Solvay Launches New Amodel® Supreme and Bios Materials to Support Sustainable Innovation in Electric Vehicles

Solvay is accelerating the supply of a new generation of Amodel® PPA (polyterephthalamide) materials to the automotive industry, designed to meet the higher performance and sustainability demands of electrical and electronic applications in electric vehicles
.

Of these, Amodel® PPA AE 9933 and AE 9950 belong to the Supreme series for electronic motor and inverter busbars operating at 800 volts and higher
.
Both materials combine best-in-class relative tracking index (CTI) and high thermal cycle impact resistance from -40 to 150°C
.
Compared to traditional PPA technology, Amodel® PPA Supreme series grades are technologically breakthrough, maintaining CTI even after prolonged exposure to peak temperatures above 150°C

Solvay launches new Amodel® Supreme and Bios materials to further support sustainable innovation in electric vehicles
.

Solvay's new halogen-free flame retardant Amodel® Bios HFFR R1-133 and HFFR R1-145 meet the growing trend to integrate electronic motors, power electronics and gearboxes in a comprehensive electric drive system brought new demands
.
These materials have CTI values ​​>600 V, thermal resistance >120°C, and excellent dimensional stability, enabling the design of highly compact systems with miniaturized components
.
Also, they provide a UL94 V0 flammability rating without the need for halogen flame retardants
.
In addition to addressing safety concerns in the event of runaway thermal excursions, this halogen-free formulation minimizes the risk of additive ionization corrosion
.

In addition, Solvay offers Amodel® Bios AE R1-133, an electrical and electronically friendly material developed for surface mount data connectors that can withstand solder flow processes without blistering
.
The material's higher impact resistance and weld-line strength compared to common PPA enables designers to further reduce the wall thickness of the connector, thereby reducing the printed circuit board space it occupies by up to 50% for Additional electronics provide more space
.

Brian Baleno, Head of Transportation Markets at Solvay Specialty Polymers, said: "The Amodel® Supreme and Bios families are attracting great attention from designers of a variety of electronic propulsion systems, including electronic motors, power electronics and electronic cooling pumps
.

In addition to enhancing the thermal and electrical performance of EV components, adding value through these systems, new products in the Amodel® polymer family are also gaining attention from manufacturers as they meet their sustainability goals
.
"Press Release Amodel® PPA Supreme is considered to be the highest performing thermoelectric PPA currently on the market, while Amodel® PPA Bios has a partially bio-based long-chain molecular structure with a glass transition temperature ( Tg = 135°C) and the lowest global warming potential (GWP)
.

Solvay has reduced the CO2 footprint of Amodel® PPA by 30% since 2013, delivering on its One Planet sustainability commitment, producing the PPA at its global manufacturing facility in Augusta, Georgia 100% use of renewable energy
