WIRE INSULATION MATERIAL
POLYVINYL CHLORIDE INSULATED WIRE
Polyvinyl Chloride-Polyvinyl Chlorid-PP
Color coded polyvinyl chloride is extruded on each individual conductor and on the outer jacket. It has dielectric and mechanical strength, plus flexibility. PVC is resistant to flame, moisture and pulled through a conduit. lt is offered in thermocouple extension grade. Temperature rating: Continuous: -20 to +221°F G29 to 105°C)
Polyvinyl Chloride Rip-Cord Construction-PC
Polyvinyl chloride is extruded on both positive and negative conductors imultaneously to form a rip-cord construction. Offered in thermocouple grade 24 gauge solid conductors. Temperature rating: 29 to +105°C
Polyvlnyl Chlorlde wlth Twlsted Conductors, Aluminum Mylar' Shield, and Drain Wlre-P
Polyvinyl chloride insulates the positive and negative conductors. The conductors are then twisted and helically > wrapped with an aluminum backed Mylar* type. A bare copper drain wire runs through the construction in contact with gthe aluminum tape furnishing a low resistance path lo ground. The twisted shield provides electrostatic interference reiection. The outer jacket is of polyvinyl chloride which has excellent mechanical strength. Wire is resistanto flame, mbisture, and abrasi6n. Offered in 6xtension grade. Thermocouple grade available upon-request. Temperature nating: @ Continuous: Up to 176°F and 80°C

KAPTON INSULATED WIRE
Kapton polyimide film is applied to both the positive and negative conductor or iust to the positive conductor. Kapton - is highiy resistiire to abrasion, iadiation and is non-flammable.- Excellent for use i'n extremeiy harsh environment.. ruo @ ISA color code. Kapton has no known organic because its insulating characteristics remain intact at lower temperatures. Offered in rating: Continuous: Up to 550'and 285'C. Intermittent: Up to 400°C or 750°F
NYLON INSULATED WIRE
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. Excellent for cryogenic applications. Offered in thermocouple grade. Temperature rating: Continuous: Up to 400°F and 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 and 260°C.
FIBROUS INSULATED WIRE
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 and 482°C. Intermittent: Up to 1000°F and 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 and 705°C. Intermittent: Up to 1600°F and 871°C.
We recommend SS overbraid with this wire.
Fiberglass Braid with Stainless Steel Overbraid-GS and HS
A stainless steel overbraid is applied to fiberglass wire to increase the wires resistance to abrasion, mechanical
and physical damage. It may be applied to 14 through 30 gauge conductors.
Vitreous silica is applied on both positive and negative conductors with a vitreous silica outer jacket. Refrasil is
not color coded. Used in high temperature applications. Moisture and abrasion resistance only fair. Offered in thermocouple grade. Temperature rating: Continuous: Up to 1600°F and 871°C. Intermittent: Up to 1800°F and 982°C. We
recommend SS overbraid with this wire.
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. Temperature rating: Continuous: Up to 2200°F.
