Some service environments can lead to moisture absorption in rubber and elastomeric materials. Understanding the moisture content of a given material can provide an indication of how it will perform.
High moisture content in certain materials can lead to detrimental effects such as:
- Stress concentration
- Poor processability
- Chemical reactions
Corrosion of the surface that the material is in contact with hygroscopic materials absorb moisture from the surrounding environment and typically require storage in sealed containers. The water content of materials is generally measured through titration on a volumetric or gravimetric basis.
We have years of experience measuring moisture content and the effects of moisture build-up in a variety of applications and industries. Our experts can conduct testing to specific industry standards
or design a custom protocol based on your product or material’s exact service environment.
We have extensive sample preparation
facilities at our rubber testing labs, including on-site molding, thickness reduction capabilities, and a CNC machine, which gives us the flexibility to test a wide variety of materials and product forms.
