Brand Tape Cross-Reference: Matching a tesa, 3M or Sekisui Grade You Already Use
You already have a grade number on a drawing or in an ERP item. This page explains what we do with it: identify the construction, quote either the original material or a construction from our own range, and prove the match on your surfaces before anything changes in your approval file.
No published equivalence claimsOriginal grade or our constructionTested on your substrateRoute stated in every quotation
Our position
Why this page does not give you a one-to-one replacement column
A brand code describes a manufactured construction and the process behind it. The datasheet belongs to the manufacturer, and the performance it describes is only reproducible under the conditions that manufacturer tested. Publishing a table that says "our tape equals their grade" would move the risk from the paper to your production line.
So the cross-reference work happens in the open, in four visible parts: what the reference is, what your joint needs, which route we quote, and what was tested. Every quotation names the brand, the grade, the construction and any converting step we add, so your approval file and your batch documents describe the same material.
Route chosen
Original brand grade, our own construction, or the original material converted here.
Sample tested
Tested on your substrate, your cleaning method and your test standard, not on a catalogue.
Result recorded
A passed match is added to the grade library with its date and tested construction.
Method
How a grade match is actually carried out
Five steps, in this order. Skipping the first two is where a substitution normally fails.
Read the reference you hold
We start from the datasheet, the part you are buying or the print that calls the grade. Carrier type, adhesive chemistry, thickness, liner and the manufacturer code are recorded before anything is proposed. Nothing is matched from the brand name alone.
Match the construction, not the number
A grade number tells us the manufacturer, not the joint. We look at the bond line, the two substrates, the temperature profile, whether the bond must hold in shear or resist peel, and whether the tape stays in the product or is removed after a process.
Choose the route
Three routes are possible: supply the original brand grade through our channel, supply a construction from our own range, or supply the original material and convert it here. We state which route a quotation uses so your approval file is accurate.
Test on your surfaces
Samples are supplied for your own substrate, your own cleaning method and your own process. A cross-reference without a test on the real surface is a guess, so we ask for the test standard you have to meet and the failure mode you cannot accept.
Record the result in the grade library
When a match passes your validation it is added to the grade library with the date, the tested construction and the report reference. Entries that have not been tested stay marked as untested, so nobody reads a possibility as a result.
Our range
What each of our families is used for, and how a reference is handled
The families are ours, so the descriptions are ours. The reference handling column tells you what we ask for before a grade is proposed.
| Our family | Where it is used | How a branded reference is handled |
|---|---|---|
| Double-Sided Tape | Thin bond lines on displays, FPCs, battery modules, nameplates and trim, where a carrier or transfer adhesive is specified. | Buyers usually arrive with a tesa or 3M double-sided code. We identify the carrier, adhesive chemistry and thickness from your datasheet, then quote the original grade or a construction from our range. |
| Foam Tape | Panel, trim, frame, glazing and sign bonding where gap, texture and outdoor exposure rule out a thin tape. | Commonly referenced as an acrylic foam or VHB-style grade. We confirm foam core, thickness and skin, then test on your coated surface before recommending a substitution. |
| Functional Tape | Insulation, protection, grounding, flame-retardant and heat-resisting roles in electronics, battery and automotive builds. | These are the grades where a number carries the most meaning. We work from the property you need (dielectric, temperature, flammability, release behaviour) and match against documented data, not a catalogue name. |
| Masking & Packaging Tape | Paint, plating and anodising masking, clean removal windows, carton sealing and bundling. | Masking grades fail by residue or bleed, not by adhesion. We match the bake window and the coating system, and confirm removal behaviour on your line. |
| Die-Cut Parts | Ready-to-install pieces cut from any of the above, on the liner and presentation your line or applicator needs. | A converted part is matched by drawing and process, so the reference grade matters less than the tolerance, the kiss-cut depth and the liner release after ageing. |
| Specialty Tape | Medical, IVD, laboratory, high-temperature and low-VOC constructions with restricted material requirements. | Specialty grades need document review before any trial. We confirm the material claim you have to support and what evidence we can provide for the supplied grade. |
Product family pages carry the constructions, thickness ranges and documents available for each family.

Supply and authorization scopeSend these six things with a cross-reference request
With all six we can usually name a route and a test plan in the first reply. With only a grade number we can still start, but the first reply will be a question.
- The brand and grade code you use, or the datasheet page
- The two surfaces being bonded, including coating or plating
- Bond area, gap and whether the joint sees shear, peel or impact
- Temperature, humidity, UV and chemical exposure in service
- Whether the tape remains in the product or is removed after processing
- The test you must pass and the annual volume
Cross-reference questions
Do you have an equivalent to tesa 68666?
We work from the datasheet for the code you hold, then quote either the original tesa grade through our channel or a construction from our own range. A published equivalence claim is not something we make without a test on your surfaces.
Can you supply a 3M VHB alternative?
Yes, as a proposal rather than a catalogue claim. We match foam core, thickness and skin against your gap, surface energy and load case, send samples, and record the result only after your validation on the real substrate.
Why does your cross-reference table not give one-to-one replacements?
Because a brand code describes a manufactured construction, and the datasheet behind it belongs to that manufacturer. Matching on a number alone transfers the risk to you. We match the joint and put the evidence in the quotation.
Can you supply the original brand grade instead of an alternative?
Often yes. tesa is supplied through our authorized channel, 3M and Sekisui through qualified channels. The quotation states the grade, the channel and any converting step we add, so your approval file stays accurate.
Do you convert branded material into die-cut parts?
Yes. Where the construction allows flat-bed, rotary or laser cutting we convert it in our Shenzhen plant, and the quotation says which material was used and what was added.
How long does a grade match take?
The review is quick once we have the datasheet and the application. The timeline that matters is your validation: substrate preparation, bonding, dwell and your own test standard. We propose the sequence when we send samples.
What happens when a grade is discontinued?
We identify the construction from the last datasheet or a retained sample, propose the closest route, and give you a documented comparison your customer can review before approval changes.
Is Chinese tape lower quality than brand tape?
Original-brand tape is consistent because its process is controlled end to end. A converter earns its place on selection, die cutting and delivery, not by pretending to be the brand. We say which route a quotation uses.
Send the grade code and the datasheet page.
We tell you which route the quotation uses and what has to be tested before your approval changes.
