Compounds That Meet NSF International Certification:

Potable water standards written by NSF International and adopted by ANSI (American National Standards Institute) are now the accepted criteria for toxicological review requirements regarding materials in contact with drinkin water. Other accredited laboratories such as Underwriters Laboratores are also testing products per these standards and state legislatures are turing these standards into regulations. In fact, a survey conducted by NSF International in December of 1995 showed that 28 states had legislation in place requiring compliance with ANSI/NSF Standard 60 or 61.

At Minnesota Rubber, we fully recognize the implications that ANSI/NSF standards have on products like yours. That's why we've helped pioneer the research and development of compounds that comply with NSF material certification and listing requirements. Product solutions that respond to both you and your customer's needs now and in the future.

Gain Significant Time And Cost Savings:

Minnesota Rubber's ANSI/NSF Standard 61 certified compounds can help you cut through red tape and reduce certification time. By choosing a Minnesota Rubber compound already certified by NSF International for your assembly, all testing time and costs are minimized. What's more, if our certified compounds are duplicated within a given assembly, further cost and time savings can be realized.

In addition, our ANSI/NSFStandard 61 certified compounds can potentially save you untold dollars in component part testing and registration costs. What's more, consumers can be assured that the components in thier water system will not adversly affect thier water quality.

Material Performance In Hot Water Applications:

All ANSI/NSF Standard 61 Certified Compounds Are Not Created Equal:

Coninual Flow Chloramine Test Results: 30 Days

A Variety Of Certified Compounds To Choose From:

Minnesota Rubber offers the most complete selection of ANSI/NSF Standard 61 certified compounds availible today, with materials approved in 40 to 90 Shore A durometers, in 10-point incriments. (See our technical bulletin.) Most of our compounds are certified for commercial hot water applications - the most stringent of listings - and can withstand prolonged exposure in cold, hot or boiling water.

But that's only the beginning. Minnesota Rubber has also recieved potable water listings to multiple standards, such as BS6920 of the Water Research Council (WRc) in Great Britain and Kautschuk Trink Wasser (KTW) in Germany. We know that export markets are important and we continue to persue agency certifications in other European and Asian Countries. Several NBR compounds have also been certified, whcih will further broaden our range of material offerings and options for you and your customers.

Thermoplastic elastomers (TPE's) are also an NSF certified option for designers in many applications. Minnesota Rubber and QMR Plastics can help you make the right choice in desigining TPE parts into your systems.

Chlorine And Chloramine Resistant Compounds:

Though others within our industry may confuse the issue, chlorine and chloramine are not synonymous. While chlorine performs as a disinfectant in a water supply, it can react with contaminants to form toxic disinfectant by-products (DBP's).

Ammonia is often added to reduce those DPB's, and reacts with chlorine to form chloramine - a chemical relatively harmless to drink, yet destructive to most rubber components.

NSF Certification And Chloramine Resistance Is Our Goal:

Minnesota Rubber has been a leader in the research and development of compounds that resist the eroding effects of chloramines and our EPDM and NBR compounds significantly outperform standard compounds in a chloramine environment.

In addition, our continuous flowing chloramine testing system duplicates the effects of chloramine exposure in field conditions and is superior to the more common static testing.

Our goal is to develop additional compounds offering even greater resistance, and expand our line of ANSI/NSF Standards 61 certified chloramine resistant compounds.

Flow Washers For Water Conservation:

Due to the frequently harsh operating environments for flow washers, proper design and material selection are crtitical. Minnesota Rubber offers a specially formulated EPDM series of water compatible compounds with production quality prototype parts availible for your R&D tests.

As one of our custom molded capabilites we provide production quantities of flow washers, including the frequently requested specification of 2.5 GPM.

As an integral part of our service, our Product Design Group will help design and select the proper material for your flow washer application.
