Tylose for extrusion of ceramic honeycomb

Tylose is an indispensable additive for the plastification of ceramic extrusion mixes, especially for the extrusion of technical ceramics, used in the automotive and chemical industry. Typical examples are honeycomb catalyst substrates and particle filters for exhaust gas after-treatment applications. Tylose shows fast hydration and swelling and unfolds its plastification and water retention effects in a highly efficient way. With the combination of high thermal stability, high green strength and low fibre content, Tylose enables high extrusion rates, even with ultra-thin wall substrates. In the drying process Tylose prevents cracks via its binding effect, additionally supported by its thermal gelation capabilities.
