New Halogen‑Free, Flame‑Retardant Glass‑Reinforced Nylon 66 Compounds from Teknor Apex for Automotive, Appliance, and Electronics Applications

Teknor Apex has launched three halogen‑free, flame‑retardant glass‑reinforced nylon 66 (PA66) compounds—A3H7G3, C3H2G4, and C3H2G6—each achieving a UL94 V0 rating. These materials combine high melt flow, superior surface finish, and robust property retention, outperforming conventional glass‑filled FR nylon 66 in injection‑molding environments.

Each grade is available at glass loadings of 15%, 20%, and 30% respectively, enabling designers to tailor mechanical performance while meeting stringent regulatory standards. The non‑halogen formulations ensure compliance with EU RoHS and WEEE directives, as well as OEM requirements that mandate halogen‑free flame retardancy.

Teknor Apex recommends these compounds for a wide range of end‑uses, including appliance and power‑tool housings, handheld electronic devices, charging infrastructure for electric vehicles, and specific under‑hood automotive components that require flame‑retardant properties.

“We’ve leveraged semi‑aromatic nylon chemistry to enhance the ability of these compounds to retain tensile strength and stiffness in humid environments,” explains Mike Anderson, Commercial Director, ETP. “The A3H7G3 grade is already deployed in an automotive engine cover that met an OEM spec for property retention after heat aging at 170 °C (338 °F).”

For the 20% glass‑reinforced C3H2G4 grade, a comparison of dry‑as‑molded versus conditioned properties reveals notable shifts: notched Izod impact strength rises from 7 kJ/m² to 10 kJ/m²; tensile strength drops from 125 MPa to 85 MPa; elongation at break increases from 3.0% to 3.4%; and tensile modulus decreases from 8,300 MPa to 5,500 MPa.

Pratik Shah, Director of Strategic Initiatives, adds, “These compounds empower engineers to meet increasingly stringent halogen‑free FR requirements while enabling part consolidation. We offer halide‑free stabilization grades tailored for sensitive electronics where ion migration could trigger failures. Our expanding portfolio includes nylons, PBT, PPA, and even PP, with several new grades close to market launch. Our vision is a polymer‑neutral approach that delivers optimized solutions for each customer’s unique challenges.”

With these advanced, halogen‑free, flame‑retardant PA66 compounds, Teknor Apex delivers a reliable, compliant, and high‑performance solution for the next generation of automotive, appliance, and electronic components.
