Expanded polystyrene foam (EPF) or the Styrofoam is a plastic material that has special properties due to its structure. EPF is extraordinarily light and can support many times its own weight in water. Because its cells are not interconnected, heat cannot travel through EPF easily, so it is a great insulator. EPF is used in flotation devices, insulation, egg cartons, flats for meat and produce, sandwich and hamburger boxes, coffee cups, plates, peanut packaging, picnic coolers, and definitely is the perfect component for events Styrofoam manufacturing and events fabrication.

Design and Manufacturing Process

Like all plastics, EPF consists of a polymer chain with great molecular weight. EPF is a linear polymer whose basic unit is styrene (C 8 H 8 ) and whose molecular mass is 104, yet when it is linked together as it is in the plastic, its mass can range between 200,000 and 300,000 (because a polymer chain can contain an indefinite number of molecular links, a terminal mass cannot be determined).

First, styrene is made by combining ethylene and benzene. Next, the styrene is subjected to suspension polymerization and treated with a polymerization initiator, which together convert it into polystyrene. The resulting polystyrene beads are then cleaned, and anomalous beads filtered out. For small sell Styrofoam manufacturing, workers then melt, add a blowing agent to, and extrude the beads. To produce smooth-skinned EPF, they pre-expand the beads, dramatically reducing their density. Next they heat and expand them before allowing them to sit for 24 hours so that they can cool and harden. The beads are then fed into a mold of the desired shape to make stunning characters and décor for event fabrication.

Quality Control

Styrofoam manufacturing and event fabrications in UAE are subject to the numerous tests and standards formulated by the American Society for Testing and Materials (ASTM) for plastics in general. Some of these standards concern EPF in particular because of its unique properties, yet some of the tests applied to EPF were developed to measure the properties of other plastics.

The Future

EPF can safely be incinerated and will yield only carbon dioxide and water if the procedure is handled correctly, but the trend in Styrofoam manufacturing has been to recycle it wherever possible. EPF can be recycled into concrete, egg cartons, office products, foam insulation, and garbage cans. Since beginnings of 90’s, new research has focused on ways to reduce CFC use, and on developing alternative blowing agents that will not harm the ozone layer. Recent Styrofoam manufacturing and event fabrications’ in UAE include processes that uses pressurized carbon dioxide to produce smaller, more uniform cells. These in turn provide a foam that is stronger and smoother than earlier foams.
