Ceramic Filter Sponge or Open Cell Reticulated Polyurethane Foam Sponge Rew Material for Ceramic Filter Sponge

We produce raw material of the Ceramic Filter sponges, the Reticulated (open cell) PU sponges. You can customize the porosity, color, size, and shape of the products as your need.

Ceramic Filter sponges are developed as a new type filter for molten metal, can stop and filter foreign matter to decrease casting flaw. They are widely used for aluminum, copper, iron and steel casting applications.

Ceramic Filter Sponges can be used in casting purifying, gas-solid mixture separation and liquid-solid mixture separation, and can also works as catalyst support, burner and silencer materials.

Ceramic Filter Sponges have the characters of light weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, chemical corrosion resistance and high temperature stability in molten metal.

Features:

1.     Decontaminate the melting metal liquid.

2.     Simplified gating system.

3.     Improve the metallurgical structure of the castings.

4.     Reduce impurities of the castings.

5.     Improve casting quality rate.

6.     Reduce casting internal re-oxidation defects.

7.     Reduce the surface defects after machining of the castings.
