A bearing laminate can include a metal support layer, a foam layer overlying the metal support layer, the foam layer including a polymeric foam; and a sliding layer overlying the polymeric foam layer, the sliding layer comprising a polymer matrix. Bearing articles made from the bearing laminate can have exceptional damping properties, such as a high damping ratio combined with a low dynamic stiffness.

The present disclosure relates to methods of making an article comprising PTFE, methods of making expanded articles comprising PTFE, articles comprising PTFE, and expanded articles comprising PTFE having improved mechanical and electrical performance and particularly reduced variability in mechanical, electrical and dimensional properties, particularly over long lengths.

Articles containing PTFE having improved dimensional stability particularly over long lengths, methods for making such articles, and cable/wire assemblies containing such articles

A polymer sheet includes a polyurethane core. The polyurethane core has a first major surface and a second major surface opposite the first major surface. The polymer sheet can have at least one functional layer overlying a major surface. The polymer sheet has a thickness t. The polyurethane core has a thickness t. In embodiments tcan be at least 0.3 t. The polyurethane core can have at least one of the following property: (i) a Scratch Resistance Rating, as further described herein, of not greater than about 10 wt %, (ii) an elongation at break of at least 200%, (iii) a tensile strength at break of at least 0.3 MPa, (iv) a loss of tensile strength of not greater than about 30% when exposed to UV light according to standard SAE J1960 (Rev. August 2003). The polymer sheet can be used for gaskets or bonding tapes.

An acoustic damping article includes a substrate, wherein the substrate has a surface area S. The acoustic composition further includes a polymer resin. The polymer resin coats partially the surface area with a set of areas. The ratio of the coated areas over the surface area S is less than 1 and the polymer resin coverage is not greater than about 500 g/m. Embodiments of the present disclosure include an acoustic damping article including a release liner; and an acoustic damping composition disposed on the release liner. The acoustic damping composition partially coats the release liner, and the acoustic damping composition has a Patterned Interlayer Stiffness of at least about 1 GN/m.

A sealing gasket includes a liner and a polyurethane foam layer disposed on the liner. The polyurethane foam layer can have a density of 50 kg/mto 250 kg/m, a force-to-compress at 25% compression of not greater than 5.0 psi, and an 50% springback parameter of not greater than 2.0 seconds. The polyurethane foam has a thickness in a range of 0.3 mm to 10.0 mm. A surface of the polyurethane foam layer has a skin.

The subject of the invention is a water-impermeable flexible polyurethane foam obtained by reacting a polyol component, which comprises at least one hydrophobic polyol, with a polyisocyanate component in the presence of a foaming agent, characterized in that it has a compression force of less than or equal to 12 kPa for 50% compression. Advantageously it has a density not exceeding 150 kg/m, preferably not exceeding 60 kg/m. The foam may be obtained by a cast-foam manufacturing process or by molding. It can be used as a water-impermeable seal.
