POLYPAD400 Datasheet, PDF (1/2 Pages) List of Unclassifed Manufacturers – Polyester based

Poly-Pad^® 400
PRODUCT DESCRIPTION
Polyester-Based, Thermally
Conductive Insulation Material
FEATURES AND BENEFITS
• Thermal impedance: 1.13°C-in²/W
(@50 psi)
• Polyester based
• F or applications requiring
conformal coatings
• D esigned for silicone-sensitive
standard applications
Poly-Pad^® 400 is a fiberglass-reinforced
insulator coated with a filled polyester
resin. Poly-Pad^® 400 is economical and
designed for most standard applications.
Polyester-based, thermally conductive
insulators from Bergquist provide a
complete family of materials for
silicone-sensitive applications.
Poly-Pads are ideally suited for
applications requiring conformal
coatings or applications where silicone
contamination is a concern (telecomm
and certain aerospace applications).
Poly-Pads are constructed with
ceramic-filled polyester resins coating
either side of a fiberglass carrier or a
film carrier. The Poly-Pad^® family offers
a complete range of performance
characteristics to match individual
applications.

1) The ASTM D5470 test fixture was used. The recorded value includes interfacial thermal resistance. These values are provided for
reference only. Actual application performance is directly related to the surface roughness, flatness and pressure applied.
TYPICAL APPLICATIONS INCLUDE
• Power supplies
• Automotive electronics
• Motor controls
• Power semiconductors
CONFIGURATIONS AVAILABLE
• Sheet form, die-cut parts and roll form
