Rokopol® GS484 is a polyether sucrose polyol that is used in the production of rigid and semi-rigid polyurethane (PUR) foam in reaction with isocyanate. It exists in the form of homogeneous, clear liquid. It contains antioxidants (excluding BHT). It has average viscosity of 10 000 mPas at relatively high functionality f~4.5.
Rokopol® GS484 is dedicated to produce polyurethane PUR systems. Relatively high functionality allows using an increased content of water in the designed PUR systems. It allows obtaining better mechanical properties as compared to typical sorbitol polyethers. Ensures long times of gelation of rigid PUR foam systems, therefore it is used for block systems of rigid PUR foam.
Rokopol® GS484 is used in combination with other polyols and additives in order to modify properties of the PUR system, in particular: viscosity, reactiveness, gelation, degree of cross-linking. It influences also final properties of the rigid foam, such as: adhesion to various substances, hardness, flame retardancy, abrasion, content of closed cells (insulation), etc.
Main advantages of application of Rokopol® GS484:
physical and chemical properties of polyols increase mechanical properties of the manufactured foam,
compatibility with other polyols and additives enables modification of the PUR system’s properties,
ensures long gelation times of the PUR foam.
Most popular applications of Rokopol® GS484:
dedicated to 2C spray foam systems,
closed-cell foams used for thermal insulation in the refrigeration sector (in particular refrigerators and freezers),
closed-cell foams used for thermal insulation for higher temperatures (boilers, flow systems, pre-insulated pipes),
