Insulation Felts
Engine Exhaust System Insulation1000° - 1500°
Lewco Sil Mat insulation is manufactured using 98% pure textilegrade silica fiber needled together into blanket/felt form. LewcoSil Mat base fiber is made through a hot extrusion processyielding 6-11micron, non-respirable fiber. This fiber is thenprocessed to maximize thermal efficiency. Lewco Sil Mat isINCOMBUSTIBLE, ASBESTOS FREE, NON-RESPIRABLE, andcontains no ORGANIC, or RESINOUS BINDERS. Typicalapplications include engine exhaust system insulation, hotindustrial equipment insulation, and many others. Maximumtemperature - 1800°F

Lewco can combine our Silica and Fiberglass insulation felts into needled compositesthat for many insulation applications can give customers the pricing advantage ofFiberglass with the high temperature properties of Silica fiber. Lewco can combinethese two different felts into various thickness combinations to meet customerrequirements. These insulation felt composites are strong enough to give long life intough, difficult applications. Applications include; Stress Relief blankets,Removable/Reusable Insulation for high noise level, high maintenance, high vibrationand high temperature equipment or engine exhaust systems.

Lewco can combine our Silica and Fiberglass insulation felts into needled compositesthat for many insulation applications can give customers the pricing advantage ofFiberglass with the high temperature properties of Silica fiber. Lewco can combinethese two different felts into various thickness combinations to meet customerrequirements. These insulation felt composites are strong enough to give long life intough, difficult applications. Applications include; Stress Relief blankets,Removable/Reusable Insulation for high noise level, high maintenance, high vibrationand high temperature equipment or engine exhaust systems.
