Polyplastics Sees Strong Potential for POM and PP in Thermal Management Systems for EVs
TOKYO, Nov. 7, 2023 /Kyodo JBN-AsiaNet/ --

The Polyplastics Group, a leading global supplier of engineering 
thermoplastics, has introduced an approach of using its less heat-resistant 
plastics products for EV cooling components. Polyplastics sees strong potential 
for less heat-resistant plastics such as polyoxymethylene (POM) and 
polypropylene (PP) for production of EV cooling components.

As the automotive industry moves from traditional combustion engine vehicles to 
battery electric vehicles (BEVs), OEMs and parts manufacturers are reimagining 
the types of materials that can meet the thermal management needs of EVs. 
Polyplastics believes that less heat-resistant plastics like POM and PP have a 
significant potential for manufacturing EV cooling components.

The coolant in combustion engines is typically maintained at a temperature of 
70-100 C but can climb to 120 C or higher if the engine overheats. Therefore, 
metals or highly heat-resistant plastics like polyphenylene sulfide (PPS) are 
used in cooling components and lines. In comparison, EVs require a long-life 
coolant (LLC) temperature of 100 C or lower. This allows for the use of less 
heat-resistant materials for BEV-specific components. 

When the temperature of a LLC is 100 C or lower, general-purpose engineering 
plastics like POM or PP can be used instead of metals or high-performance 
engineering plastics. In the case of PP, Polyplastics sees potential for PP-LGF 
(long glass fiber) instead of short glass fiber to increase strength, 
dimensional accuracy, and overall performance. It also offers DURACON (R) 
bG-POM made with biomass as an eco-friendly option.

Replacing highly heat-resistant plastics such as PPS with POM and PP not only 
reduces material costs but also helps with efforts to reduce CO2 by reducing 
the carbon footprint of materials and energy consumption during molding.
