The best way to be certain that you are employing the optimum material of construction with DMA is to follow your company's published recommendations - usually found in your company's piping code or standards. This is, of course, assuming that your company has a code.

In the event your company has no standards for their materials of construction, then go immediately to the other "experts": the manufacturers of DMA. These would be Huntsman, Dow, and others around my neck of the woods (the Texas Gulf Coast). The manufacturers know exactly what you can use safely and what is not recommended as material of construction - for the pure compound as well as for solutions. They will be elated to share this information with you in order to cultivate you as a customer of their product. Normally, MSDS information does not include good and specific M.O.C. information.

If you are going to use the M.O.C. recommendation for specifying actual equipment, then do not depend or rely on information obtained through an internet forum. Employ the manufacturer's recommendation or that of a paid, recognized, expert engineering consultant.

If you are a student using this information on your homework problem or an engineering design problem, then you can try using "hear say" info. But for serious, industrial applications you should only rely on recognized experts.
