PS plastic, or Polystyrene, is a common type of plastic that comes primarily in two forms: foam and rigid solid plastic. These forms have different physical properties and applications.
Types of Polystyrene (PS)
Polystyrene (PS) is a versatile plastic used in a wide range of applications. The two main types are:
- Foam (Expanded or Extruded Polystyrene): This type is lightweight and provides excellent insulation.
- Rigid, Solid Plastic: This form is more durable and is used in products requiring strength and stability.
| Feature | Foam (Expanded/Extruded) | Rigid, Solid Plastic |
|---|---|---|
| Physical Property | Lightweight, Insulating | Durable, Strong |
| Common Uses | Packaging, Insulation | Toys, Appliances |
Applications of PS Plastic
Due to its varied forms, PS plastic is utilized across many industries:
- Packaging: Foam PS is frequently used for protecting items during shipping due to its cushioning properties.
- Insulation: Expanded polystyrene is a cost-effective insulation material for walls and roofs.
- Consumer Goods: Rigid PS is used in toys, appliance housings, and other durable goods.
- Food Service: PS is commonly found in disposable cups, plates, and cutlery.
