PACKING,STORAGE AND TRANSPORTATION
1. PTFE Fine powder be packed in double layers plastic bag, then placed in cardboard drum, 25kgs per drum. One drum attached a label, which should be marked the brand, batch No., weight and certificate of quality on.
2. PTFE Fine powder should be stored in clean, cool and dry warehouse to prevent possible contamination such as dust, moisture etc.
3. Exhaust equipment is necessary when processing temperature is high. The temperature should be below 390°C.
4. The product are transported according to non-dangerous materials. High temperature, moisture and strong shock should be avoided during the transportation.
