What This Grade Solves

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

The Problem 1

Standard EPS fails fire-code requirements for high-rise residential, commercial, and government buildings

How This Grade Solves It

Flame-retardant (FR) EPS beads meet Class B1 fire rating per EN 13501-1 — required for any building above 22m in Europe and many other markets.

The Problem 2

FR retrofit additives applied post-production produce uneven distribution + reduce expansion

How This Grade Solves It

Factory-blended FR beads have additives uniformly distributed throughout the bead — consistent fire performance batch-to-batch.

Engineered Performance Advantages

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

Fire Rating
Class B1 (EN 13501-1)
vs standard EPS = Class E

Required for buildings >22m and many commercial applications.

Self-Extinguishing Time
<15 sec
vs standard EPS = burns continuously

Stops fire propagation when ignition source removed.

Smoke Density Limit
s2 class
vs standard EPS = s3

Lower smoke emission for occupant safety during fires.

Product FAQ

The questions buyers ask most often before placing an order.

Which flame retardant grade EPS bead should I choose?
Match the grade to your target block density: F-301/F-302 (12-16 g/L) suit standard insulation boards, F-303/F-401 (15-25 g/L) suit structural ICF and facade panels, and F-501 (25-30 g/L) suits high-density fire-rated applications. All five grades carry the same Class B1 (EN 13501-1) fire rating — the grade only changes bead size and expansion ratio, not fire performance.
Which FR additive — HBCD or polymeric?
Polymeric FR (HBCD-free) — meets REACH regulations and current EU environmental requirements. Avoids the 2014+ HBCD phase-out issues.
Compatible with standard pre-expanders?
Yes for standard PE-1200/1400. For FR-grade at scale (>1,000 t/year), upgrade to PE-1800 with ATEX-compliant handling.
Fire-test report included?
Yes — each shipment ships with EN 13501-1 test report from accredited European lab. Required for building inspector approval.
