Parker Chomerics THERM-A-GAP™ T652 Thermally Conductive, Fully Cured, Dispensable Gap Filler
Categories:	Polymer; Thermoset; Silicone
Material Notes:	Description: THERM-A-GAP™ T652 material is a highly conformable, pre-cured, single-compound. This unique material results in much lower mechanical stress on delicate components than even the softest gap-filling sheets. It is ideal for filling variable gaps between multiple components and a common heat sink. Product Features: Dispensable; Fully cured; High and low volume package sizes for use with manual or automated meter-mix; No settling in storage; Highly conformable at low pressure; Ideal for gap sizes 0.2mm to 4mm and Available with 0.010” glass bead Typical Applications: Engine control unites (ECU’s); Transmission and control devices; electrical drives; Steering and braking systems; Memory modules; LEDs; Power conversion equipment; Power supplies and UPS and Power semiconductors.
