Medical Compounding

Lifesaving and life extending technologies are evolving around the world.  The base materials used in the production of such devices are often overlooked and taken for granted despite being the backbone of the technology.  Many times, engineering decisions are made based on previous personal history with any given material be it Nylon or PTFE or HDPE.  The limitations of the base materials are often understood but the ability to customize those properties is not.  On many occasions project teams choose previously used, well-known materials, however via a short conversation with Compounding Solutions your eyes can be opened up to so much more!  Tens of thousands of unique materials exist, each of which can be compounded to modify its properties.  Hard or soft, compliant or rigid, clear or colored, lubricious or tacky qualities can all be imparted via a huge range of additives.

A quality that nearly all device companies search for is a USP VI or ISO 10993 certification on the materials.  Generally, this approach is followed because it is thought that this will lead to an FDA approval based on that rating.  Anything but that is the case.  FDA device review is done as an agglomeration rather than piecemeal.  While the constituents may be USP VI the entire device is not.  An overloading within the assembly of any given component can push cytotoxicity levels over acceptable limits.

Compounding Solutions stays very close to the medical device industry working with our customers from the R&D process through the final FDA reviews and market launch.  Throughout this process, we focus on the feedback the reviewers are passing along.  With this knowledge, we can help guide you to select the most appropriate components for your custom compound.

Compounding Solution’s compounding process is done in our controlled environment production area (White room) which ensures that all our medical grade polymers and compounds will be made with the highest quality and purity in mind.  It is designed to minimize exposure to airborne particulates, common contaminates, and moisture.  Beginning in October 2011, manufacturing of our medical grade compounds was transferred to our “White Room” compounding area.  Responding to the needs of our customers as well as industry demands for cleaner manufacturing environments, we set out to complete a massive facility expansion centered on a new manufacturing area meeting the needs of the medical compounding market.

Our “White Room” is the largest production facility of its kind.  To ensure a clean environment, the “White Room” includes an Air Lock with a positive pressure environment, sealed and polished concrete floors, HEPA filtered air exchange with humidity and temperature controls, and epoxy coated wall surfaces to repel dust and allow for easy cleaning of all surfaces.  Great care was taken in designing our “White Room” to minimize all potential sources of product contamination.  From point of use dust collectors, to underground energy sources, we have ensured that every compound manufactured in our “White Room” will be of the highest quality and purity.

Toll Compounding

Compounding Solutions offers toll compounding services that allow our customers to supply the raw materials and specify formulas. We then supply the compounding experience and knowledge to ensure the same top-notch quality that we expect all of our own products to have. Your toll compounding products are treated with the same care and are subjected to the same rigorous quality testing as our own custom compounded products.

Our equipment allows for maximum quality and consistency from lot to lot and pellet to pellet with the use of:

> Dehumidifying dryers.
> Nitrogen blanketed loss in weight feeders for both pellet and powder.
> Strand or underwater pelletization to allow for the best pellet quality based on the material being compounded.
> Tumblers allow for post-blending to achieve consistent final product prior to packaging and shipping.

Our compound testing capabilities include melt flow, viscosity, density, ash content, hardness (shore A or shore D), tensile, elongation, along with a multitude of others.

Color Matching

Work with our team of color experts today to achieve the desired color for your device!

Our team has a lengthy reputation for providing accurate colormatches for a wide range of medical device applications. From existing parts to the Pantone Matching System, color concentrates to
pre-colored compounds, our team of experts develops custom formulations that provide consistency and compliance.

Color selection in the product design process is often decided by the marketing team but it is a key part for the design, especially within the medical device industry. In recent years, the FDA has imposed more strict standards and approvals on colorants used in medical devices, which can also limit the final color options available for medical devices depending on final end use.

In the medical device industry, colorants fall into two main areas of FDA approvals. Colorants approved under FDA 21 CFR 173-178 are considered to be “Food Grade”. The FDA has moved, in recent years, to expand the 21 CFR 73 Subpart D listings to include any device that has blood or body fluid contact. This list of colorants for use in medical devices are exempt from batch certification. The selection of initial pigments can greatly impact the FDA approval process for medical devices. Without proper selection rejection of the device is possible

Contact us today to discuss your desired color and help ensure a smooth FDA approval process.

Dry Blending

Compounding Solutions can provide anything from highly technical compounding needs to very basic homogenization of your existing pelletized resins and powders. This can be done in quantities as little as one pound or scale up to truck loads as needed via ribbon or tumble blending. As a simple example the blending of High Density Polyethylene and Low Density Polyethylene to create a Medium Density Polyethylene can be done in a dry blending method simply by effective drum mixing. Many organization do this by tumbling materials in a plastic bag or in any bin available for on demand needs. Our team has taken a more science based approach and removed the human element to ensure consistency.

Through the years, we have used several different effective methods however we have conducted validation trials to confirm the best methods. Based on quantities and materials types we have paths for the most effective homogenization. Experimenting with a range of bin sizes and fill levels we have found that adjusting these parameters will provide the best distribution possible for your needs. Overfilling the bins will create problems as will underfilling. A balance of both fill level and time in agitation provide consistency.
