Model 501 defines a regular 0.015 mm foil and 0.042 mm nominal total-thickness construction.

Model 501 is the lowest-total-thickness construction in Lead Top’s current standard range. It combines 15 μm aluminum foil with a nominal total tape thickness of 42 μm, excluding the release liner.
* Nominal total thickness excludes release paper or release film.
Most buyers can select an established model and complete the order using our regular adhesive, liner and roll-format options. Special development is available only when the standard range does not cover the requirement.

Water-based and solvent-based acrylic systems are regular production options selected according to the bonding surface and service requirement.
Release paper is the standard liner. Release film is used only for selected requirements.
The applicable temperature range is confirmed after the acrylic adhesive system and complete tape construction have been selected.
Widths, roll lengths, cores and packaging can be supplied to suit purchasing and production requirements.
