NON-FREELY FLUIDIZING MOLDING POWDER OF MODIFIED POLYTETRAFLUOROETHYLENE |
摘要 |
- Non-dusting moulding powder with a bulk density of NOTLESS 450 g/l, which is not free-running, consists of a suspension polymer (I) with tetrafluoroethylene (TFE) units and 0.01-1 wt.% perfluoro(alkyl vinyl) ether units with a 1-4 carbon (C) alkyl group. It is obtained by milling the primary particles to an average diameter d50 of 10-50 mu m and reagglomeration in water to an average agglomerate diameter d50 of 30-100 mu m. Also claimed is a method of producing the powder by milling and reagglomeration. |
