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 is the electrical performance of insulating materials: The electrical insulating material is a material that is electrically insulated from the device and has a certain mechanical strength, typically having a resistivity of 106 to 1019.cm. Their function in electrical technology is as follows: 1 Insulate the conductor from the other parts; 2 Separate the conductors of different potentials 3 Provide the conditions for the energy storage of the capacitor 4 Improve the potential gradient in the high voltage electric field.

Q: Brass is not an insulating material?: Brass is not insulating material. On the contrary is the brass is conductive material. Brass texture hard, can not bend. No copper flexibility is good, so brass can only do a fixed copper conductive use.

Q: What kind of insulation is the insulating: Now most of the aluminum substrate in the insulating layer or epoxy (I do this, do not mention my company name, so that I advertise). Epoxy can be modified, and then through the surface treatment of the thermal filler, in the cross-linked when the formation of a most conducive to the heat transfer structure, so as to achieve the purpose of high thermal conductivity.

Q: Insulation material and the definition of the role of the best professional insulation materials website for my reference: According to the national standard GB2900.5 provides the definition of insulating material is: "used to make the device in the electrical insulation of the material." That is, to prevent the current through the material.

Q: What insulating materials are used for transformers: With the largest number of cardboard, as well as laminated wood, insulating paper, transformer oil, large oil-immersed transformers are mostly oil - paper insulation.

Q: What insulating material is used for high voltage cables: Etc., can withstand mechanical force and a certain tension. YJLV32 aluminum core XLPE insulated fine steel wire armored PVC sheathed power cable YJV33 copper core XLPE insulated fine steel wire armored PVC sheathed power cable YJLV33 aluminum core XLPE insulated steel tape armored PVC sheathed power cable

Q: What are the gas insulation materials?: The relative breakdown strength of air (at air 1) at the standard pressure (101335Pa) is as follows: nitrogen, 1; hydrogen, 0.5; carbon dioxide, 0.9; sulfur hexafluoride, 2.5; freon-12,2.7 The

Q: What is the DMD insulation material?: DMD (Dacron / Mylar / Dacron) full name polyester film polyester fiber non-woven soft composite foil, is a two-layer polyester non-woven fabric in the middle of a layer of insulated polyester film composite made of three insulation materials.

Q: What are the commonly used insulating materials?: Mainly used for motor, electrical winding insulation, switch the bottom plate and insulators, etc. Organic insulation materials are: shellac, resin, rubber, cotton yarn, paper, linen, rayon,

Q: What is the thermal aging and electrical aging of insulating materials?: Environmental aging, also known as atmospheric aging, is due to ultraviolet light, ozone, salt spray, acid and other factors caused by pollution of chemical aging, which is the main reason for ultraviolet light. Thermal aging more common in low-voltage electrical appliances, the mechanism is under the action of temperature, the insulating material in some volatile components escape, the internal components of oxidative cracking, thermal cracking, hydrolysis, molecular chain polymerization and other chemical changes, and gradually lose insulation properties.
