1. Introductions:

Mica is a rigid substrate able to withstand very high temperatures and are suited for applications up to 500°F (260°C). Mica heating elementsoffer several distinct advantages over other flexible heater technologies, including extremely low leakage, lower material costs, and higher operating temperatures. Our mica heating element is made by detail order requirments.

Mica plate is made of mica paper with high performance organic silicon resin. After heating and pressing, the mica plate can be made into rigid or flexible insulating plates. The mica content is about 90% and the organic silicon resin content is 10%.

2. Main features of Mica Parts:

Rigid mica plates are featured with high strength, good performance, less smoke, less odor etc. This series mica plates are used mainly in household appliances (toaster ovens, microwave ovens, warm air blowers, hair dryers, electric iron etc.), metallurgy (such as line frequency furnaces, medium frequency furnaces, electric arc furnace, etc.), medical equipment and other industries, used as the heating support, lining plate and partition plate of the electric appliances described above.

3. Applications:

Typical applications of mica heating elements are air heaters, enclosure systems, food service equipment, process and packaging equipment.

FAQ

We have organized several common questions for our clients,may help you sincerely：

--------What is the use of mica parts?

Mica laminate and washers made of our own high quality mica plates are used for home appliances, electro-magnets, micro-sensitive control gear etc

---------Which type of mica parts we can produce?

1. Rigid mica parts or Flexible mica parts

2. Muscovite mica parts or phlogopite mica parts

3. Thin mica parts or thick mica parts

4. All the special sized mica parts need drawing.

----------what advantages of mica parts?

1. Good high voltage insulation materials

2. Do not easily break up

3. Easily produce special size

Q: What kind of insulation is the insulating: Insulation is the core technology of aluminum substrate. Currently on the market most of the aluminum substrate insulation layer using epoxy resin, the advantages of this type of insulation is: good adhesion; drawback is: thermal resistance, dielectric strength is limited, it is difficult to meet the safety requirements. Such aluminum substrates are only suitable for low power density applications. High-end aluminum substrate insulation layer is generally composed of high thermal conductivity and high insulation ceramic powder filled with special polymer composition.

Q: Insulation material and the definition of the role of the best professional insulation materials website for my reference: Electrical strength is the breakdown of the voltage between the voltage and the two electrodes subjected to the applied voltage under the specified conditions, that is, the breakdown voltage per unit thickness. For insulating materials, the general breakdown voltage, electrical strength of the value of the higher the better. 4, tensile strength: in the tensile test, the sample to withstand the maximum tensile stress. It is the most widely used and tested test of the mechanical properties of insulating materials. 5, Flammability: refers to the insulation material in contact with the flame to resist combustion or leave the flame to prevent the ability to continue to burn. With the increasing use of insulating materials, its flammability requirements are more important, people through various means to improve and improve the insulation

Q: What insulating material is used for high voltage cables: High - pressure rubber sheathed flexible cable UGF: Model and name: UGF - 6000V mine rubber flexible cable UG - 6000V mine rubber flexible cable. Implementation of the standard: TL / J30-94. UGF cable Uses: AC rated voltage 6kv and below mobile power distribution equipment and mining machinery; lifting transport machinery.

Q: What insulating materials do you need for power tools?: Additional insulation: insulation between the rotor core and the mandrel (insulating plastic powder), between the stator core and the plastic housing shell, is the additional insulation withstand voltage of 2500V;

Q: What insulating materials are used for high frequency transformers?: Where the water is mainly a resin and solvent or resin, oil and solvent composition, is based on polymer polymer, under certain conditions can be cured into an insulating film or insulation of the important insulation material, applied to high-frequency transformers After the surface, the solvent evaporates, the resin or the resin and the oil form a smooth film, showing the original pattern of the object. Easy to dry and durable, and can acid and oil.

Q: What is the insulating material in the middle of the connecting wire?: With a transparent tape isolation, with hot melt adhesive fixed thread, with heat shrink tube insulation, a lot of ways ah.

Q: What are the gas insulation materials?: Gas insulation material refers to air, nitrogen, sulfur hexafluoride and other gases

Q: What is the DMD insulation material?: DMD insulating paper, the product is a layer of polyester film coated with adhesive, one side for the polyester fiber non-woven composite, calendering from a composite insulation products, referred to as DMD.

Q: What are the commonly used insulating materials?: Commonly used inorganic insulation materials are: mica, asbestos, marble, porcelain, glass, sulfur and so on, which can be divided into inorganic insulating materials, organic insulating materials and mixed insulating materials.

Q: What is the thermal aging and electrical aging of insulating materials?: Insulation materials in electrical equipment during the operation, due to the long-term effects of various factors, there will be a series of irreversible physical and chemical changes, resulting in its electrical performance and mechanical properties decline, commonly known as aging. There are many factors that affect the aging of insulating materials. The main aging forms are environmental aging, heat aging and electrical aging.
