Several reasons are behind formation of odors in materials, including the following:
Use of other materials than polymer, especially materials required in processing
Use of various process parameters and their severity in degradation of components of formulation
Recycling of polymeric materials
Contact with natural products (food, cosmetics, etc.)
Storage
Migration-evaporation
Storage in the same space
Diffusion-related properties
The above reasons are analyzed for different materials to find out the best methods to prevent odor formation. The book also contains information on testing of odor changes, relationship between odor and toxicity, and the selection of raw materials for fog-free products. The first book in this field, the Handbook of Odors in Materials is needed by anyone interested in materials.
