Ray was trying to develop a more flexible insulator. He combined styrene with isobutylene under pressure. When the pressure was released, he found that the isobutylene evaporated and made a foam polystyrene with bubbles in it. “Styrofoam” was born and picked up quickly because it was 30x lig...
1 Plastic seats begin as pellets of polystyrene. A worker feeds the pellets into a hopper attached to an injection molding machine. From the hopper, a precisely measured amount of pellets flows into a A plastic toilet seat is made by a process called injection molding, where plastic pellets...
Sporks can be made from all types of materials including steel, wood, glass, and plastic. By far the most often used material is plastic, specifically polypropylene and polystyrene. These materials are combined with other additives to create the finished utensil. It is important to note that ...

resistance and is used in medical and electrical equipment, house wares, and connectors in polyvinylchloride ducts and piping. Polyester resins made from styrene, called polystyrene, are used to construct components in boats, automobiles and electrical products. Styrene butadiene is a synthetic rubber....
Polystyrene is mostly non-recyclable, and even when it is recyclable, less than 10% of it will be recycled. Just skip the plastic containers where you can. As with the cutlery, if you’re picking up lunch every day and can’t sit down, then either take in your own lunchbox or make...
