INVESTIGATING THE EFFECTS OF WRESTLING GEAR IN FLATFOOT DEFORMITY OF WRESTLERS


Modyfication of the Rigid Polyurethane-Polyisocyanurate Foams

The effect of polyethylene glycol 1500 on physicomechanical properties of rigid polyurethane-polyisocyanurate (PUR-PIR) foams has been studied.It was found that application of polyethylene glycol 1500 for synthesis of foams in amount from 0% to 20% w/w had an effect on reduction of brittleness and softening point, while the greater the increase in
