The CRC Handbook of Chemistry and Physics is a comprehensive one-volume reference resource for science research. First published in 1914, it is currently (as of 2024) in its 105th edition, published in 2024. It is known colloquially among chemists as the "Rubber Bible", as CRC originally stood for "Chemical Rubber Company". [2]
Cross-linking the fatty-acid chains with sulfur (brown factice) or S 2 Cl 2 (white factice) yields a rubbery material that improves the processing characteristics and ozone resistance of rubber. [1] Varying the amount of factice changes the physical properties of the rubber; molded items might be 5-10% factice, extrusions 15-30%.
The CRC Press was founded as the Chemical Rubber Company (CRC) in 1903 by brothers Arthur, Leo and Emanuel Friedman in Cleveland, Ohio, based on an earlier enterprise by Arthur, who had begun selling rubber laboratory aprons in 1900. [2] [3] The company gradually expanded to include sales of laboratory equipment to chemists.
Worker placing a tire in a mold before vulcanization. Sulfur vulcanization is a chemical process for converting natural rubber or related polymers into materials of varying hardness, elasticity, and mechanical durability by heating them with sulfur [1] or sulfur-containing compounds. [2]
Later research included work on blends of rubber and synthetics, such as nitrile, ethylene propylene rubber and Epoxidised natural rubber. The centre also worked on the performance of tyre retread compounds, showing that natural rubber-rich tyres could perform nearly as well as synthetic tyres in durability, but were more fuel efficient as they ...
Rubber compounding means incorporating rubber ingredients into a rubber mixture so it is evenly dispersed, then the rubber mixture is called a rubber compound. The mill aids in two main steps of rubber processing - mastication and mixing. Mastication is when the raw polymer is sheared and the broken down to create an easier flow. This allows ...
HAVANA (Reuters) -Cuba's national electrical system collapsed early on Wednesday morning after the country's largest power plant failed, the government said, the latest of several such failures as ...
Sheet of synthetic rubber coming off the rolling mill at the plant of Goodrich (1941) World War II poster about synthetic rubber tires. Production of synthetic rubber in the United States expanded greatly during World War II since the Axis powers controlled nearly all the world's limited supplies of natural rubber by mid-1942, following the Japanese conquest of most of Asia, particularly in ...
