Dyneon TF-9205

TF-9205为热降解工艺在德国生产的聚四氟乙烯微粉，不同TF-9207的乳液聚合工艺。TF-9205平均粒径为8微米，特别容易分散。所以在涂料和橡胶中特别适合。质量肯定是同类别中最好的。

Technical Information

Processing recommendations

PTFE micropowders can be used as additives in many different applications and at

concentrations typically from 5 to 20%. Homogeneous incorporation helps ensure optimum

performance. Because of its small particle size coupled with good free-flowing properties, Dyneon

TF 9205 PTFE exhibits very good metering behavior and can be easily incorporated into other

materials – even in dry blends.

Supply Form

Dyneon TF 9205 PTFE is supplied in 25-kg cartons with polyethylene liner or large cartons

containing individual bags of 25-kg each.

Storage

Dyneon TF 9205 PTFE can be stored for a relatively long period of time. It should be kept in a clean

and dry place in its original unopened container at temperatures below 30°C (86°F).

*Typical values (not for specific purposes)

**The measurements are carried out at 372°C (701°F) (test weight 2.16-kg, die diameter

1.0mm). The melt viscosity of micropowders can be calculated from the melt flow rate

(MFR) by Hagen-Poiseuille’s law to obtain an indication of molecular weight.
