low shrinkage stretch tape, medium wall tube and special
unsintered tape. |
| 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. |
