2. Automotive Industry In vehicles, hydraulic systems are used for power steering, brakes, and automatic transmissions. Oil seals are essential for these systems to function correctly.

The design of oil seals often incorporates a lip that makes contact with the shaft. This lip is engineered to create a tight seal, thus minimizing the chances of leakage. Additionally, some oil seals come equipped with a spring to enhance the sealing force and maintain contact with the shaft, especially in dynamic applications.

3. System Flushes Occasionally flush the hydraulic system to remove any debris that might compromise the seals.

Shaft seals serve as barriers between rotating shafts and stationary components. They are integral in containing lubricants and preventing external contaminants from entering the machinery. In high-temperature environments, the challenges are amplified. High temperature shaft seals must resist thermal degradation, maintain their sealing properties, and endure the harsh conditions often present in such settings.

3. Polyurethane Seals (PU) These seals offer excellent wear resistance and are often used in high-load applications. Their higher cost may be justified by their superior performance and longevity.

Titanium dioxide is found in pretty much all makeup & sunscreen.

And studies have long shown that products applied to the skin end up in the bloodstream within half an hour. With penetration rates depending on where they are applied. Absorption rates for your face & scalp are 5-10 times higher than on other parts of our body (Hotchkiss 1994).

Not to mention that in 2005, the Environmental Working Group published a combination of two studies that found toxic chemicals in the umbilical cord blood of newborn babies born in the U.S. They screened for more than 400 chemicals, and an astounding 287 toxins were detected within the umbilical cord blood of these newborns. Of these 287 chemicals, 217 were neurotoxins, and 208 are known to damage growth development or cause birth defects.

Mars Wrigley, the company that makes Skittles, is being sued by a California man who claims the candy contains a known toxin that poses such a serious health risk that Skittles are unfit for human consumption.

Résumé–Cet article traite de la découverte de lithopone phosphorescent sur des dessins à l'aquarelle, datés entre 1890 et 1905, de l'artiste Américain John La Farge et de l'histoire du lithopone dans l'industrie des pigments à la fin du 19e et au début du 20e siècle. Malgré de nombreuses qualités souhaitables pour une utilisation en tant que blanc dans les aquarelles et les peintures à l'huile, le développement du lithopone comme pigment pour artistes a été compliqué de par sa tendance à noircir lorsqu'il est exposé au soleil. Sa disponibilité et son usage par les artistes demeurent incertains parce que les catalogues des marchands de couleurs n'étaient généralement pas explicites à indiquer si les pigments blancs contenaient du lithopone. De plus, lors d'un examen visuel, le lithopone peut être confondu avec le blanc de plomb et sa phosphorescence de courte durée peut facilement être ignorée par l'observateur non averti. À ce jour, le lithopone phosphorescent a seulement été documenté sur une autre œuvre: une aquarelle de Van Gogh. En plus de l'histoire de la fabrication du lithopone, cet article décrit le mécanisme de sa phosphorescence et son identification à l'aide de la spectroscopie Raman et de la spectrofluorimétrie.

Yet another study, this one published in 2006 by the International Agency for Research on Cancer said there was insufficient evidence to conclude that titanium dioxide causes cancer. However, the study also categorized the ingredient as a potential human carcinogen.
