  • Patent number: 10087277
    Abstract: Polyurethane foam is formed by foaming raw materials that includes either an aliphatic isocyanate or a melamine derivative, a urethane emulsion, and an anionic foam stabilizer. The compression set (JIS K6401) of the polyurethane foam, specifically, the compression set (JIS K6401) after the polyurethane foam being allowed to stand for 22 hours in a state of 50% compression under condition of 70° C., is 40% or less. By this, it is possible to obtain polyurethane foam that is low density, pliable and resistant to collapse, i.e., polyurethane foam having high recovery properties.

  • Patent number: 10077331
    Abstract: A polyurethane filter foam is provided herein. The polyurethane filter foam may have improved permeability by having both a small cell and a large cell in a range for maximizing the opening property of the foam. In some instance, this is achieved by specifically configuring and foaming a composition of polyether polyol and methylene diphenyl diisocyanate (MDI) to manufacture the polyurethane foam. The polyurethane foam of the present invention can be manufactured without performing a reticulation process.

  • Patent number: 10040223
    Abstract: Methods and combinations of a curing catalyst with a mold release mixture, which is then subsequently applied to the surface of a mold prior to the application of polyurethane reactants to said mold, where the curing catalyst component has the effect of catalyzing the reaction at the surface of the molded part. This catalysis results in greater reactivity at the surface between reacting portions and lower delamination of the surface of the foam, thereby leading to more attractive skins with a more consistent cell structure, and lower de-mold times due to skins whose nature makes them less likely to adhere to the surface of the mold. These foams will be less likely to tear upon opening of the mold, and production quality and output will be improved.
