Home Refractory Ceramic Fiber (RCF) Vacuum Formed Shapes

Vacuum Formed Shapes

Vacuum Formed Shapes are made of high-quality ceramic fiber cotton by adopting the technique of vacuum forming. The purpose of making these products is to meet the special requirements of insulation in industrial field. Various products need to have specialized molds according to their unique shape and size for meeting customers’ requirements. All Vacuum formed shapes have a lower shrinkage within applicable temperature, and can maintain the characteristics such as insulation, lightweight, etc. During the period of using the products, they won’t be eroded by lots of molten metal.

Vacuum Formed Shapes are in accordance with the requirements of users design by using loose cotton wet vacuum suction forming after drying, the calcine bulk density, different specifications, models, performance of various kinds of fiber products. Because of its excellent production equipment and the guarantee of stable raw material, products in addition to satisfy the requirement of the user various complex thermal, each product is as elegant handicraft.

Product features:
> Excellent compressive strength, bending strength;
> Low thermal conductivity;
> Thermal shock resistance;
>  High dimensional accuracy;
> Heating, cooling rapidly;
>  Air flow scouring resistance;
>  Resistance to thermal shock.

Application:

>  Industry hot face special position of the thermal technology equipment;
Burner brick, observation hole, electric heating element support, riser, chute, hanging wall masonry, the roof
