R10404 is a thermally conductive closed cell silicone sponge rubber. This material offers thermal conductivity, electrical isolation, and compression set resistance (vibration absorptions). R10404 is the superior choice for battery pack gap filling, optimizing the efficiency and extending the service life of the individual battery cells.
Features / Benefits
- Silicone based, for long life and temperature stability
- Closed cell sponge structure, for compression set resistance, critical for vibration control
- Thermally conductive
- Electrical isolative
- Conforms to irregular (cylindrical and other) surfaces
Applications
- Lithium Ion Battery Pack
- Electrical Modules for Power Devices for Power Supplies
- Computers
- Telecommunication
- Automotive Electronics
- Electrical Insulation
- Military
- Medical
- Heat Pipe Assemblies
- Press Pads
- Decal Transfer
Recommended Uses
R10404 is offered to fill the needs of an unsupported thermal transfer material in applications requiring clean release, enhanced thermal performance by filling air gaps, electrical isolations and vibration cushioning.
Availability
R10404 is available in both sheets 36″ x 36″ and yard goods 36″ wide. Material can be supplied with an aggressive acrylic pressure sensitive adhesive or high temperature silicone adhesive on one side. Non-standard thicknesses available. Extra firm grade also available in 1/32″ thickness
