Welcome to PMC Corporation

PRODUCT CODE: TA/TA

Our customers have grown to expect only the highest quality product form PMC A Division of R-SCC. We are continuously committed to meet the specific needs of industry and our customers. This construction includes PFA insulation extruded on the single conductors which are then laid parallel and jacketed with a PFA.

PFA (perfluoroalkoxy) was released in 1972 by E.I. Dupont Inc. It possesses similar properties of the other PFA products such as outstanding electrical characteristics, resistance to virtually all chemicals and excellent flame resistance.

PFA is a true thermoplastic material extrudable by conventional means, and available in long continuous lengths. This construction provides flexibility and toughness with a stress crack resistance, resistance to weather, non-again characteristics, and low coefficient of friction for ease of pulling through conduit.

Like TFE, suggested upper continuous temperature is 500°F (260°C), however, it does not have TFE's solder iron resistance.

The thermocouple grade products shown are used to form temperature sensors and the extension grade products become the interconnecting link in the temperature sensing system.

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 aluminum polyester tape to reduce noise problems found in so many of today's plants.

Typical applications include aircraft an automotive engine testing, rapid transit cables, and down hole cable in the oil industry.

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.
