  • Patent number: 11485816
    Abstract: Flexible polyurethane foams are made by reacting a hydrophilic quasi-prepolymer, water and a polymer polyol in the presence of a silicone surfactant and an ethylene oxide/higher alkylene oxide block copolymer. The foams exhibit desirably low densities and compression sets, and have good thermal and moisture-wicking properties. The foams are useful in bedding and other comfort applications in which they are exposed to body heat and bear at least a portion of the weight of the user. The thermal and moisture wicking properties contribute to perceived comfort for the user.

  • Patent number: 10844218
    Abstract: Moisture-curable resin compositions include a mixture of one or more polysilylated of ethers and one or more polyether monosilanes. The polyether monosilanes have one hydrolysable silane group per molecule, and the hydrolysable silane group has at least two hydrolysable substituents. The polyether monosilane is an effective plasticizer and viscosity reducer. Despite the presence of the polyether monosilane, the resins compositions cure to form cured sealants having useful tensile and elongation properties.

  • Patent number: 10160830
    Abstract: An alkylene oxide mixture containing greater than 50% by weight ethylene oxide is continuously polymerized in the presence of a double metal cyanide polymerization catalyst and certain magnesium, Group 3-Group 15 metal or lanthanide series metal compounds. The presence of the magnesium, Group 3-Group 15 metal or lanthanide series metal compound permits the polymerization to be performed continuously without premature deactivation of the double metal cyanide catalyst.

  • Patent number: 9290605
    Abstract: Flexible polyurethane foams are made using certain hydrolysable silane compounds in the foam formulation. The hydrolysable silane compounds contain at least one isocyanate-reactive group and at least one hydrolysable silane group. The presence of the hydrolysable silane compound in the foam formulation leads to improved tensile, tear and elongation properties without an adverse effect on other important foam properties such as resiliency and hysteresis loss.

  • Patent number: 9181428
    Abstract: Moisture curable compositions including silylated polymers and methods for producing the same are provided. A two component moisture curable system for producing a cured or cross-linked silylated polymer having improved compression set properties is provided. The two component system comprises a first formulation and a second formulation. The first formulation comprises a silylated polymer, water, and filler and the second formulation comprises the silylated polymer, a curing catalyst comprising at least one Brønsted acid, and a moisture scavenger. The final cured formulation may have a compression set, determined by ASTM D395 or ISO 815-1, of less than 100%, and in some examples less than 50% and in some examples less than 15%. This demonstrated improvement in compression set not only allows the silylated polymers to be used in applications where cyclic loads are applied but also enhances product durability.
