Product description
HP5 phlogopite board adopts imported phlogopite raw material and imported high-temperature silicone resin glue to bond the hard plate-shaped insulating material formed by baking and pressing.

HP5 phlogopite board has superior electrical insulation performance and high temperature resistance, and is especially suitable for high-temperature insulation of domestic and imported industrial electric furnaces, power frequency furnaces, intermediate frequency furnaces, electric arc furnaces, etc. in steel, metallurgy and other industries, and as a substitute for asbestos. It is specially designed for electro-thermal mechanical applications with higher requirements for the following properties.

The product has passed UL safety certification, and the product implementation standard is IEC371-3-3. According to the different mica paper used, it can be divided into two types: phlogopite board and muscovite board. Product performance: Excellent high temperature resistance and insulation performance, the highest temperature resistance is up to 1100 ℃. …

Excellent electrical insulation performance, the voltage breakdown index of ordinary products is as high as 20KV/mm. Excellent bending strength and processing performance, the product has high bending strength and excellent toughness, and can be processed by lathes, milling machines, and drilling machines. Various special-shaped pieces without layering. …

Low thermal conductivity, excellent electrical insulation performance, oil and corrosion resistance, asbestos substitute. To

The company's regular product specifications are:> Length * Width: 1000 x 600 mm 1000 x 1200 mm 1000 x 2400mm 1200 x 2600mm 1200 x 2600mm

Various sizes of mica plates, washers, mica shaped parts can be processed according to customer requirements, and various parts can be produced according to drawings.

Thickness: 2mm, 3mm, 4mm, 5mm, 10mm, 20mm, 25mm, 30mm, …… 100mm 

Packaging Generally 50kg 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.
