Panel insulation systems

Polyurethane Systems for Cold Room Panel
and Sandwich Panel Manufacturing

Two-component rigid polyurethane systems for sandwich panel manufacturing, cold room panels and refrigerated truck bodies, suitable for panels 4 to 20 cm thick. We formulate them in Bursa, Türkiye, and adapt each one to your continuous or press line and your facings.

Technical overview

How polyurethane systems are used in sandwich panel manufacturing

The polyurethane core of a cold room or sandwich panel is formed from a two-component rigid polyurethane system: a polyol blend and an isocyanate are mixed and poured or injected between the two facings, where the foam expands, fills the space between them and cures. Two groups in our rigid systems range are used for this. Our cold-room panel systems were developed first for cold room panels and refrigerated truck-body panels, and are also used in industrial coolers and refrigerators. Our refrigerator systems work the other way round: they were developed first for refrigerators and industrial coolers, and are also used for panels. Both groups cover insulation thicknesses from 4 to 20 cm, bond well to the facings and fill the cavity evenly, without voids. The cold-room panel system also comes in a flame-retardant version that reached B1 in laboratory fire testing. Which group fits depends on what you make most; if one line makes both panels and appliances, tell us.

The systems run on continuous panel lines, which usually suit high-volume production, and on discontinuous press lines, which usually suit smaller batches and special sizes. For refrigerated truck bodies, you can use panels made with the cold-room panel system, or block-pour the complete box with the separate systems we have developed for that job. The blowing agents are ozone-friendly, from the n-pentane, HFC and HFO families, and none of our systems contain HCFC-141b. We agree the blowing agent with you so that it suits your plant's equipment and the regulations in your market. For press lines and moulds, we also make our own mould release agents in-house, both water-based and solvent-based, so you can source the release agent and the system from one supplier.

We match the system to your panel and your line rather than picking it from a catalogue. The line type, panel thickness, facing materials, the fire class your panel must reach, your foaming equipment and your market all shape the choice. From there we adapt one of our own formulations to your process, drawing on more than 700 existing formulations. For suitable projects, our technical team can visit your line and run production trials with you.
