Detailed description
A buyer comparing three quotes for the same nominal product is usually comparing three different constructions. This page sets out what is actually in the tape so the quotes can be read side by side.
What the buyer is choosing
The mistake in comparing quotes is looking at the width and the colour and ignoring the yarn. A 25 mm roll at 380 g/m2 and a 25 mm roll at 300 g/m2 look identical in a photograph and behave completely differently after five hundred cycles.
The material question
The fibre is nylon (polyamide). It takes dye deeply, which is why the colour range is wide and why the colour holds through washing at 40 degrees. Its weakness is moisture regain: a nylon roll absorbs water in transit, measures wide on arrival and settles back over about a week, so allow for it in incoming inspection rather than rejecting the lot.
The adhesive version is coated with acrylic rather than hot melt, which is what keeps the bond from creeping when the panel sits in a warm vehicle or behind glass. Full strength takes twenty-four hours at room temperature.
How it is quoted
Minimum order is 500 m in a stock colour and 3,000 m for a custom dye run. The dye minimum is a machine load, not a policy: below it the lot cannot be dyed evenly, and a split lot reads as two colours under D65.
What ships with the goods
Certificates are issued per lot rather than per year, and REACH and RoHS declarations travel with the shipping documents. OEKO-TEX documentation is available on request for skin-contact applications.
Checking it on arrival
Do the peel test on the material you will actually bond to, not on a steel plate. The number in the specification is a reference value measured on steel; on powder coat or on a textile it will read differently, and that difference is the one your customer will notice.
Ask for a sample at your width; it ships in seven days and it settles the substrate, colour and hand questions faster than any specification sheet.
