Polyonics thermal interface materials provide electronics designers and manufacturers with a unique blend of low impedance and high temperature resistance not typically found in other products. The materials offer no pump-out or delamination plus dimensional stability and conformability after long term exposure up to 250°C (tested to 1000hrs). The Polyonics thermal interface materials include double liners for ease of assembly and die cutting.
Polyonics thermal interface materials are silicone based, come in a variety of thicknesses and have a light tack at room temperature for ease of pre-assembly. The silicone includes proprietary thermal conductive fillers and produces thin, uniform bond lines. The thermal interface materials are available with a variety of carrier films to address specific application needs.

- ESD-Safe™ (per (ANSI/ESD S20.20, IEC 61340 and JEDEC JESD 625B)
Polyonics has worked with leading ESD expert, consultants within the electronics community and S20.20, 61340 and JED625B standards committees to develop a comprehensive white paper. The paper defines the ESD problem, describes the test standards, and offers guidance on how to best reduce ESD risks associated with using process required insulators around static sensitive devices. The paper and supporting third party data are available as downloads from this page.

- Consumer Electronics
Polyonics thermal interface materials are designed specifically for thermal management applications that also involve exposures to high temperatures and where electrical isolation is not required. The materials remain dimensionally stable, maintain their thermal properties and are mess-free with exposures to 250°C. They offer a higher performance alternative to thermal greases, phase change materials, elastomeric pads and thermal bonding tapes. Mechanical fasteners are recommended for high temperature applications.
