Finish Line Teflon Synthetic Grease

Product Information

Special greases with added solid lubricants, such as graphite, or molybenum disulfide (MoS 2). Usually used for high load and pressure bearing greases. Special additives, when they are notneeded, in addition to increasing the price, can have a negative affect on grease properties for the intended use! There’s absolutely no data (I’ve already provided this but you subsequently deleted the comment) in this entire article about how greases compare to one another in regard to wear and pitting, prevention of oxidation, washout, among any number of other scientific indicators. Just pure conjecture. You ever wonder why your white lithium grease looks a little brown when you pull it out even after short intervals? It’s because of oxidation, it’s not near the top of greases in it’s oxidation prevention properties. But since you never actually look into this data you’ll never understand greases in general.” You’ve still yet to prove (you using actual scientific studies…) why NLGI 2 AND having a basic lithium composition is the ‘optimal’ Many soft metals, like copper, silver, gold, zinc, lead etc. have low shear resistance and can be used as a lubricant, put in a thin layer over sliding hard surfaces. Soft metal films are useful for tempereatures up to 1000°C, but are less often used nowadays.

History [ edit ] Advertisement of the Happy Pan, a Teflon-coated pan from the 1960s Advertisement for Zepel, the trade name used to market Teflon as a fabric treatment PTFE thermal cover showing impact craters, from NASA's Ultra Heavy Cosmic Ray Experiment (UHCRE) on the Long Duration Exposure Facility (LDEF) Logo of Teflon, the commonly known brand name of PTFE-based compositions manufactured by ChemoursZero data to show the actual properties of the actual greases to washout or corrosion inhibitance even though it is listed as a requirement.

The research paper provide by Reason as showing that “… polyurea is just a superior grease” is likewise flawed. The results do show that, on a friction/wear test, polyurea grease – with no additives – outperform Lithium – with no additives. However of the three additives tested, Lithium outperforms Urea when used with ‘MoDTC’, and they are equivalent when ‘ZnDTP’ is used. So when it comes to comparing the two – with additives – there is no clear winner. The resulting polymer is terminated with sulfate ester groups, which can be hydrolyzed to give OH end-groups. [17] Trust what is written on the label, as a marketing slogan. However, there are lithium complex greases with better washout resistance than some “marine greases”. Same goes for other properties. Consistency (hardness) is measured with a cone, by methods standardized underASTM 217 IP 50, or DIN 51804, part 1. Measuring unit represents depth the measuring cone enters the tested grease. Testing procedure is shown in the picture 1. Picture 2 Criterion 7 – Low price. Out of two greases that bothsatisfy previously noted criteria, it makes sense to choose the cheaper one. It makes no sense for lubrication, in a medium term, to cost more than replacement of a bearing.

As far as I know, those are decent-quality calcium-based greases, that are softer than NLGI2 hardness, not aggressive on plastics, rubber or metal.

I use relatively cheap all-purpose lithium complex grease and it’s performed very well over the years – both with mine and customer bicycles. PTFE is one of the best-known and widely applied PFAS commonly described as persistent organic pollutants or "forever chemicals". Only since the start of the 21st century has the environmental impact and toxicity to human and mammalian life been studied in depth. For decades, DuPont used perfluorooctanoic acid (PFOA, or C8) during production of PTFE, later discontinuing its use due to ecotoxicological and health issues that led to legal actions. Dupont's spin-off Chemours today manufactures PTFE using an alternative chemical it calls GenX, another PFAS. Besides, open grease shelf life is about 5-7 years, closed new lid can be safe to use for about 10. After that, they might degrade – drying out, or base oil separating. Placing the disc caliper behind the fork (a copy of a common design used in motorcycling) results in the braking force trying to pull the hub out of the flanges – downwards. Already answered the logic behind my thinking. However, I have no “scientific” data proving that softer greases don’t stay in place as well as the harder ones. Except experience. Both first hand and other mechanics’.
