GTP-PCM180-LH PCM Heat Absorbing Materials
GTP-PCM180-LH is a non-silicon phase change material with an organic cross-linked network structure, offering high latent heat (≥180 J/g), excellent stability, insulation, and thermal conductivity. It absorbs heat at a design temperature of 37 or 43°C, providing efficient thermal management for temperature-sensitive and high-power devices by delaying temperature rise.
The material has high mechanical strength and flexibility after heat absorption, ensuring interface compatibility and effective heat transfer. It can be processed into sheets of varying thickness or molded into custom shapes for various applications.
