PCM 5°C Phase-Change Ice Brick

PCM 5℃ phase‑change ice brick is our core temperature‑locking consumable for classic 2‑8℃ medical cold‑chain logistics, which is the most common temperature requirement for vaccines, biological reagents, insulin and many prescription biologic drugs. Its phase‑change point is precisely tuned at 5℃. When ambient temperature rises, PCM material absorbs massive heat in phase‑change process, slowing temperature rise inside closed cold‑chain container and keeping medicine within safe 2‑8℃ range for a long time.

The outer shell adopts high‑strength leak‑proof sealed housing to avoid liquid leakage even under extrusion in transit. We provide standard sizes, and can tailor‑make outer dimension, thickness and weight according to customers’ cold‑box inner cavity structure, so ice bricks can fit boxes perfectly without wasting inner space. Custom‑printed labels with specification, warning marks or client brand logo are available for bulk orders.

Every production batch is sampled and tested for phase‑change temperature accuracy to guarantee performance consistency. This PCM5 ice brick works seamlessly with our PPVIP, PUVIP, XPS series medication cold chain boxes. Clients can calculate required quantity of ice bricks according to target holding‑time and box volume. It is heavily adopted by pharmaceutical distributors, biotech companies and cold‑packaging solution providers. As fundamental component of passive cold‑chain solution, reliable PCM5 ice brick is critical to guarantee end‑to‑end medicine transportation safety.
