 PRODUCT
CODE: SF/FB
Our customers have grown to expect only the highest quality
product from PMC A Division of R-SCC.
This construction
offers a chemical and abrasion resistant product for temperatures up
to 500°F (260°C). The primary conductors are insulated with
synthetic fibers and specially saturated and color-coded. The singles
are then laid parallel, jacketed with fiberglass and saturated overall.
The smaller sizes
with reduced diameter and easy stripablility make this product well
suited for autoclave curing processes and other bonding applications.
Other sizes shown are often used as replacement for asbestos in metal
processing, glass manufacturing or other applications where the exceptional
abrasion resistance offered by this product is mandatory.
You will find our
qualified sales and engineering staff eager to assist you in selecting
a design to meet the requirements of your specific application.

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).

Thermocouple
wire cannot be expected to meet the limits of error at temperatures
below the ice point unless specified at time of purchase. |
