Health and environmental regulation

The Effects of Health and Environmental Regulation on Technological Change in the Chemical Industry Theory and Evidence... 

The addition of asbestos fibers at one time provided excellent thixotropic adhesive formulations, especially at elevated temperatures. However, health and environmental regulations have severely limited the use of this material. Today, fumed silica, precipitated calcium carbonate, certain clays, and cellulose and other fibers offer thixotropic properties at relatively low levels of loading.

It is well known that most polymers leaving the polymerization reactor contain various but small amounts of unreacted monomer, solvents, water, and/or various reaction by-products. The presence of these volatiles in the polymer is undesirable. Their concentrations may range from several parts per million to several tens of percentage. Their separation from bulk polymer is necessary to improve polymer properties, to recover monomer and solvents, to meet health and environmental regulations, to eliminate odors, and/or to increase the extent of polymerization. This process of devolatilization is nsnally performed above the glass transition temperature of the polymer. The reader is referred to Albalak [21] for detailed discussion of the theory of devolatilization and various devolatilizing equipments.

To comply with health and environmental regulations, neither T1 nor Hg can be considered for widespread application in superconductors, owing to the risk of their accidental toxic release. Even though T1 in superconducting cuprates is in a 3-i-valence state (and is therefore less toxic), its easy reduction to the l-i- oxidation state and its high cationic mobility are dangerous features. Tl can readily replace K due... 

Historically, over time TAPs have been manufactured from feedstocks based on phenol, cresol, and/or xylenols. Different feedstocks will affect plasticizer performance and toxicity characteristics. Consult the latest government safety, health, and environmental regulations before choosing a specific grade of TAP for rubber use. 

With advent of new teehnology, solvents were changed to account for health and environmental regulations. Some of the currently used systems are listed below.
