Our expertise lies with developing materials for very demanding and highly specialized applications. Over the years, we have developed more than 1,400 active rubber compounds and mold over 300 plastic compounds, each designed to meet a unique need whether it's
an erosive environment or temperature extreme. Our certification includes UL and FDA approved materials and ANSI/NSF certified compounds. We provide the plumbing industry with the largest selection of chlorine and chloramine resistant compounds.
 
Both Minnesota Rubber and QMR Plastics have earned a
solid reputation for high quality components. Consistent quality and on time delivery performance have earned quality awards from companies such as Caterpillar, John Deere, Allied TBS, Eaton, and SHURflo. Each of our manufacturing facilities is QS-9000 certified with an on site materials lab to ensure consistent quality for all custom engineered compounds. Material characteristics such as mechanical properties, rheology, dispersion and hardness are rigidly controlled.
