General Characteristics & Applications of Mica sheets

Axim Mica offers different types of products composed of 90% mica in the forms of muscovite mica or phlogopite mica (magnesium silico-aluminate). Mica refers to a family of minerals characterized by its flake-like structure. Its thermal and dielectric properties, particularly, make it suitable for many applications, up to 1,000°C. Easy to machine and bond, it is an easy-to-use high-temperature solution.


Mica manufacturing


Mica is mined from natural deposits. Although fragmented or powdered mica is more common, only Mica sheets are of sufficient quality to produce effective products at high temperatures. Among the wide varieties of mica, two are used in high-temperature environments: phlogopite mica, whose magnesium content gives it a tint ranging from brown to green, and muscovite mica, which is more concentrated in aluminum, hence giving it a whitish color.

 

General characteristics of mica 


  • Health and security
  • Nontoxic
  • Storage as a non-hazardous product

Thermal characteristics


  • Peak temperature: 1000°C
  • Good resistance to high temperature
  • Low thermal conductivity
  • Incombustible

Mechanical characteristics


  • Pressure resistance
  • Permeability to high-frequency waves

Electrical Specifications


  • Electrical insulation
  • Resistance to electric arc and erosion
  • Good dielectric strength

Mica Applications 


  • Electrical insulation, i.e., Mica Battery Sleeves Thermal insulation
  • Forging press plates (reduction of heat loss)
  • Guides for bottles leaving the mold
  • Sealing of internal network connections for gas distribution
  • Construction of induction furnaces
  • Burner gasket, exhaust manifold, exchangers


Mica products

 

Technical composites


MC- 5000HT mica products are an excellent alternative to asbestos products for insulation. They are also used by the glass, ceramics, and metals industries for insulating induction or arc furnaces, injection presses, or electrical components. They come in two high-temperature variants: MC-5000HT plates and tubes.

 

Mica Cable Tape and paper


The ribbon consists of a thin mica paper made with phlogopite (90% mica) impregnated with a unique high-temperature binder and reinforced with glass-silk placed on one side of the mica. This binder decomposes at high temperatures without altering the electrical insulation properties of mica or generating toxic products. In addition, the product is incombustible thanks to the glass-silk.


Cotronics Adhesives


Final Advanced Materials offers, in collaboration with Cotronics high, temperature adhesives based on mica. These technical products are incredibly flame resistant and can be used as a versatile sealing paste.

 

Axim Mica provides you with the best quality mica materials & products to buy that conform to ISO 9001 guidelines. For any additional information, visit https://aximmica.com/ or call us at (516) 248-0045.

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...
