WebHydroxypropyl methylcellulose (HPMC) or hypromellose refers to soluble methylcellulose ethers. HPMC is used as a thickening agent, binder, film former, and hydrophilic matrix material. HPMC polymers for fabricating hydrophilic matrix systems are available in various viscosity grades ranging from 4000–100,000 mPa s. WebISOLUBE 3400 are economical, low viscosity metal forming neat lubri- cants, versatile, easy to clean, suitable for micro-lubrication. ROLLING ISO-MILL product lines are customised rolling fluids, especially for wire rod production, on continuous casting and rolling mills.

WebThe character of volcanic eruptions are largely controlled by the viscosity – “ gooeyness ” or resistance to flow – of the magma: Low viscosity fluids flow more easily than high viscosity fluids. Familiar fluids range in viscosity. Water has low viscosity (flows easily) while syrup and honey have greater viscosity. WebDec 11, 2024 · A viscosity index below 100 is considered low, while a VI higher than 200 is considered very high. High performing suspension oils sometimes have Vis in the range 300-400. Mineral oils have VIs below 100, PAO synthetic oils around 150, while high-oleic canola oil has a VI of 220.
