PTC thermal insulation gasket for new energy vehicles

PTC thermal insulation gasket for new energy vehicles

New energy vehicle PTC thermal insulation gasket is an ultra-thin, high thermal conductivity and high insulation thermal interface material specially designed for vehicle PTC heaters (warm air/battery preheating). Its core function is to realize high-efficiency heat transfer and high-voltage electrical isolation between PTC ceramic heating element and aluminum radiator at the same time, so as to ensure heating efficiency and electrical safety of the whole vehicle.
Product Features

Heat conduction: fill the micro gap between the PTC chip and the heat dissipation fin, reduce the contact thermal resistance, quickly export the heat, improve the heating efficiency, and prevent the PTC from overheating and aging.

Insulation: reliable electrical isolation is formed between the high-voltage charged PTC electrode and the grounded metal radiator to prevent short circuit, leakage and breakdown, and meet the safety standards of vehicle gauge level.

Buffer: compensation for thermal expansion and contraction differences, anti-vibration, anti-tearing, to ensure long-term reliability
