5.4 – Material not drying correctly – Feedback Form

Drying is accomplished when all material reaches the proper temperature, and is then placed under
sufficient vacuum for a sufficient period of time.

Measurement of moisture content of material, both prior to and after drying, is accomplished by using a
moisture analyzer such as one manufactured by Arizona Instruments.

If you are not obtaining the results you want or if you would like us to test your material to determine the
optimal drying cycle time, please provide us with the following information below.

A sample of your material may be required for our own testing. We would need at least 35 pounds.

General material type: (PET, NYLON, etc.):

Manufacturer:

Material designation:

Desiccant dryer recommended drying temperature:
