Provided is a polyurethane foam having excellent heat resistance and the like. The polyurethane foam is obtained from a material that contains a polyol and a polyisocyanate, in which the polyol contains a polyester polyol, the polyisocyanate contains a diphenylmethane diisocyanate-based isocyanate, it is preferable that the polyester polyol has one or more side chains composed of an alkyl group, and the polyurethane foam may be used as a soundproof material for vehicles.

This invention relates to hybrid polyols useful in the manufacture of polyurethane. The hybrid polyols of the present invention is derived by copolymerizing or grafting a traditional polyester polyol onto a natural oil polyol. In the preferred embodiment of the present invention, the traditional polyester polyol grafted onto natural oil polyol contains a high level of bio-renewable content. The hybrid polyols of the present invention with high level of bio-renewable content is useful in the manufacture of polyurethane either alone or in combination with polyester polyol or polyether polyol derived from petrochemical sources.

Acoustic dampeners, methods of making acoustic dampener, and uses thereof are described. The acoustic dampener includes a polymer foam article; and a metal-organic framework portion. The metal-organic framework portion comprises a metal-organic framework in a polymer matrix. The metal-organic framework portion is adhered to, or otherwise coupled to or included with, the polymer foam article. Such an acoustic dampener can be used in a computer equipment cabinet.

Provided is a flexible polyurethane foam having high hardness required for weight reduction of members and having low stress relaxation. A flexible polyurethane foam comprises a structural protein fiber having a length of 0.1 mm to 5 mm.

According to one embodiment, a sound absorbing urethane foam is provided. In the sound absorbing urethane foam, a normal incidence sound absorbing coefficient at a time when a diameter is 29 mm and a thickness is 10 mm is 40% or more in an entire range of frequencies of 1000 Hz to 3150 Hz.

A polyurethane foam is disclosed having unique load bearing characteristics rendering it suitable for a variety of applications. The foam exhibits high surface-softness and smoothness properties, making it well-suited for use in articles such as pillows and mattress toppers. However, upon continued application of pressure, the resilience of the foam increases sharply, translating into a remarkable support characteristics that make the foam suitable for use in the seat portions of chairs and sofas, as well as in the base portion of mattresses. The foams therefore address the limitations of conventional, high-resilience and visco-elastic polyurethane foams. A process of making the foam and its use in various articles is also disclosed.

The present invention relates to bead foams made of thermoplastic polyurethane and styrene polymer with a modulus of elasticity below 2700 MPa, to moldings produced therefrom, to processes for the production of the bead foams and moldings, and also to the use of the moldings for shoe intermediate soles, shoe insoles, shoe combisoles, cushioning elements for shoes, bicycle saddles, bicycle tires, damping elements, cushioning, mattresses, underlays, grips, protective films, in components in the automobile-interior sector or automobile-exterior sector, balls and sports equipment, or as floorcovering.

Bead foams made of thermoplastic polyurethane and polypropylene(s), moldings produced therefrom, processes for the production of the bead foams and moldings, and uses of the moldings in shoe intermediate soles, shoe insoles, shoe combisoles, cushioning elements for shoes, bicycle saddles, bicycle tires, damping elements, cushioning, mattresses, underlays, grips, protective films, in components in the automobile-interior sector or automobile-exterior sector, balls and sports equipment, or as floor covering, may be based on composition with (a) 60 to 90 wt. % of thermoplastic polyurethane as component I, (b) 10 to 40 wt. % of polypropylene as components II, where the entirety of components I and II provides 100 wt. %.

A damping-enhanced pressure-sensitive adhesive comprising a pressure-sensitive adhesive and a at least one damping additive. The pressure-sensitive adhesive comprises a silicone-based polymer and optionally, at least one catalyst and/or at least one initiator.

Provided herein are architectural coating compositions having sound-reducing properties. The coating compositions comprise a high-density pigment component. Preferably, the high-density pigment component has a density of at least about 3 grams/cm.sup.3. In one embodiment, the high-density pigment component comprises barium sulfate.
