L0509J - Yellow polyester tape with thermosetting acrylic adhesive

A yellow polyester tape designed for demanding electrical applications

TheL0509Jis a single-sided adhesive tape made of yellow polyester film with a thermosetting acrylic adhesive. It has been specially developed for electrical and electronic applications where dielectric strength, thermal stability, and chemical resistance are essential. Thanks to its thin yet robust structure, it provides a reliable solution for insulation, winding, and protection operations in technical industrial environments.

Its yellow colour facilitates visual identification on components, which is a practical advantage during application, quality control, or identification of isolated areas. It thus integrates perfectly into electrical manufacturing, technical maintenance, or industrial processing environments.

A solution suitable for winding and insulation

TheL0509Jis particularly intended for insulation applications of motors, transformers, and winding systems. Its good dielectric strength and thermal classB up to 160°Callow it to meet the requirements of electrical environments subjected to heat, mechanical stress, and certain chemical agents.

Its polyester backing also ensures good resistance to abrasion and cuts, which improves the reliability of the tape in applications where it may be exposed to friction, repeated handling, or assembly stresses.

A technical tape for industrial environments
