Product Description

 

Mica board is an insulating material made by bonding, heating, and pressing mica paper and silicone adhesive. The mica content is about 90%, and the silicone adhesive content is 10%. Mica board has excellent insulation performance and high temperature resistance, with a fire resistance temperature of up to 500 ºC~750 ºC, and can still maintain its performance at high temperatures. In addition, mica board also has characteristics such as low thermal conductivity, oil and corrosion resistance, environmental friendliness and non toxicity, making it a substitute for asbestos. 1

Mica board is widely used in fields such as electronics, electrical appliances, aerospace, etc. In the field of electronics, mica plates are used to manufacture various electronic devices; In the field of electrical appliances, it is used to manufacture household appliances such as refrigerators, washing machines, etc; In the aerospace field, mica board is used to manufacture aircraft and satellites. Mica board has good processing performance and can be processed into various shapes without delamination, making it suitable for various industrial and electronic applications.

Properties for mica plate
Relative to general insulation material, the prominent advantages of the flexible mica plate are:
Excellent insulating properties at high temperature: At 500-1000ºC operating ambient temperature, the voltage breakdown resistance is 15KV/mm;Good tensile property:
It can be processed into a variety of shapes without layer separation;
Excellent environmental protection performance: The product contains no asbestos, and has less smoke and odors, even smokeless and odorless when heating;
Excellent acid and alkali resistance, and oil resistance.

FAQ
Q1:Are you trading company or manufacturer ?
We are a manufacturer, We have our own workshop producing electrical insulation polyimide film..
Q2: Can you send samples for testing?
A4size Samples are free supplied, customers just need to pay a litter shipping charge.
Q3: How can you guarantee the quality of mass goods is same as the sample sent to me before?
We kept another same sample and marked on company when we sent to customer. So our production 
will be based on and also we will test the product before shipment.
Q4: Which package do you use?
Package is important part to avoid goods breaking in transportation. We will choose suitable packing depend on materials.
