CHT SG502 Silicone Grease
Categories: Other Engineering Material

Material Notes: Description: This is a highly thermally conductive silicone grease / compound. This property together with a low moisture and metallic impurity content makes it a suitable heat sink product for a wide variety of applications within the electronics and electrical industries.

Key Features

  • Thermally conductive
  • Low volatility
  • Good dielectric and isolating properties
  • Low bleed even at elevated temperatures
Key Applications
  • Thermally Conductive
Application: This grease has a relatively soft consistency and high extrusion rate that facilitates application by syringe into small gaps. This allows it to be used when mounting semi-conductor devices on heat sinks, obviating air gaps between imperfectly mating surfaces. In this application, it may be used in conjunction with electrically insulating mica washers without increasing electrical leakage in any way. Used within a semi-conductor device casing it affords excellent shock protection for diode elements and provides protection against inadvertent contamination
