The Chomerics Division of Parker Hannifin Corporation, the global leader in motion and control technologies, is introducing THERM-A-GAP™ PAD 10, a series of thermally conductive gap filler pads for applications where high performance and ultra-low shore hardness are primary material requirements. Design engineers can benefit from the new pad’s 1.0 W/m-K of thermal conductivity and hardness of just 35 Shore 00 for the highest conformability at low clamping forces.

Gap filler pads serve as thermally conductive materials that sit between a heat-generating component, such as a semiconductor or battery, and a heat-dissipating surface. The new THERM-A-GAP™ PAD 10 is an ultra-conformable and cost effective gap filler sheet solution for use in applications featuring uneven component surfaces or tight spaces. 

Electronic products set to benefit include: complex PC and server assemblies, microprocessors and GPUs; high-power LED lighting; consumer electronics; automotive electronics such as ECUs and battery cells; telecommunications equipment; and power conversion electronics featuring intricate heatsinks.

Thermal gap pads are a preferred solution among product designers and engineers because of their design flexibility and ease of use. The new Parker Chomerics pads are RoHS-compliant and feature a high-tack surface to reduce contact resistance, an operating temperature range of -55°C to +200°C, a UL 94 V-0 flammability rating and are also electrically isolating. Electrical properties include: 8 kVac/mm dielectric strength (ASTM D149 test method); 1014 Ω-cm volume resistivity (ASTM D257); 5.3 dielectric constant at 1,000 kHz (ASTM D150); and 0.013 dissipation factor at 1,000 kHz (Chomerics TM-TP13 test method).

THERM-A-GAP PAD 10 is available in various thicknesses from 0.254 mm to 5.0 mm (in increments of 0.254 mm) and comes in standard sheets measuring 228.6 mm x 228.6 mm. Carrier substrate options include aluminium foil with a pressure sensitive adhesive (PSA) or woven glass without PSA. 

Custom size configurations and die-cut parts are available individually or on sheets. Design engineers can request quotes for custom sizes online simply by choosing the required thickness and carrier options, then selecting ‘custom’ size.
