Characteristic

It is characterized in white appearance, smoothness, softness and elasticity, just like pledget. PMF is a polycrystalline mullite fiber in the existing form of mullite crystalling phase, with a unique structure, complicated manufacturing process and high technical content.

High temperature stability to 1600-1800C
Ideal for use as furnace insulation in sintering, heat treating and chemical thermal process systems
Non-Flammable
Excellent thermal shock resistance
Resistance to most chemical attack; it has excellent stability in acid metal slags and is insoluble in most acids
Resistance to oxidation and attack by furnace atmospheres
Resistance to abrasion
Good electrical resistivity
Excellent thermal stability
Can be used as insulation packing in furnace spaces and around furnace sight tubes & ports
Fill in expansion joints and masonry cracks inside of furnaces.
Recommended using temperature:In oxidizing or neutral atmosphere,100~250℃Recommended usingtemperature:In oxidizing or neutral atmosphere,100∽250℃lower than the maximum service temperature,In reductive atmosphere,200~350℃ lower than the maximum service temperature.
