From waste plastic to finished filament

Molecular reorganization · Performance upgrading · Higher-value applications

  1. 01

    Waste feedstock

    Identify and qualify

    PET, PC, PBT, PLA and other suitable feedstocks enter the process after source assessment, compatibility screening and necessary pretreatment.

  2. 02

    Molecular reorganization

    Reactor conversion

    Molecular exchange, chain rearrangement and applicable cyclization reactions regulate polymer composition and chain structure.

  3. 03

    Compounding

    Formulation and performance

    Multicomponent blending, compatibilization and functional additives are combined with vacuum devolatilization and filtration.

  4. 04

    Filament production

    Continuous process control

    Precision extrusion, cooling, diameter measurement, drawing and winding convert materials into printing filament.

  5. 05

    Finished filament

    Validate and deliver

    Diameter, mechanical properties and print performance are evaluated, with formulation and color customization for specific applications.

Ranges are drawn from the supplied process schematic. Conditions depend on feedstock and product system; they are not a universal recipe for all mixed plastic waste. Diameters such as 1.75 / 2.85 / 3.00 mm must be confirmed against equipment and order requirements.

Stiffness in elastic deformation

Values are reproduced from the supplied comparison chart for representative PolyChainer circular-filament and comparison-product samples. Increases are calculated as (PolyChainer − comparison) / comparison and rounded. Test conditions are subject to the corresponding test reports; results do not cover every grade or batch. Elongation at break is not impact strength. A circular feedstock route does not imply that all products are biodegradable.
