Moisture Analysis

This characterization technique is used to determine the moisture that a material contains through weight loss. Many polymers are hygroscopic and need to be processed in a dried state to decrease voids in parts. Moisture analysis is typically used to check if the moisture content in a material is low enough for processing.

Conventional ASTM Standard:

D6980-17

D6980-17

This standard provides methods for moisture testing most standard materials including polyethylene, polycarbonate, acrylonitrile butadiene styrene, polyether ether ketone, and other common polymers. Samples of pelleted polymer resins are placed in the moisture analyzer and heated according to standard recommendations for the material. The moisture in the material is quantified through the material’s percentage of weight lost due to heating.
