Brass Plastic Zipper for Sportswear — Specification, Uses and Sourcing Notes
Brass Plastic Zipper for Sportswear: Specification, Uses and Sourcing Notes
Brass Plastic Zipper is the version buyers specify for sportswear 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
Brass gives plastic zipper its strength and surface character. 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.

Properties that matter in buying

- Mechanical performance — abrasion resistance after 50 cycles or washes.
- Compliance — California Prop 65 documentation issued with the shipment.
- Consistency — the approved counter sample becomes the reference for every reorder.

How to specify it
- Name the base material in the tech pack, not just the item.

- Retain a golden sample at the factory and a second one with you.
