Beschreibung
Zusammenfassung:	A screw removal aid for resin processing machines, characterized by comprising a resin composition containing (A) a lubricant having a surface tension of 32 mN/m or less and a melting point or a softening temperature of 70 DEG C or higher and (B) a thermoplastic resin having a surface tension larger by 5 mN/m or more than that of the component (A), also characterized by having a surface tension of32 mN/m or less after being warmed at 80 DEG C for 16 hours. 本发明提供一种树脂加工机用的螺杆拔出辅助剂，其特征在于，该辅助剂含有树脂组合物，该树脂组合物含有：表面张力为32mN/m以下、熔点或软化温度为70℃以上的润滑剂(A)；以及具有比(A)成分大5mN/m以上的表面张力的热塑性树脂(B)，该辅助剂在80℃加热16小时后的表面张力为32mN/m以下。
