PROCESS FOR MANUFACTURING A DENSIFIED POLYMER POWDER, AND PROCESS OF MELT PROCESSING A DENSIFIED POLYMER POWDER |
摘要 |
Process for manufacturing a densified polymer powder comprising compressing a polymer feed that has a bulk density of less than or equal to 240 kg/m in a roll compactor comprising at least two compaction rolls to obtain a densified polymer material, wherein a gap between the two rolls is 0.5 to 10 mm, wherein the compaction rolls operate at a speed of 3 to 30 rpm, wherein an applied pressure of the roll compactor is 0.5 to 5 MPa, and milling the densified polymer material to obtain a densified polymer powder, wherein a bulk density of the densified polymer powder is greater than or equal to 250 kg/m3. |
