8 Main Usage The prensintered resin is suitable for  extruding  rod ,tube , 
9 Packing,Storage,Transportation 1,PTFE is packed in double layer PVC bags inside and in hard circular barrels outside . On the  barrel , there attached lable and quality certificate ,brand, perfromance standard, variety , trademark, grade, batch, net weight, packing date,   packer, quality analyst.
2,PTFE should be stored in clean dry warehouse to prevent from dust , moisture ,etc impurity.
3,The products are transported  according to non-dangerous goods. Heat, moisture, freeaing and strong shock shold be avoided during transportation. Over -bumpiness and compression is apt to make the resin bind together.
