Japanese engineering thermoplastics supplier, Polyplastics Group, has unveiled Durafide PPS 6150T73, a revolutionary material specifically designed for the electric vehicle (EV) segment. This high-performance material offers exceptional heat resistance and outstanding thermal and electric insulation properties, making it ideal for lithium-ion (Li-ion) batteries used in EVs.
One of the key features of Durafide PPS 6150T73 is its ability to withstand thermal runaway without the need for inorganic insulative sheet structures. Thermal runaway can occur in Li-ion batteries when excessive heat is generated, often leading to potential fires in case of accidents. In such situations, the temperature of a LIB cell can reach a staggering 800° to 1,000°C, and the gases emitted can reach 700° to 800°C. Durafide PPS 6150T73 performs exceptionally well even in such extreme conditions.
Additionally, Durafide PPS 6150T73 maintains its insulation properties for busbars and module covers, even after exposure to environments with temperatures as high as 1,000°C for 30 minutes. This ensures the safety and stability of the battery components.
Traditionally, insulative sheets and plates have been used to prevent energy transfer between neighboring cells during thermal runaway events. However, these structures add weight and consume more space due to the increase in the number of parts. Durafide PPS 6150T73 offers a more compact and lightweight alternative, making it an optimal choice for the EV industry.
Apart from its exceptional heat resistance, Durafide PPS 6150T73 also possesses ideal properties for various battery components, including busbars and module covers. As a high-purity linear PPS, it provides excellent toughness and impact strength. It also exhibits low ionic impurities, ensuring better performance and longevity of the battery system.
With its close-to-white color, Durafide PPS 6150T73 offers aesthetic appeal and can also be tinted according to specific requirements. This versatile material from Polyplastics Group is a significant advancement in battery technology and contributes to the ongoing development of safer and more efficient electric vehicles.
