Production Options


STYROFOAM™ extruded polystyrene foam panels are produced with a flat, dust-free surface and narrow tolerances. Hot-wire foam cutting equipment makes it possible to cut core layers of as little as 5 mm thick from STYROFOAM™ blocks.

Oscillating hot-wire cutting equipment can achieve a standard thickness tolerance of +/- 0.3 mm to +/- 0.5 mm (dependent on thickness), but there is also the option of manufacturing products as custom-made items with a thickness tolerance of +/-0.1 mm using a sander.

Dow is capable of manufacturing tailor-made products - requests for specific dimensions or particular tolerances should be arranged with the responsible engineer.

Production type Thickness tolerance
Online Standard  ± 0.5 mm
Close tolerance (CT)  ± 0.3 mm
Hot-wire cut (OF) (<15 mm)  ± 0.5 mm
(≥15 mm)  ± 0.3 mm
Quick sanded (QS) (≥10 mm)  ± 0.3 mm
Sanded (SA) (>10 mm)  ± 0.1 mm
(≤10 mm)  ± 0.3 mm

Panels with grooves can also be produced on request. Grooves may assist the bonding process by encouraging the expulsion of air and facilitating the even distribution of adhesive. (Standard grooves: 39 mm groove spacing; 3.5 mm deep, 1.8 mm wide.)

Solvent-free adhesives are ideal for bonding with outer layers made from aluminium, glass fiber reinforced plastic and wood, including common polyurethane adhesives (one component/two component adhesives as well as reactive hot melt adhesives). Various surface finishes are available to suit the particular bonding process.

In addition to processing using hot-wire equipment, STYROFOAM™ panels can be simply and cleanly cut using conventional tools and machines from the timber industry.
