. Additionally, mica halogen-free and does not produce harmful gases on burning. This makes it ideal to be used as the insulation material of wires. In case of unexpected events, mica can delay the spread of fire and reduce the release of toxic gases.   

 Lightweight 

Mica is light in weight, making it an ideal element for making a range of thermal and electrical insulation products for the aerospace and transportation industry. Mica minerals can be processed to form a variety of lightweight insulation products.

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...
