BERGQUIST GAP PAD TGP 2400
FEATURES AND BENEFITS
- Thermal Conductivity: 2.4 W/m-K
- Low “S-Class” thermal resistance at ultra-low pressures
- Ultra conformable, “gel-like” modulus
- Designed for low-stress applications
- Fiberglass reinforced for puncture, shear and tear resistance
BERGQUIST GAP PAD TGP 2400 is a thermally conductive, reinforced material rated at a thermal conductivity of 2.4 W/m-K. The material is a filled-polymer material yielding extremely soft, elastic characteristics. The material is reinforced to provide easy handling, converting, added electrical isolation and tear resistance.
BERGQUIST GAP PAD TGP 2400 is well suited for low pressure applications that typically use fixed standoff or clip mounting. BERGQUIST GAP PAD TGP 2400 maintains a conformable yet elastic nature that allows for excellent interfacing and wet-out characteristics, even to surfaces with high roughness and/or topography.
BERGQUIST GAP PAD TGP 2400 is offered with inherent natural tack on both sides of the material allowing for stickin-place characteristics during application assembly. It is also
available with a non-tack side.
Please see the “Standard Options” section for description.
BERGQUIST GAP PAD TGP 2400 is supplied with protective liners on both sides. The top side has reduced tack for ease of handling.
