How styrofoam is made
Nettet11. mar. 2015 · Styrofoam is made of styrene, a liquid hydrocarbon that retains its shape after being heated and cooled. It’s use originated in creating hard plastic items, but in 1941, scientist Ray McIntyre invented a way to create a lightweight, waterproof variant of the plastic called extruded polystyrene. Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam (XPS), manufactured to provide continuous building insulation board used in walls, roofs, and foundations as thermal insulation and water barrier.
