Cannon, a leading supplier of insulation technology, has developed a foaming system based on a pouring process using a two-component polyurethane or silicon foam for the production of gaskets for appliance applications. In view of the improved quality and better technical properties achieved with a foamed gasket, the company says its gasketing technology can replace die-cut, strip, extruded, and molded gaskets. Foamed seals meet the most stringent requirements in terms of physical and mechanical properties; sealing and insulating; preventing dust, moisture, and water penetration; and also dampening vibrations and sounds. Since the resulting gasket is continuous with no recognizable joints or cut ends, the sealant is characterized by excellent performance, ensuring a great barrier against leakages compared to other kinds of seals. A high level of automation also means a significant labor cost reduction, which is often a high percentage of the total cost of a sealant production.
