Zinc Alloy Rubber Patch — Specification, Uses and Sourcing Notes
Zinc Alloy Rubber Patch: Specification, Uses and Sourcing Notes
Zinc Alloy Rubber Patch is the version buyers specify 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
Zinc Alloy gives rubber patch its weight-to-strength ratio. In practice that means the trim behaves differently in cutting, in finishing and in wear: plating and coating adhesion must be tested on the actual base. 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.
Typical specification
| Item | Rubber Patch |
|---|---|
| Base material | Zinc Alloy |
| Standard size | 3# Gauge |
| Common finishes | Antique Brass Plating, Anodised Finish, Matte Black Coating |
| Processes | Enamel Filling, Ultrasonic Welding, Weaving |
| Typical applications | Bedding Sets, Upholstery, Bags, Shirts |
| Test standard | RoHS |
| Usual packing | 100 pieces per polybag, 2000 per carton |
Properties that matter in buying
- Dimensional stability — 2% allowance is built into the spec before cutting.
- Colour fastness — tested to RoHS on the actual base material, not on a substitute.
- Mechanical performance — cycle life after 50 cycles or washes.
- Compliance — RoHS documentation issued with the shipment.
- Consistency — the approved counter sample becomes the reference for every reorder.
Common uses
- Hats
- Swimwear
- Underwear
- Scarves
- Bags
- Sportswear
How to specify it
- Name the base material in the tech pack, not just the item.
- Fix the size and tolerance in writing before sampling starts.
- Approve a counter sample made from the actual bulk base material.
- Order the test report against the standard your market requires.
- Retain a golden sample at the factory and a second one with you.
