1 mil Electrical grade Polyimide with pre-cured pressure sensitive silicone adhesive film is designed to operate at elevated temperatures higher than polyester. This heat-stabilized film surpasses the dimensional stability of polyester, and will thermoset to increase adhesion values.

It can be used for electrical insulation, safety, and plating even at parts that are over 200º C
Especially places that are restricted to use lead are substituting to this product for protection while processing SMT reflow. PCB line, LCD, Soldering.
