ABSTRACT:
A foam generating and spraying apparatus adapted to receive a quantity of polymeric resin and a foaming agent therefor, and emit the foamed product thereof, comprises a resin conduit having an inlet and an outlet end; a foaming chamber having an inlet and an outlet end being disposed coaxially with respect to the resin conduit; a resin inlet upstream of the resin conduit for admitting a quantity of pressurized polymeric resin thereto; a foaming agent inlet upstream of the foaming chamber for admitting a quantity of pressurized foaming agent thereto; a mixing chamber downstream of both of the resin conduit and foaming chamber; and, a spray member disposed at the outlet end of the resin conduit for establishing a hollow cone spray of resin, and angularly directing that spray against the walls of the mixing chamber. Methods for generating a foamed polymeric resin and the products produced thereby are also disclosed herein.
