Grease is a semi-solid lubricant composed of oil and a thickener, offering persistent adherence and moisture resistance; oil is a liquid lubricant, excelling in temperature stability and ease of application.
example of a grease with a synthetic base oil is another multipurpose grease, AeroShell Grease 7, which is used extensively on commercial aircraft where there is frequent exposure to extremely low temperatures at altitude. AeroShell Grease 7 has an operating temperature range of -73/+149...

Red greases are also multipurpose and tend to be synthetic. The color red could indicate a higher temperature threshold, but that is not always the case. Red grease will provide lubrication and protection to mechanical equipment and parts. Red and dark blue greases are often interchangeable, but...
What Is Softening Point? Synthetic and natural products can gradually soften its temperature rises and melt over a relatively large temperature interval. Generally, the softening point test is one of the few easily achievable methods available to thermally characterize substances such ...
If I’m solo, theVango Compactcanister stove (direct/eBay) or ahomemade alcohol stove(how-to video) usually do the job. In pairs/groups or on longer trips, theAlpkit Koro(direct) is lightweight and good for canister gas alone, whereas theMSR WhisperLite Universal(review/direct/REI/MEC/eB...
What is the effect of stationary phase film thickness on gas chromatograms? Why does urea have a sharp melting point but glass does not? Polymers are different from small molecules. How does polyethylene differ from oil, grease, and wax, all these materials being essentially ch2? Why does a...
