[0045] Polyurethane-based foam pads can be formed according to a one-step process. In a one-step process, flexible and rigid polyurethane foams are usually made from a mixture of a first (or polyol) stream and a second (or isocyanate) stream. Polyurethane-based foams typically consist of a polyurethane-based base polyol resin, a polyurethane-based copolymer polyol resin (copolyol), water, a catalyst (or catalyst set), and typically an isocyanate such as toluene diisocyanate (TDI) or diphenylmethane- Composition of 4,4'-diisocyanate (MDI) or any blend of TDI and MDI and surfactant(s). The polyol material stream typically consists of polyurethane polymer and optionally propylene oxide (PO), which may be prepared using potassium hydroxide (KOH) and / or then capped with ethylene oxide (EO). Another method of preparing polyol materials involves the use of cobalt and zinc hydroxides, cesium hydroxide (CsOH), iridium hydroxide, and rubidium hydroxide (RbOH). The polyols can be prepa...
