Silicon carbide ceramic foam filter adopts German imported polyurethane foam sponge as the carrier, the slurry which mainly contains silicon carbide is extruded into the foam sponge, and then extrude slurry, the remaining slurry coated around the foam fiber is dring, roasting and sintering at high temperature, polyurethane is decomposed by heat, foam shaped ceramic products are left, namely, silicon carbide foam ceramic filter, simply, SIC Ceramic Foam Filter.

SIC filters production process

Sufficient production capacity can always guarantee timely delivery in Hebei Cangchen.

What the basic factors determine product quality?

However, quality always comes first no matter how large order our clients place to Hebei Cangchen and how fast production it is.

Three basic factors of quality control:

● Dimensions, such as: Length, width, thickness and diameter.

● PPI

● Compressive strength

In Hebei Cangchen, strict quality inspection and control system are well-established.

Three most important key points that make our quality always best are:

● The most advanced testing equipment and technology are adopted today in Hebei Cangchen to ensure the consistant filters quality. 

● There is a quality inspection team with rich experience and technology to keep best quality in our quality control department.

● Thanks to many years of product export and feedback information from domestic and foreign customers, we have accumulated considerable experience and expertise in quality control and improvement.

Dimensions, such as: Length, width, thickness and diameter.

PPI (pores per inch) indicates the number of cells in the foam per inch. The standard range is 10-80 PPI. PPI 10 has large cells and is completely open, while PPI 80 has small cells, is more dense, and has a lower air flow.

Compressive strength: The limit of strength when external pressure is pressed.

For now, Hebei Cangchen, a professional manufacturer with ISO certificate and our Silicon Carbide (SIC) ceramic foam filters have been certified by RoHS & Reach.

All dimensions can be customized according to clients' requirements!
