Expanded Polystyrenes are highly versatile materials with diverse applications in different industries. They are water resistant, flexible and very light-weight. It is a practical option in for many industries because of its low cost and ease in handling. Flexible foams, for example, are good for absorbing external force; rigid foams provide strong resistance to fluid absorption. Expanded Polystyrenes are used as insulators that can serve as barriers to sound and vibration. It can also serve as thermal insulators due to its ability to control temperature-. Foams are used in construction, and as core materials for structural panels, columns, walls, and roofs. Because of foam’s buoyancy (especially closed cell foams), it is used in floating gear such as life jackets and other marine uses.
Expanded Polystyrenes are good protection for various items of different sizes and shapes. They are very popularly used in packaging due to their ability to absorb external pressures. They serve as cushions of different items especially breakable and fragile ones. Items inside them are very well protected to avoid damage during transit or storage. Polyethylene foams are good for packaging due to their versatility and resilience. Other uses of foams include thermal barriers for electronic gadgets, cushioning for seats, bedding and mattresses, filters, foundry and many others.
