Shin-Etsu X-23-7921-5 Thermal Grease for High-Performance Processors

Product Introduction: Shin-Etsu X-23-7921-5 Thermal Grease

Basic Properties

Shin-Etsu X-23-7921-5 is a non-solvent thermal interface material designed for high-performance microprocessors. It fills air gaps between processors and heat sinks to enhance thermal efficiency, featuring high thermal conductivity (>6.0 W/m·K) and low thermal resistance (<7.0 mm²·K/W). The gray paste has a viscosity of 360 Pa·s at 25°C.

Product Description

Developed by Shin-Etsu Chemical, X-23-7921-5 minimizes interfacial thermal resistance by evenly coating processor-heat sink interfaces. Its formulation achieves a bond line thickness (BLT) of 25μm at 20psi, with minimal volatility (0.44% after 24hrs at 50°C). Available in syringes, cartridges, and bulk packaging for manual or automated applications.

Key Features

• High Thermal Conductivity: >6.0 W/m·K, far surpassing air (0.027 W/m·K).
• Low Thermal Resistance: <7.0 mm²·K/W at 20psi.
• Stability: Specific gravity 2.5 with low volatility for long-term reliability.
• Precision Compatibility: BLT maintained at 25~41μm under 5.2~52.2psi pressure.

Applications

Applications include CPU/GPU cooling, servers, automotive electronics, and high-power LED modules. Its low thermal resistance suits thin-profile devices (e.g., laptops) and industrial equipment requiring sustained high-temperature operation.
