It’s true that titanium dioxide does not rank as high for UVA protection as zinc oxide, it ends up being a small difference (think about it like being 10 years old versus 10 years and 3 months old). This is not easily understood in terms of other factors affecting how sunscreen actives perform (such as the base formula), so many, including some dermatologists, assume that zinc oxide is superior to titanium dioxide for UVA protection. When carefully formulated, titanium dioxide provides excellent UVA protection. Its UVA protection peak is lower than that of zinc oxide, but both continue to provide protection throughout the UVA range for the same amount of time.
As suppliers of titanium dioxide, we recognize the significance of maintaining consistent quality and supplying our customers with products that meet their specific requirements
Heat and attrition are generated by the parts moving against each other. The sealing function can only be ensured if an intentional defined leakage of oil is able to exit for seal lubrication, preventing seal wear and possible failure, while a tight static seal between shaft and sealing lip must be assured when the shaft is stationary.
- There are several types of spark plugs, each tailored to specific engine requirements. Conventional spark plugs, with a single ground electrode, are the most common. Iridium and platinum spark plugs, known for their durability, have multiple electrodes and longer lifespan. Double iridium or double platinum spark plugs further enhance efficiency and longevity.

When selecting the oil seal that is right for your machine, it is important that the oil seal be appropriate for the requirements of the usage environment and that it be easily acquired for replacement.
In this month's column, How to select the right oil seal, we conveyed the following points:
1) Oil seal shape and material should be selected based on the housing, substance to be sealed, pressure, rotational speed, total eccentricity, and air-side conditions.
2) Oil seals can show good sealing performance in combination with properly designed shafts and housings.
3) Oil seal performance is affected by not only the type and material of the selected oil seal, but also a variety of other factors, such as operating conditions, total eccentricity, rotational speed, the substance to be sealed, and lubrication conditions. For this reason, diligent care is required in oil seal selection.
When selecting spark plugs for vehicles, it is essential to consider factors such as compatibility, heat range, electrode design, and material composition. High-quality spark plugs, including iridium spark plugs, are designed to withstand the demanding conditions of automotive operation, providing reliable ignition and combustion. Choosing reputable suppliers and manufacturers known for producing high-quality spark plugs is crucial to ensure the reliability and longevity of these critical components in the vehicle's ignition system.

Minor lip The minor lip prevents the entry of dust and contaminants from outside.
Lubricant can be retained in the space between the main lip and the minor lip.
