What This Grade Solves

Production problems eliminated by this raw material grade — with engineered, measurable solutions.

The Problem 1

Standard EPS beads cannot achieve density below 8 kg/m³ — limits product cost optimization for low-density applications

How This Grade Solves It

High-expansion beads achieve 4-8 kg/m³ density for super-light packaging — 40-50% lighter than standard insulation grade.

The Problem 2

Lightweight packaging customers (fish boxes, large protective inserts) need lowest possible density for shipping cost optimization

How This Grade Solves It

High-expansion variant cuts material cost per unit volume by 30-40% — directly improves margin on low-density products.

Engineered Performance Advantages

Every advantage backed by measurable specs — no marketing claims without data.

Expansion Ratio

70-100×

vs standard 40-80×

Higher expansion = lower density = lower material cost per unit volume.

Target Density

4-12 kg/m³

vs standard 8-30

Lowest densities for super-light packaging.

Material Cost Savings

30-40% per unit volume

vs standard density

Direct margin improvement on low-density products.

Real Production Applications

See where this grade fits in real factories.

Ultra-light EPS packaging insert and cushioning for fragile goods

Industrial cushioning for electronics and high-value goods

Low-density fruit and produce packaging crates

Bulk EPS blocks for export packaging production

Build a Complete EPS / EPP Line

This raw material grade fits into the full ChinaEps supply chain — machinery, complementary grades, and turnkey lines from one supplier.

Downstream — Finishing & Packing

PE Pre-Expander

Specialized recipe required for high-expansion processing.

SM Shape Molding

Low-density beads work best with shape molding for finished packaging products.

Product FAQ

The questions buyers ask most often before placing an order.

What's the trade-off vs standard grade?

Lower compressive strength (50-90 kPa vs 100-200 kPa). Suitable for packaging and unloaded insulation; not for structural or load-bearing applications.

Compatible with FR additives?

Limited — FR additives reduce expansion ratio. For FR low-density needs, use specific FR variants.

Shelf life?

9-12 months — slightly shorter than standard due to higher pentane content for expansion.
