Drying for Moisture Sensitive Materials


Test ID  
D-017

   
Description  
Pelletized samples are placed in a vacuum oven or fluid bed dryer for the customer specified time and temperature. Small samples are taken at routine time intervals and moisture is measured by way of Karl Fisher titration. Specimens are continually monitored to ensure the material reaches the desired target moisture.    
Data  
Moisture values and actual dry times and temperatures are reported.  
Replicates (# of times this test is repeated)  
2  
Samples  
.5 - kg of pellets [details]

   

Application
 
Some polymers are moisture sensitive, meaning they absorb moisture. This moisture content can adversely affect the finished molded product. It is critical that samples be dried to the proper moisture level to produce meaningful test data that accurately represents the material.
