The future at a glance


AryLite ™ films exhibit superb optical, thermal, mechanical and electrical properties.

AryLite™ films have remarkable thermal stability, exhibit superior thermo-mechanical properties (CTE, tensile strength and modulus) and demonstrate outstanding optical and electrical characteristics.

The combination of these attributes makes these film systems far superior to the alternatives in flexible display applications.
