What Our Customers Have to Say

  • – Co-Founder, Medical Device Component Company
    “We've been working with RBP Chemical for over a year now and we've been nothing short of impressed with their product efficacy, technical collaboration, and problem-solving capabilities. Their full suite of de-oxidizing and cleaning chemicals have been a game-changer for our parts and processes, allowing us to achieve the most effective and efficient solution many months faster than we ever could have imagined on our own.”
    – Co-Founder, Medical Device Component Company
  • “RBP has been very helpful in working with our process development team to address the limitations of our current electropolishing process. They helped us explore room temperature electropolishing through a variety of electrolytes. This offers a substantial shift to the growing edge to our process development horizon.”
  • – National Sales Manager, Medical Sales
    “RBP Chemical is a trusted partner in providing application specific chemistries offering real solutions to improve efficiency, sustainability, uniformity impacting through-put by increasing yield and eliminating scrap rates.  Their technical and chemistry team is world-class, true subject matter experts.  It is a pleasure to work with a dynamic industry leader that offers continuous product development with global support.”
    – National Sales Manager, Medical Sales
  • - Director, Research and Development
    “We received exceptional technical support during initial process development. Collaboration with RBP Chemical engineering and technical staff resulted in a highly efficient process.”
    - Director, Research and Development
  • – Director, Engineering
    “We are a Nitinol-based medical device manufacturer and were trying to optimize our deoxidation process by simplifying the chemistry. We use a 3-part solution that is mixed in-house. This inherently creates challenges to have strong process controls in production environment. Dr. Witold and his chemistry team, helped us analyze our components with single solution deoxidation chemistries. In our discussions, the RBP team also debunked a lot of myths and helped us understand the application of our process, much better.”
    – Director, Engineering
