Plasteel Corpoation has been in business since 1941 and has been working with EPS foam since the mid 50's. Smoothfoam is our brand name for EPS or Expandable Polystyrene. It is a smooth, closed cell foam. It is often referred to as the smooth Styrofoam. It is molded from tiny beads into many shapes like balls, bells, eggs, miniature fruit shapes and more. Because of its smooth surface it is excellent for painting. It is also very durable, making it great for projects requiring pins or glue. STYROFOAM Brand Foam is extruded (cut out) of large blocks. It has a rough open cell texture. Styrofoam also comes in balls, bells and egg shapes. Styrofoam is good for floral arrangements, or other projects requiring the insertion of pipe cleaners or other thick parts.
