Features: Pure, multidirectionally expanded PTFE,
asbestos free, chemically resistant to fluids from 0 to 14 in the pH
range. Limitations for uses with flourine and alkali metals at high
temperature and pressure. Planiflon E does not age, does not harden and
is the sealant that raises the qualities of PTFE and reduces their
limitations.

Recommended Uses: Thanks to its unique structure, Allstate
1199 is able to face many application problems in the chemical,
pharmaceutical and food industry where PTFE should be the best solution
if it is able to offer improved mechanical characteristics in comparison
to the full density, skived PTFE. Practically, the cold flow of this
surface up to 100 N/nm2. Planiflon is also particularly indicated for
low clamping load applications in the presence of fragile flanges
(graphite, glass, etc.) thanks to its very positive deformation curve,
and grants long lasting and self operative life. FDA suitable (231 CFR
177.1550).
