Silicone Fusible Interlining for Sportswear — Specification, Uses and Sourcing Notes
Silicone Fusible Interlining for Sportswear: Specification, Uses and Sourcing Notes
Silicone Fusible Interlining 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
Silicone gives fusible interlining 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

|---|---|
| Base material | Silicone |

| Related applications | Coats, Down Jackets, Luggage, Yoga Wear |
| Test standard | REACH SVHC Screening |
| Usual packing | 500 pieces per polybag, 10000 per carton |
Properties that matter in buying
- Dimensional stability — 1% allowance is built into the spec before cutting.
- Colour fastness — tested to REACH SVHC Screening on the actual base material, not on a substitute.
- Mechanical performance — cycle life after 20 cycles or washes.
- Compliance — REACH SVHC Screening documentation issued with the shipment.
- Consistency — the approved counter sample becomes the reference for every reorder.
Common uses
- Bedding Sets
- Suits
- Lingerie
- Underwear
- Yoga Wear
- Kidswear
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.
