PTFE RESIN FOR UNIVERSE MOULDING
suspended
middle grain of PTFE, PTFE-SM031
Function Description：
The suspended resin is suitable for mould pressing process and making rod sheet pipe, film and washer material.
Additional
Explanation：
Packing Storage and transportation:
1. PTFE is packed in double layer pvc bags inside and in hard circular barrels outside. On the barrel there attached label and quality certificate on which there are brand trademark lot NO. and net content=25kg.
2 PTFE should be stored in clean dry warehouse 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
