EPS Resin Grades

General-purpose, flame-retardant and customized grades — matched to your end product and molding process.

General Purpose

Grade H

Blowing agent 6.5–7.5% · expansion 40–200×

  • Suitable for multi-pass (secondary) foaming
  • Fast foaming speed, superb fusion at ultra-low density
  • Lightweight boards, cut sheets, lost-foam, light packaging
General Purpose

Grade E

Blowing agent 5.5–7.0% · expansion 15–125×

  • Wide molding window, excellent fusion strength
  • High surface finish on molded parts
  • Appliance packaging, fish boxes, buoys, sports protection
General Purpose

Grade B

Blowing agent 5.0–6.5% · expansion 10–100×

  • Fast cooling & demolding — short cycle time, low energy
  • Ideal for high-volume packaging lines
  • Appliance packaging and general packaging parts
Flame Retardant

Grade F

Blowing agent 5.5–7.0% · expansion 15–125×

  • Self-extinguishing molded products
  • Can be multi-pass foamed for boards
  • Building insulation, electrical structural parts
Flame Retardant · B1

Grades FM / FG

Blowing agent 4.5–6.5% · expansion 20–60×

  • Oxygen index up to ≥ 35, fast OI rise
  • FG: grey bead, even lower thermal conductivity
  • External wall insulation (ETICS), sandwich panels
Flame Retardant

Grade FL

Blowing agent 3.5–5.0% · expansion 20–50×

  • Low pentane — faster molding, higher productivity
  • Rapid oxygen-index development after molding
  • Building insulation boards

Customized grades also available on request: FD food grade · NP impact-resistant · KF filler grade · R color · D anti-static (10⁹–10¹¹ Ω) · RD eco grade · KD cup & bowl · H-4S lost-foam casting · E/B-4S bean-bag filler.
