Potting & encapsulation

Peter Donaldson examines the finer points of potting and encapsulation Many electrical and electronic components last longer, perform better and stand up to the stresses and strains of hard use with fewer complaints if they are potted or encapsulated in a polymer. While the two terms are often used interchangeably,

DuPont’s resin helps extend the life of liquid cooling systems

DuPont AmberLite EV2X resin helps extend the life of an EV’s glycol coolant, coolant loop components and ion exchange filter. It reduces glycol maintenance requirements by offering enhanced thermal stability and excellent operating characteristics, compared with standard ion exchange resins on the market. Consumer demand for greater range, faster charging, larger vehicles and more energy-dense batteries is increasing temperatures within EVs, creating new challenges for vehicle manufacturers. Many are turning from air cooling to liquid systems that use glycol coolant to manage high temperatures.

AURUM thermoplastic polyimide offers Tg of 245 C

Electrical breakdown of high-temperature insulation materials can be prevented by using thermoplastic polyimide (TPI), a high-performance polymer. This is important with the transition to electric vehicles, with polymers that offer higher electrical and thermal properties being sought. To enable faster charging and travel over longer distances, electrical breakdown must be prevented by high-temperature insulation materials.

LFP cells charge in six minutes

DESTEN has developed the first Lithium Iron Phosphate (LFP) cell that can charge in just six minutes at 6 C writes Nick Flaherty. The 160 Wh/kg pouch cell developed by DESTEN is capable of charging from 20% to 80% SOC in six minutes at a charging rate of 6 C. Moreover, the LFP chemistry means the cell is intrinsically safer than lithium ion cells.
