The new Gap Pad I000SF is a thermally conductive, electrically insulating, silicone-free polymer specially designed for silicone-sensitive applications.The material is ideal for applications with high standoff and flatness tolerances. Gap Pad I000SF is reinforced for easy material handling and added durability during assembly The material is available with a protective liner on both sides of the material.
Note: Resultant thickness is defined as the final gap thickness of the application.
Typical Applications Include:
• Digital disk drives / CD-ROM
• Automotive modules
• Fiber optics modules
Configurations Available:
• Sheet form
• Die-cut parts
