Cold Chain Phase Change Wax N Hexadecane C16 Industrial Grade is a specialized phase change material (PCM) designed for thermal energy storage in temperature-sensitive logistics.
| Quantity: | |
|---|---|
Composed of high-purity n-hexadecane (C16), it undergoes phase transition at 18°C with an impressive latent heat of 237 J/g, enabling efficient absorption and release of thermal energy to maintain stable temperatures . This industrial-grade wax is engineered for reliability in cold chain applications, where consistent temperature control between 2–8°C is critical for pharmaceuticals, fresh produce, and biotech products.
Precise Phase Transition Temperature
With a melting point of 18°C, it acts as a thermal buffer, preventing temperature spikes above 20°C during transit. This precision outperforms broader-range PCMs, which may fail to maintain narrow temperature windows .
High Latent Heat Capacity
Its 237 J/g latent heat allows it to store significant thermal energy per unit mass, reducing the number of PCM packs required for cargo. This translates to 30% lower packaging weight compared to conventional coolants .
Thermal Cycle Stability
Tested to withstand 500+ thermal cycles without degradation, it retains over 95% of its latent heat capacity, ensuring long-term performance in repeated use scenarios .
Pharmaceutical Logistics
Used in insulated shippers for vaccines and biologics, it maintains 2–8°C temperatures for 72+ hours during transit, complying with WHO cold chain standards.
Fresh Food Preservation
In seafood and produce containers, it mitigates temperature fluctuations caused by ambient heat, extending shelf life by 3–5 days compared to non-PCM packaging.
Portable Cooling Systems
Integrated into reusable cold packs for medical kits and camping gear, its reversible phase change provides consistent cooling without electricity.
What is the phase transition temperature of C16 wax?
It melts at 18°C, making it ideal for maintaining sub-20°C environments critical for temperature-sensitive goods .
How long does it retain thermal stability?
It sustains over 500 thermal cycles with minimal performance loss, ensuring reliability in multi-use cold chain operations .
Is it compatible with food-contact materials?
Yes, its high-purity n-hexadecane composition meets FDA standards for indirect food contact, suitable for fresh produce packaging .
