Solvay Expands its Range with Kalix High-Performance Polyamides

Solvay Specialty Polymers has introduced a new family of Kalix high performance polyamides (HPPAs) for structural components used in mobile healthcare (mHealth) electronic devices.

According to Solvay the new products, which include the Kalix HPPA 5000 halogen-free series and bio-based Kalix HPPAs, deliver high strength, stiffness, and improved chemical resistance versus traditional polycarbonate (PC) or PC/acrylonitrile-butadiene-styrene (ABS) materials, which are typically used for covers and housings form Health electronic devices.

The new Kalix HPPAs, which the company explains were first launched for smart mobile electronics at K 2013 in Germany last October, are a unique offering targeted for frames and covers for healthcare displays, terminals, and modules along with chassis, housings, and bezels for mHealth devices.

"This material introduction strengthens our commitment to both the healthcare and mobile electronics

industries,” said Maria Gallahue-Worl, Global Healthcare Business Manager for Solvay Specialty Polymers. “We’ve leveraged our extensive know-how in polymer technology and our long-term presence in healthcare to give our customers a competitive edge in meeting their end-use requirements.”

The company further explains that its Kalix 5950 HFFR’s high flow and low moisture absorption make it particularly suited for injection moulding large structural components such as frames and covers for displays, terminals, and modules that require strength, rigidity, and exceptional dimensional stability.

It claims the Kalix 5950 HFFR has received an Underwriters Laboratories (UL) 94 flammability rating of V0 for electrical/electronics applications for thicknesses of 0.4 mm and above and 5VA at thicknesses of 1.5 mm and above (both ratings are for all colours). The 50% glass fibre-reinforced grade provides greater mechanical properties than competing HFFR polyamides, and serves as an alternative to metals. Its mechanical properties include a tensile modulus of 20 GPa (2900 kpsi) and tensile strength of 250 MPa (36 ksi).

Solvay states it has also introduced a new portfolio of bio-based HPPAs designed for healthcare OEMs which want to incorporate renewable, bio-based polymers for mHealth devices. This includes the Kalix HPPA 3000 series, the first bio-based amorphous PPA, and the Kalix 2000 series, a family of bio-sourced PPA grades that provide outstanding impact resistance.

It claims the Kalix 3000 series is the industry’s first bio-based amorphous PPA. It states the two new grades – Kalix 3850 and Kalix 3950 – provide less warp, reduced shrinkage, and low to no flash.

Solvay further states the new Kalix 2000 series, based on PA 6,10, consists of Kalix 2855 and Kalix 2955. They provide strong mechanical properties, high impact strength, an exceptional surface finish, and low moisture absorption. These two compounded grades consist of 27% renewable content according to ASTM D6866.

The company explains that both the Kalix 2000 and 3000 series contain monomers that come from the sebacic acid chain which is derived from non-food competing and GMO-free castor oil. The new Kalix HPPA materials are available globally and Solvay is currently seeking qualifications with leading manufacturers of mHealth electronic devices.
