Full Product Description

Parker Chomerics THERM-A-GAP™ 579 Thermally Conductive Gap Filler Pads provide a low hardness (30 Shore 00) solution with 3.0 W/m-K of thermal conductivity. THERM-A-GAP 579 series gap-filler sheets and pads offer excellent thermal properties and the highest conformability at low clamping forces. THERM-A-GAP 579 is a combination of excellent thermal performance and conformability while possessing the lowest outgassing.


THERM-A-GAP 579 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.


Be sure to write in the comments section, upon check out of your quote request, which custom size dimensions you need. Our team will then reach out for your specific drawing to complete your quote request.


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.
• PN – PEN film - polyethylenenapthalate - this carrier permits the gap pad to see a shearing motion and offers a clear, cost effective dielectric film with fair thermal performance.
• KT – thermally enhanced polyimide – this carrier permits the gap pad to see a shearing motion and offers an excellent dielectric film with enhanced thermal performance.
• 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.


Features and Benefits:
• Ultra low deflection force requirements
• High thermal conductivity
• High tack surface reduces contact resistance
• UL 94 V-0 flammability rated
• RoHS compliant


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