No. 62/248,196, filed Oct. 29, 2015. The entire content of the applications referenced above are hereby incorporated by reference herein.As a method of birth control, condoms have many advantages of low-cost, easy to use, and providing protection against numerous sexually transmitted infections (STIs). However, the drawbacks to more universal and consistent use of condoms are their tendencies to decrease pleasure and/or induce the loss of erection. The reason for these obstacles is that condoms are made from hydrophobic materials, such as latex, polyurethane, and polyisoprene. These hydrophobic materials are excluded from the human physiological environment, such as the surface of the skin. Thus, currently used condoms always cause the foreign body sensation to decrease pleasure and/or induce the loss of erection.In addition, condoms are currently most often made from natural latex, which is derived from the sap of some plants. However, the use of latex condoms may cause allergic symptoms in people with an allergy to latex. In some ...

The material is formed by applying a stress to a thermoplastic composition that contains first and second inclusion additives dispersed within a continuous phase that includes a matrix polymer. Through the use of particular types of inclusion additives and careful control over the manner in which such additives are dispersed within the polymer matrix, the present inventors have discovered that a unique, multimodal porous structure can be achieved.

One-step method of producing an elastic, breathable film structure

A one-step method of imparting breathability and elasticity to a film includes coextruding elastic fibers within a matrix of a filled, semi-rigid film structure. Once the elastic fibers are within the film structure, the film can be stretched to impart breathability, while the elastic fibers provide elasticity. Furthermore, the elastic fibers can include an absorbent material. The resulting breathable, elastic film is particularly useful in diapers and other personal care products.

Abrasion-resistant, aesthetic surface layer laminate

A thick aesthetic laminate surface layer is achieved by using pre-cured particulates of the impregnating resin along with an initial binder material and preferably also abrasion resistant mineral particles. The protective overcoating may be applied in a thick layer to give gouge resistance and a deep look. Because the impregnating resin and the pre-cured particulates have the same index of refraction, the transparency of the coating and the resultant clarity of the underlying decor sheet are excellent.

Aluminum alloy composite and method for joining thereof

The object of the present invention is to strongly join an aluminum alloy part with an FRP prepreg. An object obtained by subjecting an aluminum alloy to a suitable liquid treatment so as to form a surface having large, micron-order irregularities and also fine irregularities with a period of several tens of nanometers, eliminating the presence of sodium ions from the surface and additionally forming a surface film of aluminum oxide, which is thicker than a natural oxide layer, has been found to have a powerful adhesive strength with epoxy-based adhesives. By simultaneously curing an FRP prepreg which uses the same epoxy-based adhesive in the matrix, an integral composite or structure in which FRP and aluminum alloy have been united at a joining strength of unprecedented magnitude is produced.
