Nickel Titanium, better known as Nitinol, is a biocompatible metal alloy often used in catheters, stents, and other medical devices.

Nitinol requires specific chemical solutions to ensure effectiveness and decrease the risk of rejection. RBP Chemical Technology is the leader in development, manufacturing and the distribution of specialty chemical processes for the cleaning and passivation of Nitinol and other alloys used for implanted medical devices.

Our products are designed to:

1

Clean

To remove surface residues and assure uniform etching & polishing. Non-aggressive, effective on post-processing soils.

Solutions:

2

Deoxidize & Etch

To remove oxides with controlled removal and polishing of base metal. A variety of deoxidizers for a variety of substrates and situations.

Solutions:

3

ElectroPolish

To obtain a polished surface. Includes Unique room temperature electropolishes (no cooling necessary).

Solutions:

4

Passivate

To build a protective oxide layer for increased biocompatibility. Nitric or citric acid based chemistries are commonly used.

Solutions for cleaning, deoxidizing and polishing medical implant devices.
