  • High resiliency polyurethane foams
    Patent number: 4108791
    Abstract: Flexible polyurethane foams are prepared from polyols containing 0.1 to 5.0 percent by weight of an inorganic filler such as fumed silica having a pH value of 6-8.5 and an effective particle size of less than 7 microns. Foams molded from such polyols exhibit in some instances an improvement in some of the strength properties and do not alter substantially, the mold fill time. In addition, there is an improvement in foam porosity (air flow) as well as a reduction in the force required to crush foam articles.

  • Imparting anlsotropy to foams by orienting added fibers whereby said fibers become parallely aligned
    Patent number: 4102831
    Abstract: This invention relates to a method of imparting anisotropy to polymeric foams and to the resultant products. By this invention enhanced mechanical properties are produced in polymeric foams such properties being, for example, compressive yield strengths, modular tensile strengths, and the like. Importantly, other properties of enhanced value are achieved, as for example, improved thermal conductivity and enhanced burning rates.The process involved comprises mixing in liquid form various components of the foam which is to be produced in a foaming step which involves the action of the components in the presence of a foaming agent that effects the foam expansion, and mixed with these liquid mixtures is a low level concentration of relatively short fibers, one-half inch or less, the fibers being made from either an inorganic or organic material with fiber glass or aluminum fibers being preferred.
