About Expanded Polystyrene (EPS)
Polystyrene is one of the most widely used kinds of plastic. Polystyrene is a thermoplastic substance; it melts if heated and becomes solid again when cool.
EPS has been used for over half a century because of its technical versatility, performance, and cost-effectiveness.
EPS is an extremely lightweight material which is not surprising considering it is comprised of ~98% air. This characteristic makes it ideal for use in packaging.
