    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.

    摘要: A curable composition having enhanced cure speed which includes a curable component, a cure system and an additive for enhancing cure speed. The additive includes an alkali metal halide salt and the reaction product of: (a) a polyfunctional isocyanate and a member selected from the group consisting of an hydroxy and an amine; or (b) a phosgene or phosgene derivative, and a compound having 3 to 7 polyethylene glycol ether units terminated at one end with an ether group and at the other end with a reactive functional group selected from the group consisting of an amine, an amide, a thiol and an alcohol; or (c) a monohydroxy compound, a diisocyanate and a polyamine. Alternatively, in place of or in combination with the cure speed enhancing additive, an aromatic substituted (meth)acryl functionalized component may be incorporated into the curable component to achieve enhanced cure speed.

    摘要: A curable composition and method for producing a tear resistant, yet soft and deformable in-the-ear product yielding the user greater comfort and durability. The curable composition incorporated into a hearing aid apparatus provides a deformable, yet tear resistant housing, which may be mated to a soft tip component. The hearing aid housing provides better comfort, durability and acoustic performance for a variety of ear canal shapes. The curable composition that provides these properties includes at least one urethane acrylate oligomer, at least one reactive diluent and a cure system. The composition when cured desirably produces a tear strength of at least about 75 pli and a hardness of about Shore A 60 to about 75.
