Perstorp expands data center liquid cooling portfolio

Built for performance. Designed for confidence. 

Perstorp is launching the Synplate™ line of synthetic dielectric fluids for cold plate cooling, developed to support the growing demand for cold plate cooling in high-performance data centers. The Synplate™ fluids are engineered to deliver reliable heat transfer, strong dielectric performance, and broad material compatibility, helping ensure safe, efficient, and long-lasting operation. 

• Synplate™ DC: A first-of-its-kind dielectric fluid designed for reliable thermal performance and material compatibility in cold plate cooling systems, supporting high-performance electronics and simplifying thermal management  

In addition to the expansion of the indirect cooling market, the needs of the immersion cooling have grown and diversified. In response to this, Perstorp has expanded its offering to accommodate the needs of different data centers with new products in the Synmerse™ DC line: 

• Synmerse™ DC-L: An ultra-low viscosity fluid designed for exceptional thermal performance. It enables fast, efficient heat transfer in high-density environments and features a strong sustainability profile, including biogenic carbon content  
• Synmerse™ DC-Lx: An ultra-low viscosity fluid with material compatibility for current generation hardware systems with excellent thermal performance  
• Synmerse™ DC-R: Designed for data centers with the highest fire safety requirements, it has a high flash point (over 260°C, which meets the requirements of the Japanese Fire Service Act (消防法 ) ) while maintaining a balanced viscosity 

“Since the launch of Synmerse™ DC in 2024, we have been consistently collaborating with our partners in the data center ecosystem to look for new ways to make data center operations more sustainable, safer, and cost-effective.” says Dr. Valentina Serra-Holm, Head of Engineered Fluids Solutions at Perstorp. “Data centers are looking for cooling fluids that deliver high performance, a strong safety profile, and credible sustainability claims. With Synplate™ DC and the new Synmerse™ DC grades, we give our partners the tools to scale liquid cooling with confidence.”

Proven chemistry, real-world validation 

The new Synmerse™ DC grades build on the success of Synmerse™ DC, which has been rigorously tested in collaboration with leading OEMs and ODMs. The portfolio is designed to ensure long fluid lifetime, material compatibility with next-generation hardware, and low maintenance requirements, helping reduce downtime and total cost of ownership. All fluids are PFAS-free, engineered with safety in mind, and developed to support lower environmental impact across the value chain. 

Experience the solutions live at Data Centre World London 2026

Perstorp will showcase fully operational immersion and cold plate cooling systems using the new Synmerse™ DC and Synplate™ DC fluids at Data Centre World London 2026. At the Perstorp booth E192, visitors will be able to experience the fluids in action and engage with Perstorp’s technical experts about performance, safety, and sustainability.  

Availability, testing, and collaborations 

Samples of the new Synmerse™ DC immersion cooling fluids and Synplate™ DC indirect cooling fluids are now available for testing and evaluation. Data center OEMs, ODMs, and technology partners are invited to contact Perstorp to request product information or initiate a technical trial.
