Phase Change Materials (PCM) gel bricks are engineered cold chain solutions for pharmaceutical, biotech, and precision temperature logistics. Unlike standard ice packs that hover around 0°C, Envirofreeze PCM gel bricks are formulated to maintain specific target temperatures — -15°C, -18°C, and -21°C — making them essential for frozen cold chain applications.
What Are PCM Gel Bricks?
PCM gel bricks are sealed rigid containers filled with a phase-change material engineered to absorb and release energy at a precise temperature point. When frozen to their target temperature and packed with your shipment, they maintain that temperature range far more consistently and for longer than standard ice or gel packs.
Applications
- Pharmaceutical cold chain — insulin, biologics, vaccines requiring frozen transport
- Biotech samples and diagnostic specimens
- Frozen food export and premium food logistics
- Laboratory specimens requiring precise temperature ranges
- Clinical trial materials and medical devices
Available in -15°C, -18°C, and -21°C formulations. Contact us on 1300 282 796 for volume pricing and technical specifications.
