Thick mica plate
The ultra-thick hard mica plate is a high-strength plate-like insulating material with a thickness range of 3mm to 100mm. The ultra-thick hard mica plate has excellent heat insulation properties, with a fire resistance temperature of up to 750℃, and low thermal conductivity; it is oil-resistant, corrosion-resistant, environmentally friendly, and non-toxic, making it an excellent substitute for asbestos. Moreover, it has good bending strength and can be processed into various special-shaped parts. It is widely used in fields such as chemical machinery, metallurgy, electronics, and high-speed locomotives.
