SPA-SP300 Thermal Insulation Sheet | Boron Nitride Filled | TOUSEN

The SPA-SP300 Thermal Insulation Sheet is a boron nitride filled non-silicone material designed for electronic applications requiring high thermal conductivity and electrical insulation. This insulation sheet delivers 15W/m·K thermal conductivity, ensuring efficient heat dissipation while maintaining high breakdown voltage exceeding 10kV/mm for operational safety. With low density of 1.50±0.10 g/cm³ and low dielectric constant ≤3.50 at 5GHz, the material minimizes signal loss in high-frequency applications.

This boron nitride filled insulation sheet offers thickness options of 0.20mm, 0.30mm, and 0.50mm, with corresponding thermal impedance values of 0.05, 0.08, and 0.15°C·in²/W at 15psi. It features high volume resistivity >10¹³ Ω·cm for excellent electrical isolation and Shore A hardness of 85±5 for mechanical durability. The sheet's flexibility and optional adhesive backing facilitate easy installation in various configurations.

Applications include electric vehicle battery packaging, high-power supply systems, high-voltage equipment, and communication devices. The thermal insulation sheet operates reliably across -40°C to 120°C and complies with RoHS, Halogen-Free, and REACH standards. Its combination of high thermal conductivity and electrical insulation makes it ideal for advanced thermal management solutions.
