Paste Extrusion |
| Usage |
It is suitable for plaster extrusion for making small-diameter,
thin wall pipe, lead and cable, raw material tape, porous sealing
material, etc.. |
| Packing, Storage and transportation |
PTFE is packed in double layer PVC bags inside and in
hard circularbarrels outsides. On the barrel, there attached label
and quality certificate, on whick there are brand, trademark, lot
No. and net content=20kg.
PTFE should be stored in clean fry warehouse to pervent form dust,
moisture, etc, foreign matters.
The products are transported according to non-dangerous products.
Heat, moisture, freezing and strong shock should be avoided during
transportation. Over-bumpiness and compression is apt to make the
resin bind together. |
