Auditing Consulting Sourcing Training. With nonhomogeneous materials, such as laminated forms, the rate of water absorption may be widely different through each edge and surface.
For example, Table 1 shows the time to approximate time saturation for various thickness of nylon Assurance Testing Inspection Certification. The data sheds light satm the performance of the materials in water or humid environments.

Even for otherwise homogeneous materials, it may be slightly greater through cut edges than through molded surfaces. The effect upon these properties of change in moisture content due to water absorption depends largely on the type of exposure by immersion in water or by exposure to high humidityshape of the part, and inherent properties of the plastic. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.
