Zirconia Film

Zirconia Film

Zirconia Film

Zirconia film developed by Orbray is 20µm thick. It has excellent flexibility characteristics and an extremely smooth surface.

Zirconia has excellent heat resistance, corrosion resistance, strength, wear resistance, and fracture toughness characteristics. Applying its ultra-thin polishing technology, Orbray has created flexible zirconia ceramics, with a surface roughness (Ra) of < 5 nm.

Orbray's flexible zirconia film can be custom-made to meet your specific product development requirements. Please inquire by contacting us directly.
