There's No Such thing as a STYROFOAM™ Cup
STYROFOAM™ Brand Foam is a registered trademark of The Dow Chemical Company and has been a valued asset for more than 60 years.
The STYROFOAM™ Brand name is often misused as a generic term for disposable foam products such as coffee cups, coolers and packaging materials. These materials, however, are made from expanded polystyrene products (also known as EPS or beadboard). STYROFOAM™ Brand Extruded Polystyrene Foam Insulation has a higher insulation value ("R-value per inch") than EPS and STYROFOAM™ Brand Extruded Polystyrene Foam Insulation had a higher moisture-resistance than EPS as shown by ASTM C578 industry specification Type requirements.
There isn't a coffee cup, cooler or packaging material in the world made from actual STYROFOAM™ Brand Extruded Polystyrene Foam Insulation. STYROFOAM™ is a registered trademark of The Dow Chemical Company that represents its branded building material products, including rigid foam and more.
Dow holds more than 250 trademark registrations worldwide for the STYROFOAM™ brand. Learn more about trademarks and service marks of Dow, along with guidelines for correct usage.
