Product Name:UL-2931
Rated temperature: 105°C
Rated voltage: 125V
Function:
1. Internal connections in high-temperature electrical appliances
Coffee machine/electric kettle heating module:
A certain international small appliance brand uses UL2931 to replace ordinary 80°C wire to solve the problem of insulation ageing in the 105°C high-temperature environment around the heating element.
Oven control board wiring:
Passes 125V pressure test, used for temperature control system connection wires in ovens from brands such as Midea.
2. Precision electronic equipment
Medical Disinfection Equipment:
Internal wiring harness for steam sterilizers, passing:
105°C saturated steam environment testing (50 cycles per week)
Medical disinfectant compatibility verification
Industrial Sensors:
Sensors for high-temperature workshops (80°C environment), addressing:
Signal interference issues (tin-plated copper conductors reduce impedance)
Fractures caused by frequent vibrations (twisted conductor structure)
3. Special applications for microdevices
TWS earphone charging case:
40AWG ultra-fine wire diameter for compact spaces,
48-hour salt spray test (tin-plated copper for oxidation resistance)
Material:
Conductors use single or stranded minimum 40AWG tinned or bare copper
SR-PVC/PVC insulation,
PVC sheath,
compliant with ROHS 2.0 environmental standards and Reach standards
uses standard insulation thickness, easy to cut and strip
Standards:
Reference Standards: UL758, UL1581
Conductors use single or stranded minimum 40AWG tinned or bare copper
SR-PVC/PVC insulation,
PVC sheath,
Compliant with ROHS 2.0 environmental standards and REACH standards
Passed UL VW-1 and JQA F-Mark flame retardant tests
Core Advantages:
1. High-temperature resistance (long-term stable operation at 105°C)
High-temperature performance:
Utilises SR-PVC/PVC composite insulation, enabling long-term operation at 105°C, offering superior heat resistance compared to standard PVC cables (80°C). Ideal for heating zones in small appliances and industrial high-temperature environments.
Passes UL1581 high-temperature ageing test (300 hours without cracking), ensuring long-term reliability.
125V voltage rating design:
Suitable for low-voltage systems such as home appliances, medical equipment, and automotive electronics, meeting safety redundancy requirements.
2. Ultra-fine conductor (40AWG, ideal for miniature devices)
Ultra-fine wire diameter (40AWG):
Conductor cross-sectional area of only 0.031mm², suitable for space-constrained applications such as TWS earbuds, miniature sensors, and medical catheters.
Single or stranded conductor options available, with stranded structure offering greater flexibility.
Tin-plated copper for oxidation resistance:
The tin coating effectively prevents oxidation of the copper conductor, extending service life (48-hour salt spray test with no corrosion).
3. Comprehensive safety certifications
International certification compliance:
UL VW-1 flame retardant: Vertical burning test self-extinguishing time ≤3 seconds, reducing fire risk.
JQA F-Mark: Complies with Japanese market safety standards.
RoHS 2.0 & REACH: Free of lead, cadmium, and other harmful substances, ensuring compliance for exports to Europe and the Americas.
