Abstract:

A method and apparatus for dispensing a polymer foam includes apparatus for forming a pressurized solution of intermixed polymeric material and gas. The polymeric material remains intermixed with the gas while the solution is maintained above a critical pressure. The pressurized solution is dispensed in wide band through an elongated slot. The dispensing apparatus includes an exit slot section in which the pressure of the solution drops below the critical pressure and the foam begins to form. The solution is maintained above the critical pressure until the solution enters the exit slot section so that premature foaming of the material is prevented.
