Review the archived FLEXcon Classics Plus 41006 sheet for white vinyl construction, converting guidance, test values, and a thickness discrepancy to confirm. This resource is for manufacturers evaluating custom nameplates, labels, overlays, or related identification components. Use it to prepare your project questions, then talk with our team about the requirements that apply to your part.
The archived FLEXcon Classics Plus 41006 PDF describes a semi-flexible white vinyl pressure-sensitive stock for labels, decals, and nameplates. It also contains a detail that prevents the file from serving as a current specification: page one calls the film 4.0 mil, while page two lists a 3.5-mil film value with a plus-or-minus 10% range.
That conflict should remain visible, not be silently “corrected.” The two-page sheet has no explicit issue date, and a current supplier document is needed to establish the actual construction. Until then, the archive can guide questions about appearance, converting, ink, adhesive, and testing without authorizing a purchase description.
The product-description paragraph says “4.0 mil” white vinyl. The physical-properties table says film thickness is 3.5 mil, or 89 microns, plus or minus 10%. Both statements appear in the same archived file. The footer form code does not explain which one controls.
A current request should ask for the latest revision, product construction, tolerance, and ordering identity in writing. Do not average the values or select the one that better fits a design. Finished thickness can affect handling, conformability, edge profile, and how a custom decal sits against its surface.
For the permanent acrylic layer, the data page uses 25-28 microns (1.0-1.1 mil) and separately notes 0.1 mil of variation. Its two-side polycoated layflat liner is recorded as 175 microns, equivalent to 6.9 mil, with a 10% plus-or-minus range.
The sheet also attributes lower shrinkage to a lower plasticizer level. That is a supplier description of the historical stock, not a guarantee about another vinyl or the behavior of a finished printed construction.
FLEXcon says the film retains some conformability for curved surfaces. “Curved” can mean a large cylinder, a tight radius, a compound contour, or a surface interrupted by a seam. Those conditions create different strain and edge-lift questions.
Record the radius, direction of curvature, label orientation, application method, and whether the film must bridge texture or a recess. A control panel overlay can add windows and key areas that further change the stress pattern. Evaluate a converted sample on the intended geometry rather than relying on the adjective semi-flexible.
The first page says the face was compatible with most standard non-vinyl-based screen-process and offset inks. It also tells users to test ink adhesion with their specific ink chemistry. A current screen-printing trial should use the proposed ink, cure, artwork coverage, and production sequence.
Include any clear coat or laminate in the sample. Examine ink adhesion, color, gloss, blocking, flexibility, and cut-edge behavior. Passing the print portion does not prove that the pressure-sensitive adhesive works on the mounting substrate.
An opaque white face can isolate graphics from the equipment color, but the approved white point and gloss still need a physical reference. Review whether underlying texture or dark edges remain visible, especially where the part crosses a recess or curve.
Define cosmetic acceptance zones before production. Small specks, liner impressions, surface marks, and edge distortion may be evaluated differently in a logo field than beneath dense print. The inspection plan should state finished viewing distance and lighting rather than relying on an unlimited magnified review.
The supplier sheet refers to sheet printing, die cutting, guillotine cutting, hand dispensing, and hand application. It says the adhesive did not tend to ooze and the moisture-resistant liner resisted curl. Those statements can help identify what to observe during a trial.
For the actual job, verify sheet flatness, feed, adhesive buildup, cut depth, liner scoring, waste removal, stacking, and hand peel. Finished geometry may require die or digital cutting, and multiple coordinated versions may benefit from controlled label sets. Neither choice should be inferred from the material sheet alone.
Under ASTM D896, the archived table rates basic cleaners and water as good, gasoline as fair, and toluene as poor. These are not interchangeable terms, and the poor toluene result should not be lost inside a broad chemical-resistance claim.
Ask what fluid will actually contact the part, at what concentration, for how long, and with what recovery or wiping action. Test the printed and protected construction, because ink and overlaminate can respond differently from the base stock. If the decal carries customer-approved caution content, compare the information role with warning-label options without treating the material data as proof of safety performance.
The sheet lists average peel values of 63 ounces per inch on stainless steel, 70 on acrylic, and 68 on glass under a modified ASTM D903 method after 72 hours. Expected shear is 20 hours under the stated ASTM D3654 setup, while tack is 370 grams per square centimeter under ASTM D2979.
These figures are not a ranking of all possible surfaces. Coatings, additives, roughness, cleaning, pressure, dwell, and temperature can alter the result. U.S. Nameplate’s adhesive information illustrates the broader point: product identity and test conditions must travel with every number.
Application is assigned a 50 F minimum in the old table. The same section places service between -40 F and 176 F, states two years for exterior life, and describes two-year storage under 70 F/50% relative humidity. According to the supplier footer, those typical values are guidance and do not form a warranty.
Current acceptance criteria should reflect the assembled part, not a copied field. Document sunlight, heat cycling, cleaning, abrasion, flexing, edge exposure, and the customer’s replacement plan, then select tests that represent those conditions.
The first page says 41006 was UL-recognized for indoor and outdoor use with occasional water or lubricating-oil exposure and cites file MH10170 (N). Because the PDF is undated and the film gauge conflicts internally, the statement cannot establish current recognition.
A recognition-dependent project needs the current file, authorized construction, printing system, substrate, temperature range, and end-use conditions reviewed together. The Quality Standards page provides company context but does not replace that product-level verification.
Send those controlled requirements through the request consultation form. The most responsible use of the 41006 archive is to expose what needs confirmation, especially the one specification the document itself leaves unresolved.
When clarification arrives, record the supplier revision and the resolved thickness beside the approval sample. That closes the discrepancy for the current job without altering the historical PDF or implying that the answer applies to every prior or future version.
