Product Description

Awg 20 High Temperature Resistance Silicon Rubber Cable For Heating Mat With Self-regulating Heating Cable

Insulation material: Silicon Rubber

Long-term max standing temperature	300ºC
Shor-term max standingtemperature	350ºC

 

Conductor: Ni80Cr20/ Ni60Cr15

Ni80Cr20 is a nickel-chromium alloy (NiCr alloy) characterized by high resistivity, good oxidation resistance and very good form stability. It is suitable for use at temperatures up to 1200°C,and hold a superior service life compared to Iron chromium alumium alloys.

Typical applications for Ni80Cr20 are electric heating elements in home appliances,industrial furnaces and resistors(wirewound resistors,metal film resistors), flat irons, ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements and cartridge elements.
