PTFE FINE POWDER DF-203
PTFE Fine Powder DF-203
PTFE (POLYTETRAFLUOROETHYLENE) is one of the most important plastic resins which has been applied in many fields,for its special properties, such as : chemical resistance and stability ;High continuous service temperature (260ºC); Very lubricious - lowest coefficient of friction of any polymer; Chemical and solvent resistance; Electrical resistance; High melting point (342ºC/648ºF).

16 | Packing,Storage Transporation | 1.PTFE is packed in double layer PVC bags indide 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.and net content,pack date, checker,,packager. 2.PTFE should be stored in clean dry warhouse to prevent from dust,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-bumpiness and compression is apt to make the resin bind together. | ||||
