    摘要: A curable composition and method for producing high strength in-the-ear products using solid freeform fabrication techniques. More specifically, the present invention provides a curable composition and method for the production of hearing aid components using stereolithography. The curable composition may include at least one acrylate oligomer, at least one reactive diluent and a cure system. The composition when cured desirably produces one or more of the following properties: Shore D hardness of at least about 85; tensile modulus of at least about 300,000 psi; and flexural modulus of at least about 300,000 psi. Suitable hearing aid components include, for example, hearing aid housings and tips.

    摘要: A curable composition and method for producing a soft yet durable elastomeric in-the-ear product having a Shore A hardness of about 55 or less upon cure. The curable composition incorporated in a hearing aid apparatus provides a soft, flexible tip member which was mated to a rigid hearing aid shell. The tip member provides better comfort, durability and acoustic performance for a variety of ear canal shapes and movements. The curable composition which provides these properties includes a urethane acrylate oligomer and a reactive plasticizer or reactive diluent to provide a Shore hardness of about 55 or less upon cure. The curable composition may be used for other ear-worn products where these properties are desired like for ear plugs, ear phones and ear connectors.
