摘要: Thermoplastic foam sheet material is formed using an apparatus comprising extruder, means for feeding polymer into said introducing expanding agent the a low-shear mixing and cooling chamber, substantially non-shear forming die disposed to receive output of chamber. The may be polystyrene pentane, hexane or heptane. stretched.
