Polyplastics, a Japanese engineering plastics manufacturer, has recently introduced a new glass-filled polyphenylene sulfide (PPS) grade known as DURAFIDE PPS 1140HS6. This new grade is specifically designed to meet the requirements for metal insert molding, particularly for electric vehicle (EV) busbars. The goal of this new product is to limit molding imperfections and enhance performance in EV busbar applications without the need for impact modifiers.
Insert-molded EV components are typically made from a combination of metal that conducts electric power and PPS resin that acts as a coating for insulation. However, repeated heating and cooling can lead to cracking, compromising the insulation and potentially causing failures in critical parts of EVs that carry high-voltage currents. The addition of impact modifiers to PPS resin can decrease material strength and result in the emergence of gas and mold deposits during molding, making the material difficult to recycle.
One of the key advantages of the DURAFIDE PPS 1140HS6 grade is that it can be seamlessly collected during recycling without the need for separation from other PPS components. This not only streamlines the recycling process but also promotes sustainability by ensuring that the material can be effectively reused. The new resin also offers improved flowability during injection molding compared to standard materials, making it suitable for molding both thin-wall and large products.
This innovative PPS grade by Polyplastics provides a solution to the challenges faced in metal insert molding applications, particularly in the production of EV busbars. By eliminating the need for impact modifiers and improving the material’s flowability, the DURAFIDE PPS 1140HS6 enhances the performance and durability of molded components in EVs. Additionally, its recyclability and compatibility with other PPS components make it an environmentally friendly choice for manufacturers looking to reduce waste in their production processes.
Overall, the introduction of the DURAFIDE PPS 1140HS6 by Polyplastics marks a significant advancement in the field of engineering plastics. The development of a glass-filled PPS grade that meets the requirements for metal insert molding in EV busbars demonstrates the company’s commitment to innovation and sustainability. By addressing the challenges associated with molding imperfections and recycling issues, Polyplastics is contributing to the advancement of technologies in the automotive industry, particularly in the production of electric vehicles.
