One common type of oil seal is the lip seal, which features a flexible lip that makes contact with the rotating shaft to create a tight seal. Lip seals are often used in automotive engines, gearboxes, and industrial pumps due to their effectiveness in preventing oil leaks. Another popular option is the mechanical seal, which uses a rotating element to maintain constant contact with the shaft, ensuring a reliable seal even at high speeds and pressures.

The applications of redispersible polymer powders are extensive and varied. They are commonly used in the production of tile adhesives, self-leveling compounds, waterproofing membranes, and repair mortars. In tile adhesives, for instance, RDPs improve the wet adhesion and initial grab of the adhesive, allowing tiles to bond securely to substrates. In self-leveling compounds, they enhance the flow properties, ensuring an even application that settles uniformly on surfaces. In waterproofing applications, RDPs contribute to the formation of a barrier that resists water infiltration while also offering flexibility to withstand movements within the structure.
