Embodiment Construction

[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...

Abstract

A foam article, for use in a seat such as a seat cushion, includes an open cell, polyurethane foam material that includes a plant oil-based polyol material content greater than five percent and is produced from the reaction of a base polyol including at least a portion of a plant oil-based polyol, a copolymer polyol including at least a portion of a plant oil-based polyol, water, a cross-linking agent, and a surfactant that are reacted with an isocyanate material for producing the seat cushion having performance specifications that are equivalent or better than the performance characteristics for a traditional petroleum oil-based polyol material seat cushion.

Description

[0001] Cross-references to related patent applications [0002] This application claims priority to US Provisional Application No. 60 / 855,153, entitled "Non-Petroleum Based Polyol Foam Products," filed October 30, 2006, which is incorporated herein by reference in its entirety. Background of the invention [0003] The present invention relates to open cell polyurethane foam parts having non-petroleum based polyol materials and methods of making products comprising said open cell polyurethane foams. In particular, the present invention relates to open-cell polyurethane foam formulations having vegetable oil-based polyol moieties and petrochemical-based polyol moieties, and to a method for preparing foam articles with improved performance indicators as cushioning materials in seating applications method. [0004] It is known to provide foam cushioning to comfort the occupant of a seat, whether the seat is a piece of furniture, an instrument or a vehicle such as an automobile. ...
