Key Properties
Introduction
Paraffin wax based PCMs also called 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 thermal storage materials composed primarily of linear alkane chains with controlled carbon distributions. These materials provide tunable phase change temperature ranges across a wide spectrum of thermal management applications.
Paraffin wax PCMs are characterized by excellent chemical inertness, low vapor pressure, negligible supercooling behavior, and reliable thermal cycling performance. Depending on the carbon chain composition and purification level, they can be engineered for applications ranging from wearable cooling and cold chain logistics to building thermal regulation and energy storage systems.
At RU Entropy, our paraffin wax PCM solutions are available in multiple formats including bulk PCM materials, gel composites, encapsulated systems, and application-specific thermal modules designed for industrial and commercial use.
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.

Typical Applications
Thermal Performance Behavior
Normal paraffin based PCMs exhibit stable phase transitions within a narrow temperature range, enabling predictable heat absorption and release. Their thermal response remains consistent under steady operating conditions.
Cycling Stability & Performance Control
With proper encapsulation, normal paraffin based PCMs demonstrate excellent cycling stability and minimal performance degradation over repeated thermal cycles. Performance control is primarily managed through material selection and containment design.
Design & Integration Considerations
Normal paraffin based PCMs can be integrated into macro-encapsulation, micro-encapsulation, and sealed thermal storage modules. Design focus typically includes heat transfer efficiency, leakage prevention, and phase change temperature matching.
