The general trend has come, the "electrification" of automobiles is surging
In recent years, with the continuous tightening of carbon emission regulations and concerns about the energy crisis, the electrification of the automotive industry has continued to accelerate and deepen, and has become a globally recognized development direction
.
As the power system gradually changes from the internal combustion engine to the electric drive, the electrified vehicle presents different requirements and challenges to the engineering plastics for vehicles
.
Unlike traditional internal combustion engine systems, electric powertrains typically operate at high voltages of hundreds of volts, with currents as high as hundreds of amps, and some companies are striving to increase voltages to 1000V and even higher in pursuit of higher charging speeds and efficiencies.

DSM follows the trend and releases a white paper on next-generation materials
DSM follows the trend and releases a white paper on next-generation materials
Faced with the stringent requirements of electric vehicle powertrains, DSM has introduced a range of polyamides PA6, 46, 66, 666, 410, 410, aromatic polyamides PA 4T (PPA) and PA 4T (FoTii Ace), and PPS , PBT, PET and polyester-based thermoplastic elastomers (TPC) and other engineering plastic products
.
■ PA 4T (FoTii Ace): The glass transition temperature is 160oC.
In applications up to 150°C continuous use temperature, no thermal stabilizer is used to ensure the mechanical properties of polyamide, thereby avoiding core automotive components such as sensors and connectors.
Galvanic corrosion due to additives
.
■ Akulon PA66 and ForTii PPA:CTI are rated over 700V and 850V respectively, which can help design engineers to achieve more functions or design more electronic components in a small space, and also avoid the use of good packaging caused by cost
.
■ Xytron PPS: has good temperature and aging resistance, suitable for peak operating temperature over 200 ℃, and can be used in harsh environments containing corrosive chemicals, oils or other chemical agents

*DSM's cumulative sales in 2019 were EUR 9.
01 billion, an increase of 2% year-on-year, net profit was EUR 764 million, and adjusted net profit was EUR 830 million, an increase of 8% year-on-year
