Usage
The resin is suitable for moulding pressing process and making rod, sheet, pipe, film and
gasket. It's also can produce PTFE presintered material.

Packing, Storage and transportation
1,PTFE is packed in double layer PVC bags inside and in
hard circularbarrels outside. On the barrel, there attached label and quality certificate, on whick there are brand, trademark, lot No. and net content = 20kg.
2,PTFE should be stored in clean fry warehouse to prevent from dust, moisture, etc, foreign matters.
3,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.
