Oil seals can be made from various materials, including rubber, silicone, and polyurethane. The choice of material often depends on the operating conditions such as temperature, pressure, and the type of lubricant being used. For the 50x65x8 oil seal, nitrile rubber (NBR) is commonly utilized due to its excellent oil resistance and durability in a range of temperatures.

On the other hand, HALS are a unique class of stabilizers that work by scavenging free radicals generated during the photodegradation process. By trapping these free radicals, HALS significantly slow down the degradation of the polymer chains, preserving the mechanical properties of the plastic. This mechanism allows HALS to be effective even in small concentrations, making them a popular choice in various applications.
