High performance polyamides for structural components used in mobile healthcare electronic devices

19-Jun-14

A new family of Kalix high performance polyamides (HPPAs) for structural components used in mobile healthcare (mHealth) electronic devices has been developed by Solvay Specialty Polymers. 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. 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). "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.
