Solvay launches Amodel® Supreme PPA for New E-Mobility Applications

Share to

Alpharetta, Ga., April 29, 2021 -- Solvay introduces Amodel® Supreme PPA, a new line of high-performance polyphthalamide (PPA) compounds designed for demanding e-mobility and metal replacement applications.

As the leading innovator in PPA chemistry and the first to introduce PPA to the market, Solvay’s Amodel® Supreme PPA brings a higher level of performance to systems requiring exceptional thermal, mechanical and electrical properties. Applications range from high-temperature automotive components used in electric drive units including e-motors, power electronics, housings for high-temperature electrical connectors, electric and electronic devices and telecommunication equipment components that need excellent heat resistance.

In addition, Solvay’s Amodel® Supreme PPA offers stiffness and toughness to replace metal in more traditional and structural applications such as clutch cylinders, shift forks and body in white.

Solvay Amodel® PPA has a 25 year history of performance in a variety of under the hood applications that have been converted from metal to plastic. Solvay’s new Amodel® Supreme features the PPA industry’s highest glass transition temperature (Tg) of 165°C which enables higher mechanical performance vs. traditional PA4T and PA6T based materials at elevated temperatures. There is also a greater Coefficient of Linear Thermal Expansion (CLTE) match to metals that allows for ease in designing overmolded components.   

In addition to exceptional thermo-mechanical performance, Amodel® Supreme PPA features improved electrical properties, including volume resistivity and dielectric strength above 150°C.  These materials also maintain critical electrical properties, like comparative tracking index (CTI), after exposure to high temperatures over time. Compounds were designed to ensure hydrolytic stability against new EV cooling fluids. 

“Solvay continues to achieve new performance milestones for our Amodel® PPA family of technologies to meet our customers’ increasingly stringent requirements,” said Brian Baleno, Head of Marketing-Transportation at Solvay Specialty Polymers. “Industries from automotive to electronics to telecommunications are raising the bar for properties such as heat resistance, strength, stiffness and electrical performance. Now, with the launch of Amodel® Supreme PPA, we can meet or even surpass these high expectations and offer customers a new alternative to traditional metal and conventional polymers.”  

The initial launch of Amodel® Supreme PPA includes six grades. They are divided into standard, structural and electrical products. These grades are available globally.
