SILICA CLOTH TYPES SIL-1, SIL-2 & SIL-3 ZIRCAR Refractory Composites, Inc. produces a comprehensive range of advanced high performance ceramic-ceramic composites and related products. Our materials are used around the world in demanding thermal, structural and electrical insulating applications at temperatures from 600°C(1112°F) to 1650°C(3002°F). For over twenty-five years we have been a problem solver working with many industries to resolve their thermal management problems. We have developed materials that have become industry standards for induction melting, forging and heat-treating applications, investment casting, glass processing, hot pressing, as well as many high temperature electrical applications. GENERAL INFORMATION ZIRCAR Type SIL Silica Cloths consists of a useful variety of amorphous silica fiber fabrics. These fabrics are manufactured from glass fiber textiles which are acid leached. These silica textiles are strong and easy to work with. They exhibit good handleability and remain flexible in numerous high temperature applications. Type SIL cloths are useful where non-RCF textiles are desired. Type SIL Silica Cloths meet Mil Spec MII-C24576 type 1, Class 2.
