Lithopone was discovered in the 1870s by DuPont. It was manufactured by Krebs Pigments and Chemical Company and other companies. The material came in different seals, which varied in the content of zinc sulfide. Gold seal and Bronze seals contain 40-50% zinc sulfide, offering more hiding power and strength. Although its popularity peaked around 1920, approximately 223,352 tons were produced in 1990. It is mainly used in paints, putty, and in plastics.

The National Cancer Institute tested TiO2 for possible carcinogenicity by the oral route of exposure by feeding rats and mice with TiO2 (size not specified) at doses 25,000 or 50,000 ppm TiO2 for 103 weeks. They concluded that TiO2 was not carcinogenic.Also, the study with rats fed diets containing up to 5 % TiO2 coated mica for 130 weeks showed no treatment-related carcinogenicity. Since the size and other TiO2 properties were not specified or determined, we cannot generalize this conclusion and we have to take into account other possible outcomes of this scenario in different exposure conditions (other size/crystalline structure of TiO2 etc.).

  • There are many spark plug suppliers in the market, each offering a range of products with varying features and specifications. When choosing a spark plug supplier, it is important to consider factors such as the reputation of the supplier, the quality of their products, and their level of customer service.
  • The importance of a thin rubber gasket cannot be overstated. It is a small but critical element that safeguards equipment functionality, prevents costly leaks, and maintains overall system integrity. As technology advances and industries evolve, the demand for more specialized and efficient gaskets will only increase. Thus, the study and development of thin rubber gaskets remain a vital area of research and innovation in the world of engineering and manufacturing.

  • How are Oil Seals made?

  • Spring

  • Regular maintenance and inspection of the valve cover gasket are essential to preempt issues before they escalate. If an inspection reveals signs of deterioration or leakage, it is critical to replace the gasket promptly. While this task is typically straightforward for a skilled mechanic, ignoring it can lead to more extensive and costly repairs down the line.
  • Replacing the valve cover gasket on a 2.0% TSI engine is a relatively straightforward task, but it is essential to use the correct gasket and follow the manufacturer's instructions carefully. Using the wrong gasket or improper installation can lead to leaks and engine damage. It is always best to consult a professional mechanic or refer to the vehicle's service manual for guidance.
  • Replacing a Failed Gasket

  • In the intricate world of automotive engineering, where every component plays a pivotal role in the seamless operation of vehicles, the unassuming 7mm spark plug wire stands out as a testament to innovation and reliability. This essential conduit for electrical current might be small in size, but its impact on an engine's performance is anything but minor.

  • Purpose of an Oil Seal

  • When it comes to vehicle maintenance, one often overlooked component is the shock absorber oil seal. These seemingly insignificant parts play a crucial role in ensuring a smooth and safe driving experience. A damaged or worn-out oil seal can lead to oil leaks, compromising the performance of your car's shock absorbers, and ultimately, your overall driving comfort.

  • Benefits of Oil Seals

  • The length and resistance of spark plug wires are designed to match the specifications of the vehicle's engine, ensuring optimal performance. The wires are also often color-coded or numbered to make installation and troubleshooting easier for mechanics.
  • Resistant to steam, petroleum oils, amine corrosion inhibitors, and hydrogen sulphide.
