Super-heat resistant polyimide film produced from UBE’s exclusive “BPDA (Biphenyl tetracarboxylic dianhydride)“ monomers.
This formulation is unique to UBE and exhibits outstanding dimensional stability, low water absorption and very high chemical resistance.
In addition to the excellent properties of general polyimide resins (heat resistance, high mechanical properties and excellent electrical insulating properties), UBE’s polyimide film “UPILEX®” has various advantages unique to our formulation.
●High heat resistance--- “UPILEX®-S” can be used in high-temperature processes just below 500°C. This exceeds industry standard operating temperatures around 300°C.
●High mechanical properties--- Upilex has excellent wear resistance and toughness. This allows use of thinner films in applications where strength is critical.
●Chemical resistance--- It has excellent chemical resistance to organic solvents, gasoline, automotive oil, alkalis, acids etc..
●High-performance technology--- The industry leading surface uniformity and smoothness of “UPILEX®” improves performance and adds value to your application.
