Ceramic Board Mullite Ceramic Board Polycrystalline Mullite Ceramic Board

Product Description
Polycrystalline Mullite ceramic board 1700 for kilns and burners insulation

Polycrystalline Mullite Ceramic Fiber Board (PMF) a novel super-light high-temperature refractory fiber in the world, are made from high pure ceramic fiber by advanced vacuum formed machines,with use temperature of 1800 degrees to 1700 degrees, more mechanical strength and average density compared with those boards formed by traditional machine.polycrystalline alumina fiber is currently at home and abroad the latest ultra-lightweight high-temperature fire-resistant fiber, It can achieve energy efficiency increase, extend furnace life, the purpose of improving the working environment. So widely used in metallurgy, machinery, electronics, ceramics, chemicals, aerospace and other high-temperature industrial furnaces and other thermal equipment, lined with insulation.
