  • Patent number: 4756949
    Abstract: In accordance with the invention, compositions of matter are provided for forming visco-elastic materials to simulate the physical feel of natural human soft tissue, such as fat or breast tissue. The compositions preferred are formed from a major portion of plasticizer and a minor portion of a resin. In a preferred embodiment, about 1100 parts by weight of a dialkyl phthalate plasticizer are thoroughly mixed with about 100 parts by weight of a polyvinyl chloride resin at an elevated temperature to form the visco-elastic material of the present invention. Included in the preferred composition are minor amounts of an epoxidized soybean oil stabilizer and a metallic salt stabilizer. A method is provided for producing visco-elastic materials and for producing pad structures comprising, preferably, an outer unattached covering of an elastic closed cell neoprene material and a core of said visco-elastic material.
