Solvay has extended its diversified portfolio of high-performance polyphthalamide (PPA) compounds with Amodel Bios, a new family of partially bio-based long-chain PPA products particularly indicated for demanding electrical and electronic applications in e-mobility. Besides its renewable feedstock content from non-food-competing sources, it is produced with 100% renewable electricity, minimizing its global warming potential (GWP) well below the level of other bio-based PPA.

Solvay’s Amodel Bios PPA combines sustainability with the requisite performance properties for components in e-motors, power electronics, and other high-end electrical systems. Most notably, it offers the highest glass transition temperature — Tg 135°C — of all bio-based PPA on the market and a melting point (Tm) of 315°C. Designed for injection molding, it is an ideal candidate for non-blistering reflow soldered surface mount devices (SMD) and parts in the cooling circuit of power electronics, including fluid connectors.

In addition, the limited moisture absorption of the new polymer versus standard PPA delivers a high level of dimensional stability at a low risk of stress corrosion, which is particularly important with regard to miniaturized electrical connectors. Amodel Bios PPA also provides good impact strength, even in halogen-free flame-retardant grades complying with UL94 V0, and is suited for colorable applications. This is complemented by high elongation, weld-line strength, and surface aesthetics.
