Latest Patents

One of Wacker's latest patents is for a "Dispensing head for two-component foam with shutoff." This invention features a mixing and dispensing head designed for use in a two-component foam system. The head includes a body with a mixing chamber and a dispensing channel downstream of the mixing chamber. It has at least two supply portions connected to the body, each supplying one of the components to the mixing chamber at longitudinally offset entry locations. A rotating mixing member within the mixing chamber mixes the components to form the foam product. Additionally, a shutoff portion is provided to stop the flow of product from the dispensing channel.

Another significant patent is the "Method and apparatus for dispensing foam materials." This invention describes a method for dispensing a polymer foam that includes forming a pressurized solution of intermixed polymeric material and gas. The solution remains intermixed while maintained above a critical pressure, allowing it to be dispensed through an elongated slot. The dispensing apparatus ensures that the pressure drops below the critical level only at the exit slot section, preventing premature foaming of the material.
