On the barrel, there attached label and quality certificate, on which there are brand, trademark, lot No. and net content = 20kg. 2PTFE should be stored in clean fry warehouse to prevent from dust, moisture, etc, foreign matters. 3The 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.
