摘要 |
A process and apparatus for producing a polymeric foam, wherein foam components are brought together under pressure and are passed through a permeable discharge head where the pressure is reduced. The permeable discharge head comprises a diffuser element having a structure such as to require division, divergence and convergence of flow paths in three dimensions within its axial thickness, considered in the direction of flow therethrough. The diffuser element comprises plural individual woven wire meshes sintered together to form a composite element. The invention also provides the diffuser element. |
