Packing, Storage, Transportation
1 PTFE is packed in double layer PVC bags inside and in hard circular barrels outside. On the barrel, there should be attached label and quality certificate, on which there are brand, trademark, executive criterion, type, grade, lot No., net content, pack date, checker and packager.
2 PTFE should be stored in clean dry warehouse to prevent fromdust, 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-bumpines and compression is apt to make the resin bind together.
