UPILEX®-NVT UPILEX®-VT

This formulation is unique to UBE and exhibits outstanding dimensional stability, low water absorption and very high chemical resistance.

Super-heat resistant polyimide film produced from UBE’s exclusive “BPDA (Biphenyl tetracarboxylic dianhydride)“ monomers.

“UPILEX®-VT” and ”UPILEX®-NVT” are heat bonding polyimide films having heat fusing layers on both side of the film, created by the polyimide resin equivalent of “UPILEX®-S”.

High quality flflexible circuits without an adhesive layer are obtained, by heating and pressing “UPILEX®-VT” or ”UPILEX®-NVT” with metal (Cu, SUS, Al) foil.

In addition, they are also available for bonding films comprised of metal, ceramic and other materials.

●Flexible circuits without adhesive are produced.

●This offers high tensile strength and tear strength.

●Offering the same low water absorption, low dimensional change and high heat resistance as “UPILEX®-S”, with the addition of laminate workability in the heat press.
