1. not readily absorbing or retaining moisture from the air
Usage: technical; scientific

Examples

• Glass is a nonhygroscopic material, making it ideal for storing sensitive compounds.
• The nonhygroscopic properties of silica gel allow it to remain stable in humid environments.
• Engineers selected nonhygroscopic polymers for the aerospace application to prevent dimensional changes.
• Unlike cotton, synthetic fibers are often nonhygroscopic and dry quickly.
• The laboratory used nonhygroscopic containers to protect the powder from moisture absorption.
