On May 11, Solvay announced the market launch of Amodel® Supreme PPA (Ultra High Temperature Polyterephthalamide), Solvay’s engineered product for demanding e-mobility and metal replacement applications.
New high performance PPA material
.
As a leading innovator in PPA chemistry, and the first to market PPA, Solvay's Amodel® Supreme PPA delivers superior performance for systems requiring outstanding thermal, mechanical and electrical performance
.
The application range of this material covers high temperature components of various automotive electric drive units, including electric motors, power electronic components, high temperature electronic connector housings, and electrical and electronic equipment and telecommunication equipment components that require excellent high temperature resistance.
.
In addition, Solvay's Amodel® Supreme PPA provides excellent stiffness and toughness to replace metal in traditional applications and structural components such as clutch wheel cylinders, shift forks, and white housings
.
Solvay's Amodel® PPA has been used for 25 years in various components under the hood of automobiles, where it has successfully replaced metal with plastic
.
Solvay's full Amodel® Supreme has the highest glass transition temperature (Tg) for PPAs currently on the market at 165°C, which makes it superior at high temperatures compared to traditional PA4T and PA6T based materials.
Better mechanical performance
.
At the same time, the coefficient of linear thermal expansion (CLTE) match to the metal is greatly improved, which reduces the difficulty of designing overmolded components
.
In addition to excellent thermomechanical properties, Amodel® Supreme PPA has further improved electrical properties, including volume resistivity and dielectric strength above 150°C
.
The material retains key electrical properties such as relative tracking index (CTI) after prolonged exposure to high temperatures
.
In addition, it can also maintain good hydrolytic stability when dealing with new electric vehicle coolants
.
In addition, Amodel® Supreme PPA's first-release lineup includes 6 grades in conventional, structural and electrical categories that will be available globally
.
