This not only reduces heat loss and lessens back pressure, but also provides an effective way to protect the exhaust system from wear and tear, thermal degradation and corrosion.

In some regions ( e . g ., Gulf of Mexico ) methane in clathrates may be at least partially derived from thermal degradation of organic matter, dominantly in petroleum.
23.
Extra video cameras will be installed on some future station parts, and an infrared camera is being developed to check for leaks and thermal degradation, the report said . _ __
24.
The increase in temperature stability by incorporating aromatic units is due to the fact, that the temperature stability of a polymer is determined by its resistance against thermal degradation and its oxidation resistance.
25.
Lubricants meeting API MT-1 provide protection against the combination of thermal degradation, component wear, and oil seal deterioration which is not provided by lubricants meeting only the requirements of API GL-4 and API GL-5.
26.
A variety of methyltin compounds are used as precursors for stabilizers in PVC . Di-and trimercapto tin compounds are used to inhibit the dehydrochlorination, which is the pathway for photolytic and thermal degradation of PVC.
27.
The amount of these components affect directly the properties of the fiber, since the hemicellulose is responsible for the moisture absorption, bio-and thermal degradation whereas lignin ensures thermal stability but is responsible for the UV degradation.
28.
To avoid thermal degradation, it is usually combined with a cooler that cools down the dry blend to the temperature of around 45-55 C . Due to the poor heat conductivity of the cooler, the cooler is usually three times larger than the mixer as the cooling time is proportional to contact surface.
