Detailed description
If the last shipment had edges fraying, a width that measured wide on arrival, or a peel that read low in incoming inspection, the cause is almost always in one of the four items described on this page rather than in the price.
What the buyer is choosing
Colour is a specification, not a preference. Dyed lots are matched to a retained standard under D65 light, and a black that matches in an office can read green in daylight. If the colour is customer-facing, approve a physical swatch and keep it, because a photograph is not a standard.
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.
If the grade is still open, send the application and the cycle count and we will tell you which of the three constructions is the cheapest one that will survive it.
