The Industry’s highest performing PPA

Amodel® Supreme: The Ultimate in PPA Performance

Syensqo commercialized the industry’s first PPA in 1990, and now we’ve introduced the industry’s best PPA: Amodel® Supreme.  

Amodel® Supreme is a new PPA polymer that boasts the industry’s highest Tg of 165°C, giving design engineers a wider temperature range without encountering a thermal transition, easing some design considerations. The high Tg also helps to deliver higher mechanical performance than traditional PPA between 140-200°C.  

Amodel® Supreme also improves electrical property performance, including volume resistivity and dielectric strength above 150°C.  Additionally, these increased electrical properties are retained after heat aging. This creates new opportunities for PPA to be used in higher voltage electric systems, such as next-generation e-motors, inverters and power electronics.

Metal Replacement, Structural & Electrification

Amodel® Supreme products are based on our new 9000 Series base resin. These materials are an important addition to our growing portfolio of standard, structural and electrically-friendly grades, extending the performance capabilities of PPA beyond 150°C. All of these materials provide excellent glycol resistance.
