When adding an extruded polymer to a substrate, as a part of the extrusion process, the coating of this polymer is done directly from the diehead onto the substrate. The substrate can be a wide variety of materials such as paper, paper board, PE or PP film, aluminium foil, woven fabric and carpets.

Carpet backing coating
When looking to meet your customer demands for a carpet which is not only custom-made but also sustainable and recyclable, the MEAF extrusion lines for thermoplastic elastomers (TPE), thermoplastic olefins (TPO), thermoplastic rubber (TPR) and thermoplastic urethane (TPU) are the answer to your desires.

Our extrusion lines are optimised to work with a variety of materials (even with lower melt temperatures such as PVB and PB1) and are optimised to extrude the thermoplastic directly onto the carpet. In addition to the extrusion, we can also accommodate the integration of a fleece as secondary backing, coating/lamination of the backing with other polymers such as PP or PE and/or filling with high concentrations (≥ 60%) of the backing with a mineral such as CaCo3. (calcium carbonate or talcum).

Extrusion coating lines key advantages:

  • Increased output with smaller sized extruders.

    Improved by 20% – 100%

  • Increased energy efficiency

    By 10 – 65 % per kilogram of produced product

  • Optimal processing with regrind/recycled material

    Up to 100% regrind

  • Stable pressure at higher outputs

    Minimal flow and pressure fluctuations

  • Multiple materials with same screw and barrel design

    No need to change the screw when changing the raw material

  • Reduced polymer degradation

    Low friction extruder ( less than 300 RPM – even at higher outputs) which results in less material degradation.

  • Integration of MEAF sheet extrusion line with other coating equipment
