E-grade standard EPS is a general-purpose material for molded foam and panel production. It offers a high expansion ratio, even bead expansion, dependable bonding and a uniform surface finish. The grade range supports different bead sizes and finished-product densities.
E-grade standard EPS is used for EPS foam panels, expanded-polystyrene bead-board panels and molded foam products. High expansion, good bead bonding and a uniform finish support repeatable production.
The E101 to E601 range provides bead-size options from 1.20–1.80 mm down to 0.30–0.50 mm. General-purpose, fine-bead and pattern-grade selections suit different density and surface-detail requirements.
| Grade | Application / positioning | Molded density (kg/m³) | Bead size (mm) | Thermal conductivity λ (W/m·K) |
|---|---|---|---|---|
| E101 | Standard General-Purpose | 12–25 | 1.20–1.80 | 0.036–0.041 |
| E201 | High-Density Standard | 15–30 | 0.90–1.40 | 0.036–0.041 |
| E301 | Ultra-Fine Bead | 15–30 | 0.75–1.10 | 0.036–0.041 |
| E401 | Micro-Fine Bead | 15–30 | 0.65–0.90 | 0.036–0.041 |
| E501 | Micro-Bead Ultra-High-Density | 17–35 | 0.50–0.80 | 0.036–0.041 |
| E601 | Ultra-Fine Pattern Grade | 19–45 | 0.30–0.50 | 0.036–0.041 |
