Expanded Polystyrene, or EPS, foams are available for a number of applications from protective end caps for fragile equipment, to thermal insulation for medical perishables and foodstuffs, to architectural structure applications. The expanded polystyrene foam is often the most economical choice, and can be shaped and custom formed to fit boxes, crates, or tote bags, as well as made into the shipping container itself, such as a picnic cooler or a medical transport case. The versatility of EPS foam lends itself to many other applications and is an excellent choice for many projects.
