Product abuse high temperatures

Plasticity, or consistency, of an edible oil product depends on the amount of solid material, the size, shape, and distribution of the solid material, and the development of crystal nuclei capable of surviving high-temperature abuse and serving as starting points for new desirable crystal growth. The factor most directly and obviously influencing the consistency of a plastic shortening is the proportion of the solid... 

To date, the principal reason for using electrolyte additives in lithium-ion cells has been stabilizing the anode s SEl, which is critical to cyclabiUty of Li-ion cells, because at elevated temperatures SEl deteriorates due to the reaction with LiPFe-containing electrolytes [7-10] The loss of capacity and power from a cell stored at elevated temperature has been attributed to the presence of thermal decomposition products of the electrolyte in the anode SEl [10], On the other hand, additives that inhibit the thermal decomposition of electrolytes with LiPFe were expected to improve the capacity retention and decrease resistance in thermaUy abused cells. Thus, the inhibition of the thermal reactions between the anode SEI and LiPFe-containing electrolytes would lead to improved high-temperature performance of the tested cells. Since different famUies of additives have varied mechanisms of high-temperature performance enhancement, combinations of the two (or more) different additives were used in an anticipation of their cooperative effect. 

The addition of BrCl to the depolarizer may also prevent the formation of sulfur as a discharge product, at least in the early stage of the discharge, and minimize the hazards of the Li/SOa2 battery attributable to sulfur or discharge intermediates. The cells show abuse resistance when subjected to the typical tests, such as short circuit, forced discharge, and exposure to high temperatures. ... 

An increasing variety of automotive parts is being made by thermoforming processes. Many of these products are made from rubber-toughened polypropylene, which are relatively stiff and can withstand a high level of physical abuse over a ivide range of temperatures. When such parts are used in high visibility areas, such as wheel arches, air dams, truck fenders, and... 

Studies indicated that identification of spoiled seafood products by sensory evaluation is due to detection of putrefied odor associated with spoilage (8). Rapid detection of spoilage with sensory evaluation results from microbial action due temperature abuse or high initial levels of microorganisms (9). 

Krytox seems like a product from heaven, as many of its attributes are spectacular. It is a fluorinated grease and is therefore impervious to hydrocarbon- and water-based solvents. It cannot bum, so it has no flash point and can be exposed directly to oxygen, even at high pressures. It can be used over the widest temperature range of all the greases and works equally well with stopcocks as with joints. It has remarkable stability characteristics and can withstand long-term abuse. Best of all, Krytox greases are nontoxic. 

It is obvious that the cured brake blocks must be very strong if they are to withstand the abuse that friction products must endure. The horsepower of an automobile may be as high as 50 to 100, but the brakes on the same automobile must be 400 to 600 horsepower if the brakes are to stop the automobile in one-sixth the distance required to accelerate the automobile, by its engine, to speeds where brakes are applied to stop the automobile. The major fraction of the kinetic energy of the automobile is suddenly converted to heat in the brakes, and the temperature may rise abruptly from 0 °F to 1000 °F in a matter of seconds. Thermal shock alone would destroy an inferior brake pad.
