Customized Phase Change Wax N Octadecane C18 Industrial Grade is a versatile thermal management material engineered for tailored temperature control solutions.
| Quantity: | |
|---|---|
Based on high-purity n-octadecane (C18), its standard phase transition occurs at 28°C with a latent heat capacity of 245 J/g, but it can be customized to meet specific melting point requirements (25–30°C) for niche applications . This industrial-grade wax is widely used in electronics, packaging, and medical devices, where precision thermal regulation is critical.
Tailorable Phase Temperatures
Through adjustments in hydrocarbon composition, the melting point can be fine-tuned to ±1°C, ensuring compatibility with unique application needs such as electronic device cooling or constant temperature packaging.
High Energy Density
With 245 J/g latent heat, it outperforms many organic PCMs, providing longer-lasting thermal buffering in portable devices and shipping containers .
Material Compatibility
It is inert to most plastics, metals, and textiles, allowing seamless integration into existing manufacturing processes without causing corrosion or degradation.
Electronics Thermal Management
In lithium-ion battery packs and LED systems, it dissipates excess heat, maintaining operating temperatures below 40°C and extending component lifespan by 50%.
Temperature-Sensitive Packaging
Customized to 28°C, it protects pharmaceuticals and biologics during transit, ensuring stability in regions with ambient temperatures up to 35°C.
Medical Devices
Used in warming blankets and diagnostic equipment, it provides consistent heat output, enhancing patient comfort and test accuracy.

What is the latent heat capacity of C18 wax?
It delivers 245 J/g, ensuring efficient thermal storage for extended periods .
Is it suitable for high-volume industrial use?
Absolutely, its material compatibility and scalable production make it ideal for mass applications in electronics and packaging.
Minimal Impurity Interference: The content of impurities such as olefins, aromatics, sulfur and nitrogen compounds in n-octadecane is typically below 0.1%, avoiding issues like oxidation catalysis and performance fluctuations caused by impurities. For example, in the lubrication of precision instruments, low impurity levels can reduce equipment wear and sludge formation.
Highly Predictable Reactivity: When used as a synthetic raw material (e.g., in the production of octadecylamine and surfactants), its high purity ensures stable reaction conversion rates and reduces the cost of by-product separation.
Stable Phase Change Behavior: It has a large phase change latent heat, making it a core component of phase change energy storage materials (such as in building insulation and temperature control of electronic devices). Compared with low-purity products, its energy storage efficiency can be improved by 10%-15%.
Balanced Fluidity and Sealability: It is solid at room temperature (melting into a liquid when slightly above room temperature). In the liquid state, it has moderate viscosity and can be used as a sealant or a component of hot-melt adhesives, combining sealability with easy operability.
Low Volatility and High Flash Point: It has a high boiling point and a high flash point, with almost no volatility at room temperature. Its operational safety is far superior to that of short-chain alkanes, making it suitable for long-term static application scenarios (such as moisture-proof coatings in cultural relic protection).
Calibration Benchmark: It can serve as a standard for gas chromatography (GC) analysis, used for qualitative and quantitative calibration of long-chain alkanes. The stability of its retention time is far better than that of mixed alkanes.
Model Compound: In materials science, high-purity n-octadecane can simulate the basic properties of long-chain alkanes, such as crystallization kinetics and intermolecular forces, providing a theoretical basis for polymer modification and lubricating oil formulation design.
Agriculture and Environmental Protection: It can be used as a carrier for insect sex pheromones (enabling slow release) or in biodegradation research for oil-contaminated soil remediation (the pure substance facilitates tracking of degradation pathways).
