TPU Corozo Button for Footwear — Specification, Uses and Sourcing Notes
TPU Corozo Button for Footwear: Specification, Uses and Sourcing Notes
TPU Corozo Button is the version buyers specify for footwear when the base material is fixed by performance rather than by price. This entry sets out what the material actually changes, which specification to write into the tech pack, and where the cost sits — the three questions that decide whether the item passes bulk approval.
What it is
TPU gives corozo button its weight-to-strength ratio. In practice that means the trim behaves differently in cutting, in finishing and in wear: shrinkage allowance has to be built into the spec. Buyers who specify the material up front avoid the most common failure — an item that looks right on the sample card and behaves differently in bulk.
