1. Product Overview

BERGQUIST SIL PAD TSP PP1200 (also known as BERGQUIST POLY-PAD 1000) is a polyester-based, thermally conductive insulation material reinforced with fiberglass. It is ideal for applications requiring non-silicone conformal coatings and high thermal performance.

  • Technology: Polyester-based
  • Appearance: Yellow
  • Reinforcement: Fiberglass
  • Total Thickness: 0.229mm (ASTM D374)
  • Operating Temperature Range: -20°C to 150°C
  • Key Benefits:
    • Low thermal impedance (0.82°C-in²/W @ 50 psi)
    • Suitable for silicone-sensitive applications
    • High thermal conductivity (1.2 W/m-K)

2. Applications

  • Power supplies
  • Automotive electronics
  • Motor controls
  • Power semiconductors

Specialty Use Cases:

  • Ideal for telecom and aerospace applications where silicone contamination is a concern
  • Works well with conformal coatings
