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. The first book of its kind in this field Analyzes the reasons behind odor formation and provides the best methods to prevent odors in various materials Contains information on testing of odor changes and the relationship between odor and toxicitywas poured into 500 ml glass flasks, which were then sealed with plastic screw tops with a headspace adapter and ... 32 g of pellets were placed into 250 mL odorfree water and shaken for four hours at 25AdC.45 The water samples (10 mL of each) ... tube was 225 mg.46 The filled tubes were thermally cleaned at 320AdC for 8 h with a purified nitrogen flow.46 Volatiles ... tubes using a calibrated air pump.46 Volatiles from polyethylene packaging, 47 polypropylene irradiated with I³rays, 48anbsp;...
