TPU Reactive Extrusion Industry Reference

Illustration notice. Process illustrations are not verified photographs of this installation.

Industry application reference based on public sources. This is not a Haifeng customer delivery record.

Publicly documented application

The public equipment description identifies linear TPU as a reactive twin-screw extrusion application and includes underwater pelletizing among the downstream equipment offerings.

Planning implications for a new line

For a Haifeng proposal, first distinguish direct one-step feeding from a separate prepolymer/two-step route. Review the multi-component metering interface, reaction equipment, heat removal, melt transfer, water-loop pelletizing and drying. The published example does not establish that all TPU grades require a casting stage before extrusion, or that one reaction arrangement suits every formulation.

Names identifying the end user and contractor are omitted in this summary. Source attribution remains visible. Machine counts, delivery dates, factory location and training/warranty details are left unspecified unless this page expressly reports them from the source.

Reaction feeding, twin-screw reactive extrusion and downstream pelletizing. This describes the public reference architecture, not equipment supplied by Haifeng. The proposed Haifeng configuration is determined separately from the production brief.
