High Temperature Insulation Solutions

A one-source solution for thermal products and custom fabrication for a wide range of industries and applications.


An Alternative to Silica Fiber Fabric - FLEXIBLE AND STRONG EVEN AT 1500F / 815C

ISOTEX® 1500 Fabrics from McAllister Mills are made from continuous filament, shot-free fibers with excellent chemical and heat resistance.  As a standard practice, our fabrics are heat treated to remove the majority of the finish from the original yarns, providing a low smoke product when brought to service temperature.  Heat resistant to 1500F / 815C continuous due to its fiber chemistry, ISOTEX® fabrics are 25% stronger than traditional e-glass fabrics and have up to a 30% lower thermal conductivity.  ISOTEX® delivers, adding flexibility when temperatures exceed 1000F / 550C.  ISOTEX® is an excellent choice when considering Silica Fiber materials but when the service temperatures are 1500F / 815C or below.
