ABSTRACT:
This invention relates to a moldable foamed polymer composition that can be molded at relatively low ambient temperatures and pressures. The moldable composition comprises a wax and particles of a foamed polymer, the wax being present in an amount capable of bonding the particles together in a coherent body. A method for forming articles from said composition along with processes for using said molded articles are also disclosed.
