EXTRUDED POLYMER FOAM PROCESS WITH STAGED FORMING |
摘要 |
Prepare an extruded polymeric foam by extruding a foamable polymer composition through a foaming die and allowing the foamable polymer composition to expand into a polymer foam as it travels through and is constrained in its thickness dimension by at least two constraining sections, the first having opposing essentially parallel forming plates and the second constraining section having forming plates spaced further apart than the first constraining section. |
