Sintepol 1422

TU 20.16.40-006-06082157-2018

SINTEPOL 1422 – trifunctional high-molecular polyether, based on ethylene and propylene oxides, with a nominal molecular weight of polyether 4560. Contains a minimum amount of alkali metal cations due to modern purification technology. Used for opening pores or as base polyether in polyurethane foam systems designed for the production of soft (S), super soft (HS), high rubbery (HR), high visco-elastic (VE), standard (ST), elevated (high) rigidity (EL) molded and block foams.
