Webmicrocrystalline wax, any petroleum-derived plastic material that differs from paraffin waxes in having much finer and less-distinct crystals and higher melting point and viscosity. Microcrystalline waxes are used chiefly in laminated-paper products, in coatings and linings, and in adhesives, sealing compositions, and various types of polishes. In contrast to … WebExperimental Investigation of Rheological Behavior and Wax Deposition of Waxy Oil–Disulfide Oil Systems. ... Influence of polymeric additives on paraffin wax …
WebThe wax appearance temperature (WAT) is the temperature at which the first wax crystals start to form, on cooling of paraffin/solvent systems. There are a number of different WAT determination methods, including: density and viscosity variation, differential scanning calorimetry, laser dispersion, and chromatography. WebFeb 20, 2016 · The macrocrystalline paraffin wax (PARAFINA BR 140/145 °F—1% and 2% oil, Petrobrás) has a viscosity of 6.01 cSt at 90 °C. The two types of wax were studied …
WebSep 1, 2002 · This paper reviews investigations into the composition of macro- and micro-crystalline paraffin waxes, focussed on the structure of non n-alkanes. The review covers a wide spectrum of investigations from the last 50 years. Applied analytical methods and results of paraffin wax analysis are compiled. WebOn the other hand, iso-paraffin wax, which is produced during the crude oil refinery process, is identified as a micro-crystalline wax. Iso-paraffin wax has better engine-combustion characteristics due to its high melting point and molecular weight .
