1. Product Introduction
This series of paraffin-based phase change materials (PCM) are hydrocarbon mixtures refined and processed from petroleum fractions. They are specially designed for thermal energy storage and temperature regulation applications, with high latent heat of fusion and well-defined phase change temperatures. By absorbing or releasing large amounts of heat during solid-liquid phase transition within a specific temperature range, these materials effectively store and controllably release thermal energy, helping users achieve precise temperature management in various systems.
2. Key Applications
Our paraffin PCM wax is widely used in multiple industrial and commercial fields, including:
Military & Aerospace: Thermal control for electronic components and equipment
Building & Construction: Thermal insulation and energy-saving in buildings
Thermal Energy Storage: Solar energy systems and renewable energy storage
Textile Industry: Temperature-regulating and thermal insulation fabrics
Agriculture: Greenhouse temperature control and crop protection
Electronic Cooling: Thermal management for batteries and sensitive electronics
3. Product Features & Performance
High Latent Heat: ≥120 J/g, ensuring efficient thermal energy storage
Stable Phase Change Temperature: Available in grades with melting points ranging from 17.5℃ to 37.5℃
High Normal Paraffin Content: ≥90%, ensuring consistent and reliable performance
Non-toxic & Non-corrosive: Safe for use in various environments
Low Supercooling: Maintains stable phase change behavior
Long Cycle Life: Stable performance over thousands of phase change cycles
Low Moisture Content: No trace moisture, ensuring product stability
