Corning 340 Silicone Heat Sink Compound — 5oz (142g) White Thermal Conductive Grease, Non-Flowing

Dow Corning 340 heat sink compound in a single 5 oz (142 g) tube. This white, one-part silicone grease provides a stable, non-flowing thermal interface for electrical devices, PCB assemblies and CPU/heat sink connections. It does not require curing or ovens, exhibits low bleed and high temperature stability, and helps move heat away from sensitive components to improve reliability. Key specifications: - Color: White - Package: one tube (5oz / 142g) - Composition: 1 part, non-curing, non-flowing - Dielectric Strength: 210 V/mil - Flash Point: >101.1 °C - Specific Gravity: 2.1 - Thermal Conductivity: 0.67 W/mK - Viscosity: 542,000 - Volume Resistivity: 2 x 10^15 ohm-cm Application notes: Designed for thermal coupling between heat-generating circuitry and heat sinks, this thermally conductive compound increases heat transfer without the need for post-application curing, making it suitable for assemblers and field service on electronic equipment.
