What This Machine Solves

Three production problems eliminated by this machine — with engineered, measurable solutions.

The Problem 1

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

How This Machine 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 Machine 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.

Real Production Applications

See where this machine fits in real factories.

Class B1 flame-retardant EPS for high-rise residential and commercial buildings

Hospital, school, and government building facade insulation per fire code

External wall insulation system (EWI / ETICS) with FR certification

Premium FR insulation board production for EU and Russian markets

Build a Complete EPS / EPP Line

This machine integrates into the full ChinaEps production flow — upstream, downstream, and auxiliary equipment from one supplier.

Downstream — Finishing & Packing

PE-1800 Premium Pre-Expander

Required for FR-grade at production scale due to ATEX zone-22 dust requirements.

SPQ-FR Cutting Line

Purpose-built cutting for graphite/FR-EPS production.

Auxiliary Systems

Graphite-FR Variant

For premium thermal performance + fire rating, use mat-graphite which combines both properties.

Equipment Investment

~$1,400-1,600/ton FOB illustrative (quote-specific)

Payback Period

Required premium for fire-code compliant production — premium contracts pay 2-3× the standard insulation margin

Throughput

25kg bags or 1,000kg jumbo bags with COA + fire-test reports

Product FAQ

The questions buyers ask most often before placing an order.

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.
