 PRODUCT
CODE: FW2/FB
Our customers have grown to expect only the highest quality products
fromPMC A Division of R-SCC. This construction consisits of fiberglass
yarns wrapped in a two pass configuration, then impregnated with special
resistance. The singles are then laid parallel and a braided jacket
is applied and impregnated.
While wire gaure
size, calibration and atmosphere will affect maximum useful temperature
in applications, this insulation is designed to withstand a maximum
continuous use at 900° F (482°C) and a single exposure use at
1000°F(537°C). (Note: Impregnations retained to 400°F (204°C)
).
You will find our
qualified sales and engineering staff eager to assist in selecting a
design to meet the requirements of your specific application. Variations
of this construction including protective metal coverings for improved
abrasion resistance are available upon request.
Typical applications
include aerospace, aluminum mill, foundries, ovens, furnaces, heat treating,
plastics industry, senesor leads as well as others.
