I'm making a new seat cushion, imagine a custom wheelchair seat cushion. The design phase is mostly done; the production process development phase is underway. We will be growing volumes from zero. I need a flexible polyurethane foam formulator with good knowledge of the current state of the art and of wholesale suppliers, to specify a formulation and connect with suppliers to optimize specifications and cost. Hopefully we can choose a flexible polyurethane foam formulation with integral skin, sufficient softness, and sufficient structural support. (See [login to view URL] for my state of current knowledge about foams.) Alternatively we can mold part of the product for the structure, and use cut sheet form for part of the product for softness, and put it together in a sewn fabric cover, separating those three requirements and therefore likely to achieve each requirement, but that is likely to be much more expensive in unit labor costs. So this Freelancer project is to specify a formulation for the specs I'll tell you about, such that suppliers will give reasonable prices for the ingredients and the production process can be cost-optimal.
