Aloha Art2Gecko. The answer is Yes to freezing. The following expalins:
During the mechanical recovery process that the MDOR plant utilizes, the scrap tire is disintegrated through a number of "cryogenic processes" into the most basic rubber, steel and textile components. Vulcanized rubber represents the main component of the scrap tire, and is processed into rubber granules and industry leading pure microscopic rubber powders. The physical and chemical properties of the resulting powders can be employed as not only substitutes for much more expensive primary raw materials but also as a starting material for high-value products and innovative processing methods
In physics or engineering, "cryogenics" is the study of the production of very low temperatures (below –150 °C, –238 °F or 123 K) and the behavior of materials at those temperatures.
Cryogens, like liquid nitrogen, are further used for specialty chilling and freezing applications. Some chemical reactions, like those used to produce the active ingredients for the popular statin drugs, must occur at low temperatures of approximately -100 °C. Special cryogenic chemical reactors are used to remove reaction heat and provide a low temperature environment. The freezing of foods and biotechnology products, like vaccines, requires nitrogen in blast freezing or immersion freezing systems. Certain soft or elastic materials become hard and brittle at very low temperatures, which makes cryogenic milling (grinding) an option for some materials that cannot easily be milled at higher temperatures.
Hope that helps,
