Silicones, including polydimethylsiloxane (PDMS), are versatile synthetic polymers known for their flexibility, durability, and thermal stability. They are widely used in cosmetics, sealants, lubricants, and medical devices due to their biocompatibility and non-reactive nature. Silicones exhibit water-repellent properties, making them ideal for protective coatings and anti-foaming agents. Their adaptability across various industries highlights their importance in modern applications.
