Electrolube’s Polyurethane Resin A Success for Tier 1 Automotive Provider


MacDermid Alpha Electronics Options is happy to announce a profitable collaboration between its electro-chemicals model, Electrolube, and a tier 1 automotive provider. The automotive buyer discovered a really perfect manufacturing companion in Electrolube, whose UR5608 powerful polyurethane potting and encapsulation compound proved the very best resolution for safeguarding their on-board charger.

The automotive provider was initially on the lookout for a thermal administration materials to fill air gaps, and dissipate warmth, between the PCB and cooling channels of their on-board charger. They believed that they wanted a fabric with thermal conductivity within the area of 4-6 W/m.Ok. After additional dialogue to know the appliance in additional element, Electrolube decided that the automotive buyer had scorching spots on their PCB when a thermal administration materials was used. This was brought on by the excessive viscosity of those merchandise and the very small gaps within the on-board charger that the fabric wanted to stream into, which left air pockets remaining after filling. Air is a poor conductor of warmth, approx. 0.025 W/m.Ok, and subsequently the remaining air pockets lowered the effectivity of warmth switch.

Electrolube proposed taking a look at a thermally conductive resin with decrease viscosity and higher stream properties, to have the ability to fill even the smallest gaps within the unit extra successfully. Moreover, the shopper additionally wanted excessive dielectric energy, wonderful safety to automotive fluids and assist towards vibration, while additionally providing flexibility for fragile elements throughout thermal shock. These particular necessities led Electrolube to counsel the versatile UR5608 polyurethane resin that gives wonderful stream even in small (~0.5mm) spacings, with combination of assist and suppleness. UR5608 delivers a dielectric energy of 18 kV/mm and is UL94 V-0 authorized Regardless of the resin having a decrease thermal conductivity of 0.78 W/m.Ok than the unique specification, the low viscosity UR5608 proved to be extremely profitable at eliminating any air gaps within the system, which dramatically lowered the thermal resistance.

The automotive buyer examined UR5608 and Electrolube labored with them to realize essentially the most environment friendly manufacturing processes by recommending gently heating the fabric and potting the unit at a slight angle to additional enhance stream and flush out all air pockets from the unit. When examined, UR5608 flowed properly by means of the shopper’s unit, and so they achieved the warmth dissipation that was required. UR5608 was subsequently authorized for the appliance after demonstrating efficient warmth switch between sure scorching elements, inductors and capacitors, and the liquid cooling channels inside their aluminium metallic casing.
