Frequently Asked Questions about TUNHE Expandable Polystyrene
Minimum order quantity is from 1 bag (25 kg) or 1 pallet (840–1,000 kg). Direct full truckload and railcar shipments are available for manufacturing plants.
Pricing depends on particle fraction (201, 301, 401), order volume, and destination warehouse. Contact our sales department for an official formal quote.
Shipments can be handled via customer pickup or organized turnkey by Polymer Systems LLP with prompt dispatch to all regions of Kazakhstan.
TUNHE EPS consists of spherical polystyrene beads containing pentane blowing agent. Upon steam heating, the beads expand up to 40–50 times their original volume.
Primary applications include building thermal insulation boards (EPS), insulated concrete forms (ICF), protective molded packaging, and sandwich panels.
They differ by bead diameter: 201 (1.0–1.6 mm) for low-density block molding; 301 (0.7–1.0 mm) for standard facade boards; 401 (0.4–0.8 mm) for high-density packaging and ICF.
Choose grade 201 for low density blocks (10–14 kg/m³), grade 301 for standard exterior wall insulation, and grade 401 for precision molded packaging.
The F suffix indicates flame retardant additives. The finished foam self-extinguishes immediately once the open ignition source is removed.
Beads contain 5.5–6.5% pentane blowing agent, ensuring high expansion ratio and rapid cycle times.
Under controlled steam pre-expansion, beads expand 30 to 55 times, yielding finished densities between 9 and 35 kg/m³.
Low thermal conductivity (λ ≈ 0.036–0.038 W/m·K), uniform cellular structure, minimal water absorption, and self-extinguishing safety.
Packed in 25 kg multi-layer gas-barrier kraft bags with foil inner lining or heavy-duty 840–1,000 kg moisture-proof octabins.
Available with certified manufacturer warranty from Polymer Systems LLP regional warehouses in Almaty, Karaganda, and Shymkent.
