Non-Yellowing Spec Request Builder
Turn “it won’t yellow” into a testable purchase-order clause. Fill the four gates below; the tool writes an acceptance condition you can send to any aliphatic TPU film supplier — Tengyang included.
Configuration Gates
(name the cycle; “tested to G155” alone is unfalsifiable — the standard has 14)
(hours)
(ΔYI, ASTM E313)
(a YI without this pair is not reproducible)
a bare film can pass while the laminate fails
(ASTM D1003, if the part is seen through)
Acceptance Clause Output
Fill the gates above and press “Generate Clause”.
Important: This clause commits the threshold before the specimens go into the chamber, which is the whole point — a pass mark chosen after the data arrives is not a pass mark. Send it to three suppliers and compare what comes back.
