Welcome to PMC Corporation

PRODUCT CODE: RB/RB

Our customers have grown to expect only the highest quality products from PMC A Division of R-SCC. Filaflex® was developed to operate in applications to withstand continuous temperatures as high as 1400°F (760°C) without flexing or abrasion. Filaflex is being used in applications to replace asbestos, or where standard fiberglass won’t stand up.

Filaflex designs contain single conductors insulated with a high tensile strength low alkali magnesia alumina silicate vitreous fiber braid. Prior to impregnation the insulation is inorganic, incombustible and will neither expand nor contract with moisture changes. Once the material has been braided onto the wire, it is impregnated with a special binder to improve moisture and abrasion resistance. The singles are then laid parallel and a braided jacket of the same material is
applied and impregnated.

Many customers use this product as singles twisted together with no jacket for expandable thermocouple applications. See Data sheet #146 for information. 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 are available upon request, including protective metal coverings for improved abrasion resistance.

NOTE:	Percent limits apply directly to temperature in °C units, but for °F equivalents are applied to the numbers of °F above or below the ice point (+32°F). (i.e. Limit (°F) = (Temp. °F-32°F) x Percentage)
	Thermocouple wire cannot be expected to meet the limits of error at temperatures below the ice point unless specified at time of purchase.
