    Abstract: The foamed article is produced starting from a core layer (1) which comprises a flexible, open-cell foam having voids forming at least 90% of the volume of the open-cell foam. The core layer (1) is applied in a mold (6, 8), optionally together with an upper (3) and/or a lower cover layer (2), between a lower (5) and an upper mold surface (9) thereof. The mold (6, 8) is closed and a curable, foamable composition (7) is allowed to foam in the mold to produce a further foam filling the voids of the open-cell foam. In order to enable to use less foamable composition (7) to fill the voids of the open-cell foam, the core layer (1) is laid onto the lower mold surface (5) and the foamable composition (7) is sprayed onto the core layer (1) lying onto the lower mold surface so that the foamable composition (7) can penetrate at least partially by gravity into the open-cell foam core layer (1). Moreover, the foamable composition (7) has a dynamic viscosity, measured at a shear rate of 1/s, of lower than 1000 mPa·s when arriving onto the core layer (1).

    Abstract translation: 泡沫制品从芯层（1）开始制造，该芯层包括柔软的开孔泡沫体，其具有形成开孔泡沫体积的至少90％的空隙。 将核心层（1）可选地与上部（3）和/或下部覆盖层（2）一起施加在模具（6,8）中，在下部（5）和上部模具表面（9）之间， 其中。 关闭模具（6,8），并使可固化的可发泡组合物（7）在模具中发泡以产生填充开孔泡沫体的空隙的另外的泡沫。 为了能够使用较少的可发泡组合物（7）以填充开孔泡沫的空隙，将芯层（1）铺设在下模具表面（5）上，将可发泡组合物（7）喷涂到 芯层（1）位于下模具表面上，使得可发泡组合物（7）可以至少部分地通过重力穿透到开孔泡沫芯层（1）中。 此外，当到达芯层（1）时，可发泡组合物（7）具有在1 / s的剪切速率下测得的低于1000mPa·s的动态粘度。

    Abstract: A foamed elastomer is presented, manufactured from a foam precursor composition comprising at least one elastomer resin, preferably an ethylene-propylene-diene resin, at least one thermoset resin, preferably a melamine-formaldehyde resin, a curing agent, and a blowing agent. The elastomer composition optionally further includes cure activators, polymerization accelerators, and a filler material. An important feature of the present invention is that the foamed elastomer has a low density and a high modulus, making it particularly suitable as a shock absorber for a bicycle suspension apparatus.

    Abstract: Coated porous materials that exhibit air permeability and repellency to liquids as well as coated, nonporous breathable materials are described as suitable for making ileostomy vent filters, transdermal drug substrates, agricultural and medical apparel, as well as paint and chemical protective garments. The coating composition is applied as a curable composition containing cross-linkable melamine, polyol and fluorocarbon alcohol precursors. Hydrophilic coatings may be prepared by incorporating a polyvalent salt with the curable composition.
