Abstract
A method for making a resilient material includes providing a particulate polymer, discrete pieces of foam, a foaming agent and a plasticizer. The polymer, foam pieces and plasticizer are mixed and disposed in a mold. The mold is heated to cause melting of the polymer without melting of the foam. After coating of the melted polymer, a heterogeneous resilient cushion is formed with gelated polymer surrounding the discrete foam pieces.
Claims9
A composition for making a resilient material, said composition comprising a homogeneous mixture of a polymer in particulate form and discrete pieces of foam material, said polymer having a lower melting temperature than said particulate foam for enabling melted polymer to galate around the foam pieces to form a heterogeneous resilient, material when the mixture is heated.
A composition fir making a resilient material, said composition comprising a homogeneous mixture if a polymer in particulate form and a temperature than an expansive temperature of the foaming agent and a lower melting temperature than a temperature causing rupture of expanded foaming agent in order to enable melted polymer to gelate around the expanded foaming agent to form a heterogeneous resilient material when the mixture is heated.
