Where to find shrinky dink paper

The properties of all solid materials, including polymers, depend on their processing history. The temperature, method, and speed of processing are key variables. Processing refers to the technology used to convert a raw material a polymer, for example into an article of a certain shape.

Most plastic films and sheets are produced by extrusion. In the extrusion process, the raw material is conveyed down a heated barrel by a rotating screw. The material melts as it proceeds down the barrel and is forced through a die which gives it its final shape.

This means the material is soft and rubbery. The forced flow through the die causes stretching in the direction of flow, but to produce a biaxially stretched film, further stretching in the direction perpendicular to the machine direction is required. The stretched film is then taken up by several rollers.

These rollers are usually chilled to quickly cool quench the rubbery film. The rapid cooling of the film maintains the stretched shape. When the film is heated, the polystyrene chains return to their more random configuration. The polystyrene chains are said to "remember" their most stable random configuration, even though they can be "frozen" into a less stable configuration by rapid cooling during manufacture.
