COPTON Low conductivity
Specially developed for electric vehicle battery and motor cooling systems, it utilizes advanced non-ionic additives and is formulated with polyester-grade ethylene glycol and low-conductivity deionized water as raw materials. It exhibits outstanding insulation, corrosion-resistant heat dissipation, and material compatibility, comprehensively ensuring the safe and stable operation of the cooling system.
1.Specially formulated for the cooling systems of EV batteries and motors, featuring superior thermal management and safety performance.
2.Ultra-low electrical conductivity (<100 μS/cm) effectively eliminates risks of internal short circuits and electric leakage caused by coolant leakage, delivering reliable safety protection for high-voltage systems.
3.Contains macromolecular chelating agents and water hardness stabilizers to prevent sediment formation and battery overheating resulting from pipeline blockages.
4.Boasts excellent anti-corrosion performance, providing long-term corrosion protection for cooling plates, pipelines, heat exchangers, water pumps and other components.
5.Offers outstanding seal compatibility, preventing deformation, cracking and other defects of non-metallic parts such as plastics and rubbers during service.
Applicable to electric vehicle cooling systems that utilize liquid cooling as the heat dissipation method for power battery packs and motors.
