A bead foam which is utilized in the applications such as industrial and automotive packaging is known as expanded polypropylene foam. This foam shows unique and exceptional properties like impact resistance, thermal insulation, water & chemical resistance and outstanding energy absorption. Owing to its unique abilities of cushioning and its flexibleness that offers tremendous protection to composite shapes, automotive expanded polypropylene foams are widely used in industrial packaging. There are basically two types of automotive expanded polypropylene foams such as low and high density expanded polypropylene foams which are available in various densities. An expanded polypropylene foam with high grade density displays outstanding strength and reduced property of weight. These foams are utilized in application where the critical parameter is the management of energy. This is the precise reason that such foams are used in automotive applications such as bumpers and other passenger safety parts. On the other hand low density foams are utilized in the applications such as industrial packaging, while medium density foams are applicable to furniture and other consumer products.
