The materials used in manufacturing hydraulic seals are also vital to their performance. Common materials include rubber compounds, polyurethane, and PTFE (Polytetrafluoroethylene). Each material offers different advantages and is selected based on the operating environment. For example, PTFE seals are highly resistant to chemicals and extreme temperatures, making them ideal for demanding applications.

The incorporation of fragrance into plastics is achieved through selected additives that can impart specific scents to the final products. These additives can be designed to release fragrance gradually over time, a feature particularly desirable for items such as scented candles, air fresheners, and personal care products. The process involves embedding microcapsules of fragrance within the plastic matrix, which slowly release the scent when the product is used or comes into contact with air.
