  • Publication number: 20200325268
    Abstract: Disclosed is a method for producing an open cell low-density semi-rigid polyurethane foam suitable for general use as a thermal insulating material and/or acoustical applications. The method comprises producing a flame-retardant open-celled semi-rigid polyurethane foam having an overall density of 5 to 30 kg/m2 by reacting (a) a polyisocyanate and (b) a polyol having a molecular weight of 100 to 10,000, in the presence of (c) 2,2-bis(chloromethyl)-trimethylene bis(bis(2-chloroethyl)phosphate, (d) blowing agent, and (e) optional additional components.

  • Publication number: 20180319926
    Abstract: The present invention relates to a reactive formulation used to make a polyurethane foam which is particularly suited for use in under the hood vehicle applications which require sound deadening and vibration management and a process to make said foam. In particular, the polyurethane foam is made from a reactive formulation comprising an A side comprising (i) one or more organic isocyanate and a B side comprising (ii) one or more isocyanate-reactive component, (iii) a carbon nanofiller; and (iv) one or more additional component selected from a catalyst, a blowing agent, a cell opener, a surfactant, a crosslinker, a chain extender, a filler, a colorant, a pigment, an antistatic agent, reinforcing fibers, an antioxidant, a preservative, or an acid scavenger.

  • Publication number: 20180148535
    Abstract: The present invention discloses a tertiary amine initiator and polymeric polyol compositions made therefrom useful for making polyurethane polymers, especially polyurethane foams. Said polyurethane polymer foams demonstrate a good balance of mechanical properties, physical properties, and low emissions. The tertiary amine initiator is one or more partially alkylated amine compound have the Structure II: RR1N—(R?—NH)y—(R?—NR4)x-y—R?—NR2R3 wherein R? is a C1 to C6 linear or branched alkyl group, R, R1, R2, and R3 are independently a hydrogen or a C1 to C6 linear or branched alkyl group with the proviso that at least one of R, R1, R2, and R3 is not hydrogen, R4 is a hydrogen or a C1 to C6 linear or branched alkyl group, x is from 1 to 33, y is from 0 to 32, and z is from 0 to 15, with the proviso that x-y is equal to or greater than 1 and the number of N—H bonds in (II) is greater than 0 and less than 8.

  • Patent number: 9751284
    Abstract: Skinned composites contain a plasticized polymer skin layer adhered to a layer of a polyurethane. The polyurethane is made from a reaction mixture that contains specified amounts of a polyester polyol and an acidic material. The presence of both the polyester polyol and acid leads to significantly improved adhesion between the polyurethane and skin layer. The invention is particularly useful when the skin is highly plasticized.

  • Patent number: 9517607
    Abstract: PVC-skinned composites include a substrate, a skin and an intermediate polyurethane layer. The polyurethane layer is characterized in having a low molecular weight between crosslinks, i.e., is somewhat highly crosslinked. The high level of crosslinking in the polyurethane leads to improved performance of the skin layer. The skin layer retains its original color upon aging, is less prone to shrinking and other loss of physical properties, and adheres better to the polyurethane layer.

  • 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.
