Polystyrene is a colorless, transparent thermoplastic that softens slightly above 100°C; (212°F;) and becomes a viscous liquid at around 185°C; (365°F;). It is resistant to acids, alkalies, oils, and alcohols. It is produced either as a solid or as a foamed plastic marketed under the trade name Styrofoam. Its many uses include electrical and thermal insulation, translucent window panels, storage-battery cases, and toilet articles. polystyrene a synthetic thermoplastic material obtained by polymerizing styrene; used as a white rigid foam (expanded polystyrene) for insulating and packing and as a glasslike material in light fittings and water tanks How to thank TFD for its existence?

With the artist's help, the middle-schoolers created 18 panels from expanded polystyrene, learning how to cut the foam with a hot wire and create different textures by using various scraping and cutting techniques. What was once large-scale use of expanded polystyrene as shock protection for computers and other sensitive products has now been sharply reduced, resulting in smaller overall packaging and less energy consumption. Chemline has introduced CHEMTHANE 7050, a spray-applied, 100% solids seamless polyurea "hard coating" that is designed to protect Styrofoam or expanded polystyrene (EPS) architectural shapes from damage, including thermal expansion, water intrusion, or direct impact. |
