EPS Raw Material — P Grade
P-grade ultra-light EPS is designed for lightweight packaging, including protection for fragile items such as ceramic lamps. It combines high foaming efficiency, shock absorption, good toughness and a smooth surface. Its storage stability and pre-expansion flexibility support a range of molded packaging shapes.
Lightweight Fragile-Item Packaging
P-grade EPS is intended for packaging that protects fragile products while keeping weight low. Typical uses include protective boxes and inserts for ceramic lamps and other easily damaged items.
Product Features
- Ultra-light packaging
- Shock absorption
- High foaming efficiency
- Good storage stability
P-Series Expansion and Density
The P101 to P501 range includes bead-size options from 1.30–1.60 mm down to 0.35–0.50 mm. It combines high foaming efficiency, good toughness, smooth surfaces and storage stability for varied packaging forms.
