Cerapor® LDNG filter key facts

One of our products for aluminium foundry is the ceramic foam filter Cerapor® LDNG.

Special characteristics

Very good floating properties: When the runner-gating system is re-melted, the filter floats on the melt’s surface and can be skimmed together with the dross
Non-hygroscopic: Cerapor® LDNG filters are not hygroscopic
Graphite-free: Our filters do not contain any graphite
High quality: Like all of our products, our filters comply with our high quality standards.
