JECFA previously assessed titanium dioxide at its 13th meeting, at which time the expert committee assigned a “not specified” ADI for the additive due to an absence of significant absorption and a lack of toxicological effects in the available experimental animal and human studies. Since its original evaluation by JECFA, titanium dioxide has become a public point of contention, with its ban being introduced (and then subsequently withdrawn) in California legislation in 2023, a legal battle playing out in the EU over the additive’s ban and classification as a carcinogen in 2022, and the European Food Safety Authority (EFSA) calling titanium dioxide unsafe. However, supporters of titanium dioxide say that claims about its dangers are founded in unreliable studies, and some recent research has supported its safety as a food additive.

  • In the area of photodynamic therapy, TiO2's photocatalytic properties have sparked interestchina titanium dioxide in medicine. When exposed to light, TiO2 can generate reactive oxygen species, which can selectively destroy cancer cells. Chinese scientists have been working on developing TiO2-based photosensitizers for cancer treatment, showing promising results in preclinical studies.

  • In conclusion, the 45x62x8 oil seal is more than just a simple component; it is a critical element in the complex machinery ecosystem. Its role in preserving the integrity of lubrication systems, safeguarding against contamination, and contributing to the overall efficiency and longevity of equipment cannot be overstated. As technology advances and machinery becomes increasingly sophisticated, the importance of high-quality oil seals like the 45x62x8 will continue to grow.

  • If you follow the above instructions, the oil seals should work properly. Also watch the video below for an example of the installation process.

  • In conclusion, the oil tank gasket is a crucial component of any oil tank system. It plays a vital role in preventing leaks and ensuring that the system operates efficiently. By properly maintaining your oil tank gasket, you can avoid costly repairs and replacements, and enjoy a well-functioning oil tank system for years to come.

  • The primary function of the main bearing oil seal is to create a barrier between the rotating shaft and the stationary engine block. This barrier prevents oil from escaping from the engine's main bearings, which are responsible for supporting the weight of the pistons and connecting rods. Without an effective oil seal, oil would leak out, leading to reduced lubrication and ultimately causing severe damage to the engine.
  • The 22% oil seal is another commonly used size that offers similar benefits to the 12% seal. This seal is often found in industrial machinery, such as pumps, compressors, and generators, where it plays a crucial role in maintaining the integrity of the equipment. The 22% oil seal is designed to withstand high pressures and temperatures, making it ideal for use in demanding environments where reliability is paramount

  • Nitrile is the most widely used rubber (elastomer) and it’s recommended as the best for almost all standard applications. This is solely due to the fact that nitrile has some intrinsic properties, such as low cost and compatibility with most environments. Some of the general applications of nitrile are non-latex gloves, automotive transmission belts, footwear, gaskets, synthetic leather, hoses, o-rings, and oil seals.

  • c. Silicone Rubber (SI) – these compounds operate effectively in a broad temperature range of -58⁰ F to 356⁰ F (-50 to 180⁰ C). Silicone rubber is a leading choice for its resistance to both low temperatures and heat. The high lubricant absorbency of the material minimizes friction and wear. These oil seals are usually used as crankshaft seals. Silicone has poor resistance to hydrolysis and should not be used in oxidized or hypoid oils.
