KAPTON INSULATED WIRE

Kapton - KK

Kapton polyimide film is applied to both the positive and negative conductor or just to the positive conductor. Kapton is highly resistive to abrasion, radiation and is non-flammable. Excellent for use in extremely harsh environments. No ISA/ ASTM color code. Kapton has no known organic solvents. Kapton is an excellent choice for cryogenic environments because its insulating characteristics remain intact at lower temperatures. Offered in thermocouple grade. Temperature rating: Continuous: Up to 550°F (285°C). Intermittent: Up to 750°F (400°C).

NYLON INSULATED WIRE

Nylon-Nylon - NN

Color-coded nylon is extruded on both positive and negative conductors with a nylon outer jacket. This insulation has excellent abrasion resistance, excellent chemical resistance, and poor moisture resistance. Offered in thermocouple grade. Temperature rating: Continuous: Up to 350°F and 177°C.

TEFLON INSULATED WIRE

Teflon (extruded) Teflon (extruded) - TT

Color-coded Teflon (FEP)* is extruded on the positive and negative conductors and outer jacket. This insulation is unaffected by most corrosive substances, outdoor weather, or lubricants. It is flame resistant and heat aging will not cause embrittlement or cracking. Good for cryogenic applications. Offered in thermocouple grade. Temperature rating: Continuous: Up to 400°F (200°C).

Teflon (Fused TFE Tape) Teflon (Fused TFE Tape) - TF

TFE tape is spirally applied to the conductor and heated. This process fuses the tape into a homogeneous layer of TFE. Fused teflon wire offers good abrasion resistance and excellent resistance to both moisture and chemicals. Offered in thermocouple grade. Temperature rating: Continuous: Up to 500°F (260°C).

FIBROUS INSULATED WIRE

Fiberglass Braid - GG

Glass braid on individual conductors with glass braid outer jacket. Designed for continuous use in high temperature applications. Poor abrasion and moisture resistance. Offered in thermocouple grade. Temperature rating: Continuous: Up to 900°F (482°C). Intermittent: Up to 1000°F (529°C).

Hightemp Fiberglass Braid - HG

A high temperature fiberglass braid is applied over each conductor and then impregnated with a binder. Although the binder improves resistance to abrasion and moisture, it is destroyed above 400°F (204°C). Offered in thermocouple grade. Temperature rating: Continuous: Up to 1300°F (705°C). Intermittent: Up to 1600°F (871°C). We recommend SS overbraid with this wire (Ordering Code HS).

Fiberglass and Hightemp Fiberglass Braid with Stainless Steel Overbraid - GS and HS

A stainless steel overbraid is applied to fiberglass (Ordering Code GS) or high temperature fiberglass (Ordering Code HS) wire insulation to increase the wire’s resistance to abrasion, mechanical and physical damage. It may be applied to 14 through 30 gauge conductors. Other overbraid materials such as Inconel* are also available by special order codes.

Refrasil - RR

Vitreous silica is applied on both positive and negative conductors with a vitreous silica outer jacket. Refrasil is typically not color coded. Used in high temperature applications, including furnace, load thermocouple and traveling thermocouple applications. Moisture and abrasion resistance only fair. Offered in thermocouple grade. Available with SAE AMS 2750 compliant calibration data. Temperature rating: Continuous: Up to 1600°F (871°C). Intermittent: Up to 1800°F (982°C). We recommend stainless steel or other overbraid with this wire.

Nextel - NE

A high temperature ceramic fiber is applied over each conductor and then overall. Nextel is not colored coded. Although nextel is not recommended for use with platinum thermocouples, it can be used as an excellent option for other high temperature applications. Its use is limited by the temperature rating of the thermocouple wire it insulates. It is frequently used in furnace and traveling thermocouple applications. Available with SAE AMS 2750 compliant calibration data. Temperature rating: Continuous: Up to 2200°F (1200°C). We recommend SS overbraid with this wire.
