Attention:

1. PFA is stable and non-volatile at normal ambient temperature, but it will decompose and release certain toxic gases when it is subjected to high temperature during forming process. Therefore, in the process of moulding, extrusion and injection moulding, it is need to ensure good ventilation.

2. In the process of processing, the decomposition gas of PFA may cause corrosion to the equipment, so it is necessary to avoid the long residence time of PFA in the equipment at high temperature.


Packing & Storage & Transportation:

1. The product is packaged in polyethylene plastic bags and then packaged in cardboard boxes with a net weight of 25 kg per box.

2. It should stock in clean, cool and dry warehouse, prevent from agglomeration and contamination.

3. This product is non-toxic, non-explosive, non-corrosive, according to non-dangerous goods transport.
