XytronTM—the purest material solution with the highest durability on the market
Our researchers have concluded that polyphenylene sulfide (PPS) materials are best suited for PEMFCs. Xytron, our high-performance PPS compound, offers the high purity and superior mechanical strength needed to achieve the industry’s lowest ion leaching performance at temperatures up to 120°C, and highest hydrolytic and chemical resistance. This enables OEMs to develop long-lasting, highly efficient PEMFCs that lower the cost per kilometer and total cost of ownership for end users.
Outperforming every competitive material
Xytron offers unmatched strength and toughness retention, dimensional stability, fatigue and creep resistance, and weldline strength in hydrolytic environments, ensuring lifelong reliability in PEMFCs. DSM’s testing shows that after 200 hours, Xytron shows virtually no increase in mass due to water absorption, which is a key contributor to ionic leaching.
By comparison, polyamide (PA6) increased in mass by up to almost 10% & PPA in mass more than 5%. Testing also demonstrates that Xytron loses minimal mechanical strength after more than 5,000 hours of hydrolytic and heating aging, while PA groups shows significant deterioration after 150 hours and other PPS materials begin to deteriorate after less than 300 hours.
Dedicated fuel cell application expertise
DSM leverages extensive research, computer-aided engineering (CAE) and industry experts to validate Xytron’s performance in various PEMFC components. This enables our customers to design system parts, including media distribution plates, insulation plates, hydrogen recirculation components and hydrogen pressure regulation valves, using the same material, saving them time and costs. We provide customers with direct application design expertise and work with them to select the optimal material grades for their needs.
At DSM, we understand that making an impeccable first impression with a new product is critical. Although vehicle producers are eager to embrace green solutions, they require assurance that doing so won’t negatively impact their bottom line.
As a sustainability-driven company and the preferred partner of industry-leading vehicle, electronics and electrical industry manufacturers, DSM is ready to help you launch fuel cell technology that exceeds expectations. Our team is committed to helping you and your customers cultivate a cleaner, brighter future for everyone.
