What is Polystyrene?

Polystyrene is a thermoplastic polymer derived from styrene monomers. It can be solid or foamed and is known for its transparency, rigidity, and insulating properties. It is classified into different types based on its production process and application.

Types of Polystyrene

1. General-Purpose Polystyrene (GPPS)

   • Transparent and brittle.
   • Used in food packaging, laboratory ware, and electronics.

2. High-Impact Polystyrene (HIPS)

   • More durable due to added rubber content.
   • Used in appliances, automotive parts, and toys.

3. Expanded Polystyrene (EPS)

   • Lightweight foam material with excellent insulation.
   • Commonly used in packaging and construction insulation.

4. Extruded Polystyrene (XPS)

   • Dense foam with superior moisture resistance.
   • Used in insulation boards for buildings.

5. Polystyrene Copolymers

   • Modified versions for specialized applications.
   • Used in medical devices and high-performance materials.
