摘要:
Self-fitting device for location in ear canal and related method, including a bladder joined with a pump assembly via a valve assembly. The pump assembly transfers air to the bladder and achieves a predetermined pressure with the chamber regardless of ear canal size. The predetermined pressure may be achieved by reducing excess air pressure through the valve assembly.
摘要:
A soft, flexible, low-density, open-cell, thermoplastic, absorbent foam formed from a foam polymer formula including a balanced amount of a plasticizing agent and a surfactant in combination with a base resin. Thermoplastic elastomers can be added to the foam polymer formula to improve softness, flexibility, elasticity, and resiliency of the resulting foam. The surfactant may be either a single surfactant or a multi-surfactant system. The foam possesses a number of qualities, such as softness and strength, which render the foam particularly suitable for use in a variety of personal care products, medical products, and the like.
摘要:
A hybrid absorbent foam includes an integrated hybrid foam layer having an open surface, a closed surface, and a foam body extending between the open and closed surfaces. The integrated hybrid foam layer has an open-cell content of at least 50%, while the closed surface provides a barrier to aqueous liquids. The integrated hybrid foam layer is formed as a single layer, and has a substantially uniform polymer composition throughout its thickness. The integrated hybrid foam layer combines the functions of liquid absorbency, retention, and barrier into a single layer, and is useful in a wide variety of absorbent articles.
摘要:
A composition which exhibits a reversible non-linear reduction in opacity as the composition is stretched from a first length to a second length is disclosed. One embodiment is a film comprising an elastomeric polymer medium and regions having crystalline properties disposed in the polymer medium, where the film exhibits the reversible non-linear reduction in opacity upon being stretched.

摘要:
A low density, flexible, resilient, absorbent open-cell thermoplastic foam includes a combination of thermoplastic elastomer, ethylene ionomer, stiff polymer, and surfactant selected to provide various advantageous properties. The foam is useful in personal care absorbent articles, medical absorbent articles, absorbent wiping articles, and a variety of other applications.
