Introduction

Polystyrene, also known as PS, has been mass-produced since 1930.
  - It is a thermoplastic polymer.
- Applications: PS is commonly used for inexpensive packaging materials, pens, safety razors, flatware, and CD jewel boxes. In Styrofoam forms, PS is used to make high-throughput, thin-walled, easy-to-mold parts where structure is not paramount.
- General properties: It is an inexpensive material that is not structurally strong but easy to mold. It machines well, and is highly transparent.
- Trade Name: Novacor 555.
