In today’s world, where temperature-sensitive products like vaccines, medicines, and fresh food require precise temperature control, Phase Change Material (PCM) has become the new standard for reliable cold chain performance.

Unlike traditional ice or gel packs, PCM absorbs and releases thermal energy at specific temperatures — ensuring stable, predictable cooling without the risk of freezing or overheating. This makes it the ideal solution for pharmaceutical transport boxes, vaccine carriers, and food delivery containers.

Our PCM technology is designed for long-lasting temperature stability, supporting ranges such as 2–8°C, -18°C, -25°C，or other requirements. It can maintain critical temperatures for hours — even in extreme outdoor conditions — while being eco-friendly, reusable, and leak-proof.

When used in our medical and food-grade cold boxes, PCM helps reduce energy consumption, extend cooling duration, and safeguard sensitive cargo from temperature fluctuations. It’s the smart choice for sustainable and efficient cold chain logistics.
At International Haotian Technology Co., Ltd.  we specialize in developing innovative cold storage solutions integrating PCM technology. Whether you’re transporting vaccines, biological samples, or fresh produce, we help you ensure safety, compliance, and freshness every step of the way.
