Product Description

About electrical insulation board

JiuQiang refractory ceramic fiber panles are rigid products made from ceramic fiber which is vacuum formed with organic and inorganic binders, with or without mineral fillers. These are manufactured over a wide range of grades densities and hardnesses.

The boards are featured with high temperature stability, low thermal conductivity, even density, and excellent resistance against thermal shock and chemical attack. They can be used as individual component of furnace linings or as hard hot face layer as backup insulation.

Advantages of electrical insulation board

* Low heat storage and low thermal conductivity

* High compression strength

* Non –fragile materials and good toughness

* Accurate dimension and good planeness

* structure homogeneity and easy machining

* Easy to install

* Continual production, even fiber with stable property

* Excellent heat stability and thermal shock resistance

Application of electrical insulation board

1.Petrochemical process heater refractory fiber lining
2.Heat treating furnace or intermittent (shuttle) kiln hot face lining
3.General furnace backup insulation
4.Heat seals for kiln car or furnace door
5.Electrical insulator
6.High temperature acoustic
7.Fire protection
