Polystyrene beads are small, lightweight spheres made from the polymer polystyrene. They are commonly used in various applications, including packaging, insulation, and crafts. These beads can be produced in different sizes and densities, making them versatile for different uses. In addition to their practical applications, polystyrene beads are often found in bean bag chairs and decorative crafts. They are known for their buoyancy and ability to resist moisture, which makes them suitable for use in fishing floats and other water-related products. However, their environmental impact has raised concerns, leading to discussions about recycling and alternatives.
