Duplex PEEK Insulated Thermocouple Wire

We provide flat duplex insulated thermocouple wire consisting of a pair of conductors individually PEEK-resin insulated, and then PEEK-resin sheathed. PEEK resin is an insulating material that exhibits excellent properties, including no halogen content, low outgassing, a high melting point, and a high radiation resistance.

Product Features

Features of PEEK resin
No halogen content, low outgassing
low elution, low toxic-gas content
High heat resistance (260℃), high melting point (340℃) *The heat distortion temperature is 1.5 times higher than that of PTEF.
flame resistance (UL94-V0 certified without adding a flame retardant)
radiation resistance, and high sliding performance
Lineup
In response to the needs of many of our customers, we provide Types K and T, with 0.32-mm and 0.65-mm conductors, respectively. We can also make products compliant with Class 1. Please specify when placing an order.
