Detailed introduction
Mica board is a hard or soft board-like insulating material made of mica paper and high-performance silicone resin through bonding, heating and pressing. The mica content is about 90%, and the silicone resin content is 10%. ...
5660-S series soft mica board, also known as glued mica paper, has good elasticity and flexibility at room temperature, and can be curled into various shapes as required. Customers can choose products with different toughness according to their needs. For example, the semi-flex board used in hair dryers is one of them. Changfeng soft mica board can be folded dozens of times repeatedly without breaking. We can also increase the voltage capacity to 1-2 times the conventional standard value according to customer needs.
5660-S can be used as cover sheet, separator sheet, insulation sheet or high temperature resistant sealing material.
Common applications include hot air guns, induction furnaces, motors, transformers, etc. To
Type
According to different mica paper:
◆ 5660-S1: Muscovite soft board
◆ 5660-S3: Phlogopite soft board
Features Compared with general insulating materials, the outstanding advantages of soft mica board are:
◆Excellent insulation performance at high temperature. In the 500-1000℃ environment, the voltage breakdown resistance index still maintains 15KV/mm;
◆It has good tensile properties and can be processed into various shapes without delamination;
◆Excellent environmental protection performance, the product does not contain asbestos, has less smoke and odor when heated, even smokeless and tasteless;
◆It has excellent acid resistance, alkali resistance and oil resistance.
Specifications Thickness: 0.1mm 0.15mm 0.2mm~3.0mm
◆Length×Width: 1000×600mm 1000×1200mm 1000×2400mm Note: Products with thickness below 2.0mm can be formed by stamping, and those with thickness above 2.0mm need to be processed by turning, milling, drilling, etc. To
Packaging Generally, 50 kg is a package, sealed with plastic film, and then packed in a carton. When exporting, use fumigation-free trays, packed according to each tray <1000KG, or use iron boxes for protection. To
Use and storage Store in a dry, moisture-proof room temperature, and there is no limit on the use period.
