Functionality: The machine heats polystyrene beads, causing them to expand. This process can involve multiple stages to achieve the desired density and expansion ratio.

Steam and Temperature Control: Precise control of steam pressure and temperature is crucial for consistent expansion and quality of the final product.

Production Efficiency: Modern EPS pre-expanders are designed for high efficiency, allowing for continuous operation and rapid production cycles.

Versatility: They can produce various densities of EPS, catering to different industrial needs.

Environmental Considerations: Some models are designed to minimize energy consumption and reduce emissions, aligning with sustainability goals.

Applications:

Packaging: EPS is commonly used for protecting fragile items during shipping.

Insulation: Used in building materials for thermal insulation.

Construction: Lightweight concrete and other composite materials.
