The first filled polypropylene (PP) resin, “ISOFIL H 20 TP F HS BK”, developed by Sirmax for applications in the automotive sector and in electrical and electronic equipment (EEE), has been approved by RecyClass as fully compatible with existing recycling streams in Europe. According to the source material, this decision is intended as a significant step toward increasing circularity for plastic components in these market segments. The technology approval concerns a material that can be recovered and reprocessed without negative effects on the overall quality of the resulting recyclates.
The assessment was performed in line with the RecyClass Recyclability Evaluation Protocol for Automotive & EEE Resins. Testing confirmed the resin’s compatibility with industrial recycling processes for filled PP materials used in Europe, meaning the material can be effectively recovered and reprocessed within existing infrastructure. The source highlights that the evaluation found no negative impact on the final quality of recyclates produced in these processes.
The positive evaluation of “ISOFIL H 20 TP F HS BK” has enabled its inclusion among the control materials used in the recyclability evaluation protocol for filled PP plastic components. According to the source, this is intended to strengthen the robustness and repeatability of testing and to provide a scientific basis for assessing complex plastic parts. In practice, this may support the design of automotive and EEE components for compatibility with recycling systems that are already in operation.
Material characteristics and application examples
“ISOFIL H 20 TP F HS BK” is described as a black polypropylene resin filled with 20% talc and heat-stabilised to meet performance requirements in durable applications. Materials of this type are widely used in automotive exterior parts such as wheel arch liners and mirror housings, as well as in interior components including pillar trims and door panels. In the EEE sector, similar resins are used in large household appliances such as washing machines and dishwashers for internal structural parts, and in smaller appliances such as vacuum cleaner bases or internal mounts in coffee machines.
Regulatory context and the role of recyclability assessments
The source indicates that reliable and harmonised recyclability assessments will play an important role in meeting requirements stemming from upcoming European legislation, including the End-of-Life Vehicles Regulation and the planned revision of the Waste Electrical and Electronic Equipment Directive. According to the source content, by supporting the development of closed-loop recycling systems, RecyClass is intended to contribute to the transition toward a circular economy for plastics in automotive and EEE applications.
