Solvay Launches Advanced PPAs for 800 V e‑Motor & Inverter Busbars

Solvay has introduced a new generation of high‑performance Polypropylene Amorphous (PPA) materials engineered for 800‑volt and higher e‑motor and inverter busbars. The portfolio, part of Solvay’s commitment to electrified mobility, delivers superior electrical integrity, thermal resilience, and sustainability for demanding power‑electronics components.

• Amodel PPA AE 9933 / AE 9950 – Designed for busbars operating at 800 V and above, these grades combine industry‑leading Comparative Tracking Index (CTI) ratings with exceptional thermal‑cycle shock resistance from –40 °F to 302 °F. They maintain CTI performance even after transient exposure to peak temperatures exceeding 302 °F, a significant advancement over conventional PPAs.
• Amodel Bios HFFR R1‑133 / R1‑145 – Halogen‑free, flame‑retarded grades that support the integration of e‑motors, power electronics, and gearboxes into a single, compact electric‑drive architecture. With CTI >600 V, heat resistance >248 °F, and excellent dimensional stability, these materials enable ultra‑miniaturised components while meeting UL94 V0 flammability standards without halogenated additives, reducing electronic corrosion risk.
• Amodel Bios AE R1‑133 – An electro‑friendly PPA formulated for surface‑mounted data connectors. Its higher impact resistance and weld‑line strength allow a 50 % reduction in wall thickness, slashing board‑footprint and creating space for additional electronics.

Solvay positions Amodel PPA Supreme as the market’s highest‑performance thermal and electrical PPA, whereas Amodel PPA Bios features a partially bio‑based, long‑chain molecular structure with the highest glass‑transition temperature (Tg) and the lowest global warming potential (GWP) among bio‑sourced PPAs.

Aligned with its One Planet sustainability pledge, Solvay has cut the CO₂ footprint of Amodel by 30 % since 2013 and produces PPAs in Augusta, Georgia, using 100 % renewable energy.
