When lamination protection or precision electronics fastening calls for heat resistance, a thin profile and a clear view of the workpiece, transparent PET tape brings those needs into one roll. The official page lists 180°C heat resistance, a 50 ± 2 μm total thickness and a transparent PET backing. For engineers and buyers, the practical benefit is less visual obstruction and less stack-up burden while retaining a tape intended for thermal-process protection. The 180°C figure is a published heat-resistance condition, not a service-life guarantee for every process.

A thin, transparent layer keeps alignment visible

The clear roll leaves the covered area visible, supporting precision alignment and visual inspection. The transparent PET tape product page specifies a 0.038 mm PET backing plus a 0.012 mm adhesive layer, for a total thickness of 50 ± 2 μm. That verified profile gives designers a starting point for assessing stack height and masking coverage.

180°C heat resistance supports lamination protection

The product page lists heat resistance at 180°C and names hot-press or lamination-process protection among its uses. This makes the tape relevant where a short high-temperature process is followed by removal. Selection should still include peak and dwell temperatures, the bonded surface and the load direction; a single temperature number cannot represent the complete thermal history.

Initial tack and removal data support production handling

The official inspection table records initial tack at ball No. 18 and a passing fast- and slow-peel adhesion test; the product description also identifies clean removal as a feature. These data support quick positioning and post-process removal as intended use directions. Actual residue can still depend on surface cleanliness, thermal history, lamination pressure and dwell time, so testing on the production substrate remains necessary.

Why high temperature must be paired with time

NIST presents the Arrhenius temperature-acceleration model as t_f = A × exp(ΔH / (k × T)). Here t_f is time to failure, A is a scale constant, ΔH is activation energy for the governing failure mechanism in eV, k is Boltzmann's constant at 8.617 × 10^-5 eV/K, and T is absolute temperature in K. This temperature acceleration model explains why exposure time belongs beside temperature in a thermal review. It applies only when one thermally activated mechanism governs within the evaluated range. Without product-specific aging data, it cannot predict this tape's life or allowable dwell time.

Bring the process conditions into sample evaluation

For a specification review or sample request, provide peak and continuous temperatures, heating cycle, bonded surface, dimensions, visibility requirement and removal timing. Compare those conditions with the official 50 μm transparent PET tape specification, then test initial tack, peel and residue on the actual substrate. Lixing provides sample and specification consultation; the website does not offer online checkout.
