PCM 20°C Phase-Change Ice Brick

PCM phase‑change ice brick is designed for constant‑temperature logistics scenarios within 15‑25℃ temperature band, for medicines and biological materials which cannot be frozen nor exposed to high heat. Its phase‑change point stays at 20℃. When surrounding temperature goes higher, it absorbs heat; when temperature drops too low, it releases stored heat. This bidirectional buffering effect mitigates dramatic temperature swings inside thermal packaging.

The outer casing uses high‑strength leak‑proof material, adapting to complex pallet‑logistics handling conditions. We supply standard‑size PCM ice bricks, and support custom‑made dimension to fit inner space of pallet thermal covers or large‑volume insulation boxes. Custom printed labels including technical parameters and client brand logo can be offered for mass orders.

Each production batch carries out sampling test of phase‑change performance to guarantee consistent product quality. This PCM ice brick is mostly used together with our series pallet thermal covers for large‑batch cargo temperature protection on pallets. Main customers cover pharmaceutical logistics companies and biotech product distributors. It solves the pain point that some medical products are damaged by either high temperature or freezing. As bidirectional temperature‑buffering PCM consumable, it complements low‑temperature PCM‑20℃and mid‑cold PCM5℃, enriching our full‑range passive cold‑chain material portfolio.
