Expanded Polystyrene Products - The Closest Thing to 100% Natural
Expanded polystyrene products are made of raw materials that are entirely recyclable as well as biodegradable. EPS is what we generally refer to as foam. Foam means to expand. Expanded polystyrene is basically 98% air and the remaining is polystyrene plastic which is a hydrocarbon. There are several forms of foams that enlarge to more than 50% of its original size when reacted with a blowing agent (usually a gas such as pentane or butane). Depending on the base plastic and the blowing agent, foams are classified into different categories and EPS or expanded polystyrene products are one of them. How Expanded Polystyrene is Created? Polystyrene begins its journey rather humbly. Styrene is a liquid, which is immiscible with water. Water and styrene are mixed in a 2:1 ratio and agitated severely to produce very small and lightweight beads. These beads are produced in large mega gallon reactors. The beads are then transferred to foam producing factories where they undergo the proc...
