POLYPAD1000 Datasheet, PDF (1/2 Pages) List of Unclassifed Manufacturers – Polyester based

Poly-Pad^® 1000
PRODUCT DESCRIPTION
Polyester-Based, Thermally
Conductive Insulation Material
FEATURES AND BENEFITS
• Thermal impedance: 0.82°C-in²/W
(@50 psi)
• Polyester based
• F or applications requiring non-silicone
conformal coatings
• D esigned for silicone-sensitive
applications equiring high performance
Poly-Pad^® 1000 is a fiberglass-reinforced
insulator coated with a filled polyester
resin. The material offers superior
thermal resistance for high
performance 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.
