usage

The resin are mainly used as packing products resource and

packing pelletized resuorce,which can be processed to film, the

products of thin wall, seal,gasket,club,panel,tube,axletree,seal

ring,and loop etc.

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.
