Description
Rokopol GS364 is a low-reactive polyether sucrose polyol that is used in the production of rigid and semi-rigid polyurethane (PUR) foam in reaction with isocyanate. The product is in the form of a homogeneous, clear liquid, from yellow to dark brown. It contains antioxidants (excluding BHT). The product is characterized by medium viscosity in the range of about 2000 – 4000mPas with relatively high nominal functionality f = 4.5. Rokopol GS364 is a product designed for the production of PUR polyurethane systems with moderately low viscosity and low hydroxyl value, which reduces the consumption of PMDI. Relatively high functionality allows the use of an increased water content in the designed PUR systems, and also ensures good flow during the foaming process. Rokopol GS364 improves mechanical properties of foam, compared to typical sucrose/glycerine based polyetherols. The product ensures long gel time for PUR foam systems, which makes it possible to apply it to PUR rigid foam block systems. The product is used in combination with other polyols and additives to modify the properties of the PUR system, in particular: viscosity, reactivity, gel time, degree of cross-linking. The product also influences the properties of the final rigid foam, such as adhesion to various surfaces, flame retardancy, hardness, abrasiveness, closed cell content (insulating power), etc. Main application advantages of Rokopol GS364: ensures fluidity during the foaming process of rigid foam, thanks to the physicochemical properties of the polyol, the foam is characterized by improved mechanical properties, enables modifying the properties of the PUR system due to compatibility with other polyols and additives, the product provides long gel time of PUR foam. The most common applications of Rokopol GS364: closed-cell foams used for thermal insulation in refrigeration (in particular refrigerators, freezers), closed-cell foams used for thermal insulation for higher temperatures: boilers, flood systems, pre-insulated pipes, PUR sandwich panels, 2K spray foam systems, closed-cell PUR foam for thermal insulation in construction, specialized small-scale applications, including rigid moulded foam (e.g. imitation wood, fishing lures – wobblers). Products made on the basis of Rokopol GS364 are of exceptional quality. Thanks to the refined production process, the polyol has excellent parameters, not only in PUR systems.
Properties and applications:	product intended for the production of PUR systems; the possibility to modify the properties of the PUR system thanks to the use of the product together with other polyols; very high quality of the final product due to the physicochemical properties of the polyol; used in closed-cell foams for insulation in refrigeration systems and for higher temperatures; used in 2K foam spray systems; the product has excellent mechanical parameters;
