A silicone-free, one-component thermal cure-in-place material

The Chomerics Division of Parker Hannifin Corporation, specialist in motion and control technologies has launched a one-component THERM-A-FORM thermally conductive cure-in-place material.

This is compatible with lean manufacturing processes used by automotive manufacturers to assemble large, high-voltage battery packs.

Featuring thermal conductivity of 3.0W/m-K, the THERM-A-FORM CIP30-U requires no mixing or on-site formulation by the user. Supplied in a ready-to-dispense form, it requires much less preparation time than traditional dual-component gels and is said to eliminate the risk of operator error when mixing components. It contains no silicone and is RoHS-compliant.

Chomerics THERM-A-FORM cure-in-place thermally conductive materials are said to provide a high-performance thermal interface between an electric vehicle’s (EV) or hybrid electric vehicle’s (HEV) lithium-ion traction battery modules and the battery enclosure. Chomerics thermal interface materials are also designed to provide a thermal interface for electronic control units and modules.

Unlike thermal pads and gap fillers, which are commonly used thermal interface materials, THERM-A-FORM and THERM-A-GAP gel may be applied by dispensing equipment, operating as part of an automotive system manufacturer’s automated production line. In addition, it conforms readily to the shape of a battery module without imposing mechanical strain on the battery assembly.
