The new THERM-A-GAP GEL 20 from Parker Chomerics is a high reliability thermal interface material specially developed for the automotive industry.
The single-component GEL-20 has a mid-range thermal conductivity of 2.4 W/m-K and is therefore widely applicable.
The paste-like substance is easy and controlled to dispense in variable thicknesses up to a gap of 4 mm. Its optimum performance requires only a low compressive force, so the contacted components and solder joints experience minimal mechanical stress. The material is highly suitable for cyclic thermal fluctuations and continues to perform well even at high temperatures. This allows the material to meet the high requirements in the automotive market.
Other product properties:
– working range -55 to 200°C
– no secondary curing required
– low evaporation
– resistant to movement during vibrations
– superior adhesion
– consistent material with long-term reliability
Application include automotive infotainment systems, onboard chargers and inverters, engine management systems etc. but of course it’s very useful in other applications where cyclic heating, high temperatures and long-term reliability are required.
GEL 20 is available in many different packages from 10cc hand spray to 20 liter buckets.
