EPS is unique in its ability to be small in particle size, low in density and very efficient as a volume filler on a cost per volume basis! For the filling or re-filling of neck pilows and soft toys MicroBead Expanded Polystyrene (EPS) Fire retardent beads are sized at 1. The primary functions include pre-expansion, molding, and insulation material production—each stage critical to achieving consistent, high-performance EPS output. 5 – 2mm diameter with a nominal density 23kg/m3 sold in bags of 0. Ideal for high‑grade insulation and complex molding. 142 cu/m (5 cubic ft. 5 days ago · The expanded beads are blown into a mold by reheated steam, causing the beads to expand by 10% of their size. After a settling process, the desired custom EPS shape is created according to your design specifications. What is expanded polystyrene? Expanded Polystyrene (EPS) is a type of rigid foam plastic that is derived from polystyrene beads. ) sized at 600mm diameter x 600mm high. EPS is sup- product manufacturers and catalogue and plied to molders in the shipping companies. For bean bags, 15–20 g/L is typical; for weighted blankets, higher density may be preferred. EPS Pre-Expander – The Starting Point of Production The EPS pre-expander is the core machine in any EPS factory. This property enhances their suitability for applications where weight is a concern, such as packaging and insulation. 3 days ago · Density: Measured in grams per liter (g/L), density affects how firm the final product feels. Lightweight EPS is form of a polystyrene ideal for these packaging applications bead; EPS beads are due to its physical properties, in particu-loaded with a blowing lar its cushioning characteristics, dimen-agent, usually pentane, sional stability and its thermal and mois-and other The raw EPS beads (EPS= expandable polystyrene) are delivered at a density of about 38 #/cubic foot in a wide range of initial sizes (10 to 80 mils diameter) The smallest beads give the best fill into the tool and surface finish, but they are more difficult to control for uniform density. Nov 17, 2025 · Despite their small size, EPS beads exhibit minimal density, making them easy to handle and transport. Feb 18, 2026 · Types of China EPS Foam Block Moulding Machines An EPS (Expanded Polystyrene) foam block moulding machine is a vital piece of equipment in the manufacturing of lightweight, insulating, and protective foam products. Feb 18, 2026 · An EPS machine facilitates the precise expansion and molding of polystyrene beads into finished products through controlled thermal and mechanical processes. Smaller beads generally produce higher-density EPS, which results in greater mechanical strength and durability. They are compatible with many antistatic agents, mineral oils, color pigments and other additives, which can be added during the transformation process. gdnwdakytcpnqutwmgyeoarhhpvzqnsaerigalqmzfdcx
