Description
DM-80 Thermal conductive silicone film is an advanced fabric-reinforced thermal interface material designed for efficient heat dissipation, electrical insulation, and reliable mechanical assembly in modern electronic systems. Built on a composite structure of silicone elastomer and glass fiber reinforcement, it delivers a balanced combination of thermal transfer capability, dielectric strength, mechanical durability, and installation convenience. This makes it suitable for a wide range of heat-generating electronic and electrical equipment where stable thermal control is essential.
Unlike conventional soft thermal pads, this thermal conductive silicone film uses a specially engineered fabric-like structure to enhance dimensional stability while maintaining excellent conformability. The reinforcement layer significantly improves handling performance during assembly, allowing consistent placement even in large-scale manufacturing environments. At the same time, the silicone matrix ensures effective contact with uneven surfaces, reducing air gaps and improving overall thermal efficiency.
Product Structure and Material Composition
DM-80 thermal conductive silicone film is constructed using a high-performance silicone base combined with glass fiber reinforcement through a specialized lamination process. This hybrid structure provides both flexibility and mechanical strength, ensuring stable performance under compression and long-term operational conditions.
The silicone component provides inherent thermal conductivity, electrical insulation, and resistance to environmental stress. The glass fiber layer enhances tensile strength and dimensional stability, preventing deformation during installation or thermal cycling. This combination ensures that the material maintains consistent thickness and thermal performance even in demanding applications.
Thermal and Electrical Performance Characteristics
One of the key advantages of DM-80 thermal conductive silicone film is its optimized thermal resistance performance, measured at approximately 0.41°C·in²/W (@ 50 psi). This low thermal resistance enables efficient heat transfer between electronic components and heat dissipation structures, improving overall system thermal management.
The material also offers high dielectric strength, with withstand voltage capability up to 6000V, making it suitable for applications where electrical isolation is required between heat-generating components and conductive surfaces. This dual functionality of thermal conduction and electrical insulation allows engineers to simplify system design while maintaining safety and reliability.
In addition, the material is designed with flame-retardant properties compliant with UL-94 V-0 rating, ensuring safe operation in environments where fire resistance is critical.
Mechanical Properties and Stability
DM-80 thermal conductive silicone film is engineered to maintain structural integrity under mechanical stress and compression. With a hardness rating of Shore C 70±5, it offers a balanced combination of softness for surface conformity and stiffness for structural stability.
The tensile strength exceeds 180 kg/cm², ensuring durability during handling, cutting, and assembly processes. Its elongation rate of 3–8% provides controlled flexibility without compromising dimensional accuracy. The low deformation characteristics make it particularly suitable for precision electronic assemblies where consistent thickness and positioning are required.
The material also maintains stable performance across a wide temperature range of -50°C to +200°C, ensuring reliable operation in both low-temperature environments and high-heat electronic systems.
Thermal Conductivity and Heat Dissipation Efficiency
With a thermal conductivity of 1.0 W/(m·K), DM-80 thermal conductive silicone film efficiently transfers heat away from electronic components such as power modules, processors, and automotive control units. The reinforced structure ensures uniform heat distribution across the surface, reducing localized hotspots and improving overall thermal stability.
By filling microscopic air gaps between heat sources and cooling interfaces, the material significantly reduces interfacial thermal resistance. This improves heat transfer efficiency without requiring additional mechanical modifications to system architecture. The result is enhanced performance stability and extended service life for heat-sensitive electronic components.
