Minnesota Rubber and Plastics (MR&P) announced the design and installation of an advanced custom rubber compound mixing laboratory and testing capabilities to serve all of the MR&P rubber molding facilities. As a contract manufacturer of FDA Class 1, 2 and 3 products, MR&P provides a unique science-based approach making it a preferred manufacturing partner for industry leaders in North America, Europe and Asia.


MR&P’s new laboratory and testing facilities include an automated rubber process analyzer. This system is the latest dynamic mechanical rheological test instrument designed to measure the properties of polymer and rubber compounds before, during and after the cure. Up to 100 different compound samples can be tested quickly without operator intervention. When required by customers, this allows for 24/7 testing which is very important to MR&P global molding operations.

The new MR&P system has many additional advantages over traditional rubber test methods because of its ability to test under conditions of variable strain frequency and temperature, which reveal important differences in rheological, rheometric and dynamic viscoelastic properties.

The versatility of this system allows for polymers and components to be comprehensively characterized, especially in terms of intrinsic material properties, processability characteristics, and end product performance. MR&P works with over 3,000 different compounds to meet a wide variety of customer requirements. The mission of the new facilities is to ensure that every elastomer formulation developed by the MR&P design and research teams is mixed correctly and that batch consistency is strictly maintained to guarantee the highest quality products at all manufacturing facilities. preferred manufacturing partner for industry leaders in North America, Europe and Asia.

MR&P molds and assembles medical devices requiring high tolerance components that facilitate device function. Device designs include seals that isolate fluids and gases, internal bosses for aligning actuating mechanisms containing seals and springs, and snap-fit designs that lock the assembly together without the use of adhesives. It produces needle-free injection devices, surgical instruments, diagnostic instruments, valves, pumps, connectors, diaphragms, plunger tips, seals, laboratory equipment and disposables, among other devices.

MR&P’s corporate-wide quality systems include: ISO 13485, ISO-TS 16949, and ISO 9000 in all facilities. These facilities operate under a corporate-wide Environmental Management System registered to the International Standards Organization series ISO-14001.

MR&P has over 65 years experience serving the medical device industry and understands the importance of controlling processes to ensure product validation. Within this discipline is MR&P’s fundamental goal of providing quality products on time, on budget and in compliance.
