MELINEX® ST506

Product Description
MELINEX® ST506 is a crystal clear, high gloss, heat stabilized polyester film. It is pretreated on both sides for improved adhesion. It can be overprinted with a wide range of solvent-based graphic inks and varnishes, silver conductive and dielectric inks. It is ideally suited for graphic and certain circuitry layers in membrane touch switches.

Our process of continual improvement in quality and specification now enables us to provide the following properties and benefits:

* Heat stabilized to give excellent dimensional stability at temperatures up to 302℉.
* Excellent adhesion to a wide range of solvent based inks, graphics inks and varnishes, silver conductive inks and dielectrics.
* Excellent durability and toughness giving long lasting switches, particularly when compared with polycarbonate.
* Greatly superior solvent resistance to polycarbonate, making MELINEX® ST506 particularly suitable for use in many industrial applications.
