Identifying Safe Materials for Consumer Products

07/20/2009 10:11 PM

Hi Guys,

Need some help identifying if certain materials are safe for exposure to drinking water.

Specifically rubbers/silicones/thermoplastics (elastomers). Roughly shore A 30-40 duro. Haven't been able to find a good resource that simply lists the names of the materials that are considered food safe (fda approved?). What regulatory requirements are involved in products like this?

Trying to develop a concept and want to make sure it is a safe as possible for humans and pets. The materials exposure would be incidental to the potable water but some run off back into the supply would occur. The material would also be in a constant state of slight to moderate tension.

Thanks for any insight you might be able to provide.

JJ,

You need the FDA's 21CFR177 for your list.

http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm

This will take you to the FDA search page for Title21. Scroll down to 177 and go there.

Also... you should have no problem finding a supplier of food grade items in your area. Easiest to start with Grainger, McMaster-Carr, etc. Grainger even publishes a separate food industry book.

If these don't meet your needs there is a company called Columbia in Dayton Ohio that has fab'd me several custom food grade items. They can come up with just about anything you need in seals or hoses.

Good luck on your project.

Thanks Guys!

Armed with this info, I will be able to discuss my requirements with suppliers and manufacturers much more intelligently...despite myself. I always appreciate info on companies to check out as well, so if you think of any more I'd love to hear about them. Thanks again.

Hi jj!

Have you tried researching the Smithers/ RAPRA library of rubber and polymer materials? If you are not familiar with RAPRA, you will really enjoy meeting them! They are the Rubber and Plastics Research Association!

If you Google them and find RAPRA Ltd., ask to speak to Laura Woods. She is their North American marketing manager and get you connected to the library - or someone who can help!

Continued succcess to you!

A number of materials that may be safe for contact with dry foods may not be safe for contact with drinking water

Look for compliance with National Sanitation Foundation standards:

NSF/ANSI std 14 Plastic Piping System Components

NSF/ANSI std 61 Drinking Water System Components

Pipe/tubing manufacturers, Plastic material suppliers etc. all KNOW and should be able to provide certification that their products meet the above (especially # 61) standards.

Good Luck
