E Needled Fiberglass

We use Lewco Mat High Temperature Needled Insulation Felts

Lewco Sil Mat insulation – 98% Silica Fiber to 1800F

Lewco Sil Mat insulation is manufactured using 98% pure textile grade silica fiber needled together into blanket/felt form. Lewco Sil Mat base fiber is made through a hot extrusion process yielding 6-11micron, non-respirable fiber. This fiber is then processed to maximize thermal efficiency. Lewco Sil Mat is INCOMBUSTIBLE, ASBESTOS FREE, NONRESPIRABLE, and contains no ORGANIC, or RESINOUS BINDERS. Typical applications include engine exhaust system insulation, hot industrial equipment insulation, and many others. Maximum temperature – 1800°F

Fiberglass – 100% E Glass Fiber to 1200F

Lewco Glass Mat is composed of 100% select-grade type “E” glass fibers needled together into mat form. It is INCOMBUSTIBLE, ASBESTOS FREE, and contains NO RESINOUS OR INORGANIC BINDERS. Lewco Glass Mat can be used on equipment operating at temperatures to 1200°F and will not deteriorate or shake apart in vibrating applications. Comforms to Mil. Spec. Mil-I-16411, Mil-I- 24244, ASTM E-84. Smoke -O, Flame -O NRC-1.36
