Japanese engineering thermoplastics supplier Polyplastics Group has unveiled its latest offering, Durafide PPS 6150T73, a high-performance material designed specifically for electric vehicle (EV) lithium-ion (Li-ion) batteries. This new material is known for its exceptional heat resistance, thermal and electric insulation properties, and is set to revolutionize the EV industry.
One of the key features of Durafide PPS 6150T73 is its ability to withstand thermal runaway, where Li-ion batteries can generate excessive heat leading to potential fires. The material is able to maintain its insulation properties even after exposure to temperatures as high as 1,000°C for 30 minutes. This is a significant improvement over existing solutions that rely on inorganic insulative sheet structures.
Traditionally, structural insulative sheets and plates have been used to reduce energy transfer between cells during a thermal runaway event. However, these add weight and consume space, making them less ideal for the compact design of EV batteries. Durafide 6150T73 offers a more lightweight and compact solution, without compromising on performance.
In addition to its heat resistance, Durafide 6150T73 offers optimal properties for components such as module covers and busbars. The material is made of high-purity linear PPS, which provides toughness and impact strength, while also exhibiting low ionic impurities. Its color is close to white but can also be tinted, allowing for further customization options.
Polyplastics Group’s Durafide PPS 6150T73 is the latest step towards enhancing the safety and performance of EV batteries. As the EV market continues to grow, it is crucial to develop materials that can withstand the unique demands of this industry. This breakthrough material ensures that EVs can operate at their full potential with reduced risk of thermal runaway incidents and improved overall safety.
