Conductive Materials
Protecting today’s electronics to enhance performance and reliability
Heat and electromagnetic interference (EMI) are enemies of today’s electronics, but thermally and electrically conductive materials can help you win the battle and enhance reliability for even the most sensitive electronic applications.
For powerful protection from heat
Thermally conductive silicones from Dow come in a wide range of viscosities, cure speeds and delivery systems to address the growing need for higher-performance and more cost-effective thermal management in electronics designs for virtually every industry.
Gap Fillers and Gels
Thermally conductive gap fillers and gels are easy-to-use, soft, compressible, stress-relieving and vibration-damping materials with minimal process preparation requirements. They offer excellent long-term durability in application, maintain low-stress interfacial contact and feature thixotropic characteristics benefiting processability and vertical hold stability. Gap fillers are an excellent choice for applications with large gap tolerances (typically 150 μm to 2 mm).
