Abstract: A method for producing a custom insole for a foot of a user, the method including the steps of providing a preformed insole precursor, the precursor being constructed of a solid material which is storable in an undeformed state and which is compressible to a deformed configuration under pressure substantially at room temperature and which retains the deformed configuration after removal of the pressure, and pressing the foot on the insole precursor, thereby compressing the insole precursor and forming an insole with a configuration in accordance with the configuration of the foot.

Abstract: Polymer matrix composite materials containing a thermoplastic composite core bonded integrally with a fabric layer are provided. The fabric layer has a greater elasticity than the core, so that the fabric layer can conform smoothly to the core during thermoforming. This improvement has been demonstrated to improve aesthetic appearance and nearly eliminate wrinkling and distortion of the fabric layer when compared to conventional composite materials.

Abstract: Orthopedic splint materials made with thermoplastic polyester, particularly poly (epsilon-caprolactone) with a molecular weight of over 5,000 and melting between 50.degree. C. and 100.degree. C. have improved properties when subjected to gamma radiation in the range from 0.5 to 30 megarads.

Abstract: A method for making a thermoplastic-rubber wader having a rubber footwear bottom and a thermoplastic upper, the method including the steps of treating an upper circumferential portion of the bottom, applying thermoplastic adhesive to the treated portion, applying a thermoplastic strip to the adhesive coating, applying a thermoplastic band to the upper to provide an interfacing annular seating surface with the thermoplastic strip, heat sealing the strip and band to provide a fluid tight unitary bond between the bottom and the upper and the wader formed by the above method.

Abstract: An antistatic polymer blend composition and articles made therefrom are disclosed. The composition comprises, based on parts by weight: (a) polyvinyl chloride: 100 parts; (b) carboxylated nitrile terpolymer: 30-40 parts; (c) nonionic antistatic agent: 5-8 parts; (d) metallic stabilizers: 2-5 parts; (e) epoxidized oil: 5-10 parts; (f) primary plasticizer: 50-90 parts; and (g) lubricant: 1-2 parts. A method of protection against the effects or build up of antistatic electricity employing articles made from the composition of the present invention is also disclosed.

Abstract: This invention covers a shoe sole composition compounded from polyvinyl chloride and organic cellulosic flock, and the shoe sole product produced therefrom.
