SINTEPOL 1055 – polyoxypropylene triol, with a nominal molecular weight 1055. Contains a minimum amount of alkali metal cations through the use of modern purification technology. It is used in the production of one-component and two-component rigid polyurethane foam systems, which are used for the manufacture of mounting foams, polyurethane foam adhesives, rigid foams for target applications.
