In manufacturing, EPS stands for Expanded Polystyrene, a versatile lightweight foam material created by expanding polystyrene beads using steam and pressure. This rigid, closed-cell foam is widely used in packaging, construction insulation, and product manufacturing due to its excellent thermal insulation properties (R-value of 3.6-4.2 per inch), light weight (typically 1-2 pounds per cubic foot), and cost-effectiveness (20-30% less expensive than alternative materials).

EPS and EPP machines are specialized equipment designed for processing different types of foam materials used in packaging, automotive, construction, and consumer goods industries. The main differences between EPS Machine and EPP Machine systems lie in their operating parameters, processing capabilities, and end applications.
