Avient expands non-halogen flame retardant TPE portfolio with new series launch
Last update on Feb 4, 2026
Avient Corporation, an innovator of materials solutions, announced the expansion of its OnFlex™ NHFR Non-Halogen Flame Retardant thermoplastic elastomers (TPEs) with the NHFR 7001 Series.
Enhanced flame retardancy and mechanical performance
Compared to prior-generation non-halogen OnFlex™ materials from Avient, the new materials in this series provide enhanced flame retardancy for plastic products while also offering customers improved mechanical performance and cost efficiency.
The OnFlex™ NHFR 7001 Series addresses growing regulatory requirements and customer demand for non-halogenated flame-retardant materials. Developed to help manufacturers comply with European Chemical Agency (ECHA) flame retardant guidance, these materials meet UL 94 V-0 performance standards and comply with REACH and RoHS requirements.

Reduce smoke density during combustion
Compared to traditional alternatives such as soft polyvinyl chloride (PVC), the OnFlex™ NHFR 7001 Series offers comparable flexibility while helping maintain mechanical performance over time. In addition, the non-halogenated formulation can help reduce smoke density during combustion compared to conventional soft PVC or halogenated FR TPE solutions. They also can be formulated to incorporate recycled materials, helping customers support their sustainability goals.
“The OnFlex™ NHFR 7001 Series represents our continued response to evolving regulatory requirements and market needs, aligning with our commitment to innovation and sustainability,” said Hermann Fuechter, sr. marketing & product manager EMEA, Specialty Engineered Materials at Avient. “This addition to our portfolio helps customers seeking ECHA-compliant, non-halogenated flame-retardant TPE solutions without compromising performance or cost-effectiveness.”
