THERM-A-GAP 580 | Parker Chomerics
Parker Chomerics THERM-A-GAP™ 580 Thermally Conductive Gap Filler Pads provide a moderate hardness (75 Shore 00) solution with 3.0 W/m-K of thermal conductivity. THERM-A-GAP™ 580 series gap-filler sheets and pads offer excellent thermal properties and the highest conformability at low clamping forces. THERM-A-GAP™ 580 is best for molding complex parts and vibration dampening while also possessing the lowest outgassing.
THERM-A-GAP 580 is available in various thicknesses and finished in standard sheets of 9"x9" or 18"x18". Custom size configurations and die cut parts are available as individual parts or on sheets. To receive a quote on a custom size part, choose your thickness and carrier options, and then select “custom” size.

Available Carriers
- G – woven glass (no PSA) - this carrier option provides reinforcement and a clean break / low tack interface surface, allowing for re-use of the pad if necessary or for prototyping.
- A – aluminum foil (with PSA) - this carrier’s primary function is to allow a pressure sensitive adhesive on the gap pad.
- No carrier (no letter distinction) - the no carrier or “un-reinforced” option allows the gap pad to have high tack surfaces on both sides, allowing for the pad to be highly conformable, but it does make cutting and handling of the product more difficult.
