In 2017, French researchers from the Institut National de la Recherche Agronomique (INRAE) were among the first to examine the effects of E171 nanoparticles on the body. They fed rats a dose of 10mg of E171 per kilogram of body weight per day, which was similar to human exposure in food. The research, which was published in Scientific Reports, showed that E171 was able to traverse the intestinal barrier, pass into the bloodstream, and reach other areas of the body in rats. Researchers also found a link between immune system disorders and the absorption of titanium dioxide nanoparticles.

  • In conclusion, iridium spark plugs are a top choice for car owners who want to upgrade their ignition system and improve their engine performance. With their durability, efficiency, and reliability, iridium spark plugs offer a range of benefits that make them worth the investment. If you're looking to maximize the performance of your car and extend the life of your engine, consider switching to iridium spark plugs for your next tune-up.


  • Proper installation and maintenance of mechanical oil seals are crucial to ensure their effectiveness and longevity. It is important to select the correct seal design and material for the specific application, as well as to install the seal properly to ensure a tight and secure fit. Regular inspection and replacement of oil seals at recommended intervals are also important to prevent leaks and potential damage to the equipment.
  • Silicone rubber seals have good heat resistance but lower chemical resistance compared to other elastomers.
  • The material choice for rubber locking gaskets is critical. Rubber, with its inherent flexibility, resilience, and ability to conform to irregular surfaces, makes an ideal sealing solution. Different types of rubber, like silicone, neoprene, nitrile, or EPDM, are selected based on the specific application requirements. For instance, silicone gaskets excel in high-temperature environments, while nitrile ones offer excellent resistance to oils and fuels.

  • When a valve cover gasket fails, it can lead to several issues. Oil leaks can result in reduced oil pressure, causing engine damage due to inadequate lubrication Oil leaks can result in reduced oil pressure, causing engine damage due to inadequate lubrication Oil leaks can result in reduced oil pressure, causing engine damage due to inadequate lubrication Oil leaks can result in reduced oil pressure, causing engine damage due to inadequate lubricationauto valve cover gasket. Leaking oil can also contaminate the spark plugs, leading to misfires or difficulty starting the engine. Furthermore, oil dripping onto hot engine parts could ignite, posing a serious fire hazard.

  • One of the key factors that determine the effectiveness of an oil seal is its design. Engineers must consider factors such as the shape, size, and material composition of the seal, as well as the specific requirements of the machine it will be used in. For example, a seal used in a high-pressure environment may need to be reinforced to withstand the increased forces.

  • Multiple materials and compounds are used to make oil seals. Some of the oldest materials still used today include felt and leather compounds. However, the trend in mass production has experienced a shift towards synthetic elastomers or rubber.
