Over the several years, many have combined up the brand identify STYROFOAM with the polymer expanded polystyrene. It is quite common to use STYROFOAM as a generic phrase for foam coffee cups and consider-out containers, which are normally created of expanded polystyrene. The previous is a trademark of the Dow Chemical Company for its extruded polystyrene item, which differs vastly from the generic expanded selection. Despite Styrofoam that equally are rigid, shut-cell, thermoplastic foam merchandise, they are created differently and have unique qualities as effectively.
STYROFOAM brand name extruded polystyrene is a end result of stress and very hot temperatures. Reliable polystyrene crystals, additives and a blowing agent go by way of an extruder, where they are blended and melted into a viscous, plastic fluid. This mixture is then fed to a die and is shaped, cooled and cut.
Expanded polystyrene, on the other hand, is produced of very small, interconnected beads of polystyrene. For the duration of generation, pentane gasoline is dissolved into the polystyrene base to attain expansion. When shaped, like STYROFOAM, they can be molded to specified specifications.
Several in the design enterprise desire STYROFOAM for developing insulation thanks to its substantial R-benefit (degree of heat resistance), great compression energy, and resistance to humidity. Expanded polystyrene is the perfect selection for people in the industry for packaging and soundproofing material, as nicely as void fill.
The exclusive characteristics that STYROFOAM and expanded polystyrene possess make them best for particular reasons, and programs will count on the undertaking needs. Seeking the specialist guidance of trusted suppliers can support figure out which foam product greatest satisfies a undertaking.
