PCM -20°C Phase-Change Ice Brick

PCM‑20 phase‑change ice brick is developed for special medical cargo that needs stable‑20℃ low‑temperature storage and transport, such as specific biological samples, laboratory specimens and special‑class biologic preparations. Its phase‑change point is precisely‑20℃. After full pre‑freezing, it absorbs external heat steadily in phase‑change process, slowing temperature climbing inside insulated packaging and maintaining required deep‑cold environment.

Special low‑temperature‑resistant sealing shell material is selected. It will not turn brittle or crack under long‑time sub‑zero condition, effectively preventing content leakage. Standard specifications are in stock; meanwhile we can adjust ice brick size, thickness and weight to match customers’ custom cold‑box inner space. Custom label printing with product parameters or client brand information is acceptable for large‑volume orders.

Each production batch will take sample test to verify actual phase‑change point performance to avoid deviation. PCM‑20 ice brick needs to be pre‑frozen under corresponding low‑temperature condition before usage. It is mainly served for biotech laboratories, scientific research institutions and special‑biomedicine trading enterprises. Remind that this product matches insulation containers suitable for deep‑cold logistics. Combined with qualified cold boxes, it constitutes complete passive low‑temperature cold‑chain solution for special medical goods transport.
