Sialtex®

Sialtex® is a new line of products manufactured with 7 micron diameter and boron-free Silica Allumina yarns. The diameter of 7 microns allows greater flexibility to the materials when compared with others available on the market and the absence of boron means that there are no problems related to the use in the presence of release of boron gas. The main composition of Sialtex® products is 72% alumina and 28% silica or 80% alumina and 20% silica; however, there are also compositions with different formulations.
There is almost no reduction in the mechanical strength of Sialtex® textile products at temperatures up to 1200 ° C and they can be used for applications with temperatures close to 1395°C.
