wheel bearing grease seal. If any issues are detected, the seals should be replaced promptly to prevent further damage to the bearings.
The choice of antioxidant is crucial and can depend on several factors, including the type of plastic material, processing conditions, and the intended application. For instance, polyolefins, which are commonly used in various applications, often benefit from hindered phenolic antioxidants due to their thermal stability and compatibility with the substrate. Meanwhile, engineering plastics like polycarbonate may require different types of antioxidants that can provide protection at elevated temperatures.
