How to Choice Good Thermal Resistance Mica Tape?


It is important to understand what Mica is? Mica is a group of minerals – famous around the globe for its outstanding thermal and electrical resistance capabilities. Moreover, each mica crystal can easily be split into fragile elastic plates.

 

Mica tapes have great resistance to chemical, electrical, and heat. That acts as an upper hand in terms of preference and usage. Mica tape is made of mica paper, natural phlogopite (magnesium silicoaluminate), synthetic Mica, or calcined muscovite. Then with the help of a special resin, it glues to the substrate of polyethylene or glass fiber.

 

Dimensions of Mica Tapes

Usually, mica tape has a thickness of approx. 0.15mm. It is packaged in the length of 300-2000 linear meters. Such products are available in many custom sizes and width from 4.5mm to 1000mm. In addition, customized traverse wound spools and pads are readily available off the shelf.

 

Fire Resistance

Mica mineral has quite exceptional flame-resistant characteristics. This property makes it popular in the mica cable industry.

 

Chemical Resistance

Mica has a great water-resistant property which is quite impressive. In addition, mica tape is chemically neutral, entirely free of halogens, and non-toxic. Its properties remain unchanged up to radiation exposure of 109 Rad. Also, it has excellent resistance to acids and bases, including solvents and mineral oils.

 

Some Other Properties of Mica Tapes

  • high thermal resistance - good fire resistance.
  • Non-flammable does not contain asbestos and does not produce toxic gases.
  • Very good resistance to electrical breakdown and corona discharge.
  • Excellent tensile strength, anti-shock.

 

Applications of Mica Tapes

The following are some of the best applications where there is a great demand for mica tapes:

  • insulation of electrical cables and coils
  • multi-story buildings,
  • power stations,
  • industry plants,
  • subways,
  • computer centers,
  • aerospace units,
  • telecommunication centers,
  • ships,
  • Military facilities.

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...
