Parker Chomerics THERM-A-GAP 580 Thermally Conductive Gap Filler
Categories: Polymer; Thermoset; Filled/Reinforced Thermoset; Rubber or Thermoset Elastomer (TSE)

Material Notes: THERM-A-GAP™ 580 is a highly conformal, thermally conductive gap filler pad. The materials consist of an ultra-soft silicone elastomer filled with ceramic particles. THERM-A-GAP™ elastomers are used to fill air voids between PC boards or high temperature components and heat sinks, metal enclosures, and chassis. The exceptional conformability of these advanced materials enables them to blanket highly uneven surfaces, wetting out mating surfaces in order to efficiently transfer heat away from components.

Typical Applications: Telecommunications equipment; Consumer electronics; Automotive electronics (ECUs); LEDs, lighting; Power conversion; Desktop computers; laptops, servers; Handheld devices; Memory modules and Vibration dampening

Product Attributes: Best for molding complex parts and vibration dampening and Lowest outgassing
