- UL94 V-0
Fitted Thermal Insulator
Insulation that contributes to improved thermal management efficiency, condensation prevention, higher productivity, and assembly accuracy
Intended Use
All applications requiring high performance and high safety
- Water cooling parts for data centers and AI servers
- Cooling components for 5G/6G communication equipment and power conditioners for solar cells
- Engine oil separators for agricultural machinery
- Ducts for air conditioning, etc.
Thermal Insulating ducts
Ventilation cover that contributes to lower component temperatures by maximizing the cooling effect of convection
Sample application 1
Thin-walled, complex-shaped insulation materials
SunForce™ is well-suited for mass production of thin-walled, complex-shaped insulation materials due to its high heat resistance and flame retardancy (certified to UL94 V-0 standards) derived from the material. It is formed by in-mold foaming using small-diameter beads as raw material. This allows for the mass production of insulation materials that fit the complex shapes of components.
For applying insulation to complex components, glass wool or urethane foam is commonly hand-applied by workers. However, using SunForce™, not only enhances heat management efficiency through high thermal insulation but also contributes to condensation prevention, reduction of the number of parts (saving labor and costs), and improved productivity and assembly precision (ensuring stable product quality) during assembly.
These characteristics allow SunForce™ to be applied across a wide range of fields that require high performance and high safety, such as cooling components for automobiles, cooling parts for 5G/6G communication devices and solar power conditioners, water cooling components for data centers and AI servers, engine oil separators, and air conditioning ducts.
Sample application 2
Thermal insulation materials for high temperature and high humidity environments
SunForce™ is also suitable for heat management in high temperature and high humidity environments such as washing and drying machines. In a simulation of application to a drum-type washer-dryer, it was found that the high insulation properties of this product help maintain the temperature inside the drum during drying operation, reducing energy loss, as shown in the figure below.
Sample application 3
Heat shielding material using SunForce™
Our first example uses SunForce™ heat shields to achieve thermal insulation in an electronic circuit board with highly heat-emitting components (such as might be found in a PCS unit in a solar-power generator).
The excellent thermal insulation, extensive shape flexibility, flame retardance, and heat resistance of SunForce™ foams make them ideal materials for heat shields to isolate heat-emitting regions from non-heat-emitting regions of electronic circuit boards.
