Moisture Analysis of Polymers

Moisture Analysis of Polymers

Moisture Analysis of Polymers

(OP)
Would anyone know where to obtain recommended setting (Drying Temperature & Drying Time) for carrying out moisture tests on polymer resins (PC, PA 6, PA 11, PA 12, ABS, Pebax's etc)

RE: Moisture Analysis of Polymers

Could you please clarify? If you want to know the moisture content then don't dry it at all. Once you start drying the polymer will gradually lose weight down to some equilibrium value depending on the temperature.

The setting are for the Moisture analyser. I have a MB35 moisture anaylser and I want to set up specific programs for PC, Pebaxs, etc. (Example for PC, start temp 140C for 5 mins) The analyser will weight before and after the program has finished. It's part of incoming inspection paln to monitor moisture content in resins before they're processed. I looking to see if there are general recommendations for the analyser machine settings for different polymers?

PET, ABS and PMMA are given in the online User's Guide.

So in essence:

Weight program automatic
Time 20 minutes
Temperature Tg of the polymer plus 20°C
