Normal Paraffin Based PCMs
Reliable organic PCMs for Thermal Storage
Introduction
- Normal paraffin based PCMs are a class of organic phase change materials widely used for thermal energy storage and temperature regulation.
Due to their stable chemical structure, predictable phase change temperatures, and non-corrosive properties, normal paraffin PCMs are ideal for applications requiring long-term reliability and consistent thermal performance.
At RU Entropy, our normal paraffin based PCMs are engineered to deliver precise melting and solidification behavior, making them suitable for industrial, commercial, and energy-efficient systems.
Material Overview
- Normal paraffin based PCMs are hydrocarbon-based materials composed of linear alkanes with well-defined molecular structures.
- Due to their stable chemical structure, predictable phase change temperatures, and non-corrosive properties, normal paraffin PCMs are ideal for applications requiring long-term reliability and consistent thermal performance.
- During phase transition, these materials absorb or release large amounts of latent heat at nearly constant temperatures, enabling efficient thermal energy storage without significant temperature fluctuation.
- At RU Entropy, our normal paraffin based PCMs are engineered to deliver precise melting and solidification behavior, making them suitable for industrial, commercial, and energy-efficient systems.
