Flexible PTC & PI Heating Film Products Meet Rising Thermal‑Control Demands of Global New‑Energy Industry

The fast‑growing new‑energy sector puts forward strict requirements for lightweight, uniform‑temperature and compact heating components for battery pre‑heating, cabinet constant‑temperature maintenance and power‑module thermal compensation.

Silicone heating sheets feature high flexibility and tear resistance, widely applied for surface constant‑temperature heating of energy‑storage cabinets. Epoxy‑resin heating sheets provide superior insulation performance for sealed power units. Serial PTC‑based products contain flexible PTC heating sheets, aluminum‑alloy PTC ceramic heating plates and air‑conditioner PTC heaters, leveraging intrinsic positive‑temperature‑coefficient characteristics to realize passive over‑heat protection without extra complex control hardware.

PI metal heating films represent high‑end precision heating solutions, marked by ultra‑thin structure, fast thermal response and even heat distribution. Customizable dimensions enable attachment on irregular battery‑pack shells to mitigate capacity attenuation of lithium‑ion energy‑storage systems operating under sub‑zero environments. Multiple PTC heating‑film variants with adjustable power density support layered layout on battery trays and power electronics equipment. All heating elements adopt eco‑friendly conductive polymer materials, helping new‑energy equipment manufacturers reduce assembly cost while complying with international component certification requirements.
