Thermal Interface Material
STP-30
Introduction

STP-30 is our standard thermal interface material grade. Thermal Conductivity
of 3.0W/mK.

The material is made of flexible silicone pad filled with Aluminum particles.
It has been designed for the best combination of thermal conductivity,
compressibility and self adhesiveness to achieve the best thermal transfer and heat dissipation performance.

Features
  • Excellent thermal conductivity
  • Very flexible.
  • Provides appropriate electric insulation.
  • Good compressibility. The material fills air gaps between heat sinks and
    heat emitting components on p.c.boards.
  • Excellent workability based on appropriate hardness and self-tackiness
  • Available in custom sizes and die-cut requirement
  • Less outgassing of low molecular siloxane
  • Variation in surface treatment: double sides tackiness, one side tackiness,
    with reignforcement.
Applications

1. Replacement for messy grease

2. Between heat dissipater and CPU/semiconductor or any heat emitting
    components

3. Power supply

4. High speed mass storage device

5. Various automotive electronics

6. LED lighting
