Properties
The unique APS process
actually enhances the mechanical properties of the biomedical implant.
Our exclusive method yields a 25% reduction in fatigue properties, resulting
in the groundbreaking ability to render the entire surface area of the
revision product a bonding surface without breakage. The Shear and Tensile
strengths for all biomedical coatings meet FDA guidance documents.
