 Product description:
Polycrystalline mullite fibre cover piece is made of polycrystalline mullite fibre finishing cutting, compressed by the special craft. Do not contain any bond or other ingredients, has excellent elasticity and flexibility, the highest temperature can reach 1600 ¡æ. They in the oxidizing atmosphere, neutral atmosphere or partial reduction atmosphere under this temperature for a long time, still can maintain its original toughness, strength, softness and fiber structure, do not contain slag ball, can be used by all sorts of the hot side of high temperature industrial kiln lining paste, has a particularly strong heat insulation performance, is the crystallization of high and new technology industrialization.
