What Is Expanded PTFE Gasket Sheet?
Kaxite
Kaxite 8600 Expanded PTFE Gasket Sheet is a soft and also compressible
gasket material manufactured from completely absolutely pure
multi-directionally expanded PTFE. Expanded PTFE Gasket Sheet is
actually resistant to almost all chemical compounds as well as has
excellent creep and cold flow resistance. It can withstand a wide range
of pressure and temperature conditions, and also it is suitable for
tight sealing of bolted joints in most industries like chemical,
petrochemical, food, power generation, pulp and paper and other general
industrial application.
Ningbo
Kaxite as the one China leading Manufacturer and supplier of expanded
PTFE gasket sheet with competitive price to the world market, our EPTFE
gasket sheet is also suitable for sealing flanges with unusual
surfaces. It will not present the cold flow issues in comparison with
virgin PTFE, or the hardness problems compared with some filled PTFE
products. It has superb sealing overall performance, and can be cut
easily and split up cleanly from flanges after using. This product is
FDA compliant.
In
order to offer a fast and efficient service to our customers, we stock a
large quantity of Expanded PTFE Gasket Sheet in different thickness and
dimensions. The thickness of expanded PTFE Gasket sheet we produce and
stock can be from 0.5 mm to 8 mm, and the width and length usually
1520mm. Customers special dimension sizes needed is acceptable.
Application of Expanded PTFE Gasket Sheet
Expanded
PTFE gasket sheet material conforms to FDA rules for food contact.
Expanded PTFE gasket sheet is an all purpose gasket sheet that will
replace all other kinds of PTFE sheet. It will eventually seal all
aggressive chemicals over the whole 0 to 14 pH range, except molten
alkali metals and elemental fluorine. Constructed from 100% virgin PTFE,
and expanded ptfe gasket sheet is perfect for industries such as Iron
and Steel manufacturing, Food and Beverage, Power Generation, General
Chemical, Petrochemical, Pharmaceutical, Pulp and Paper and Marine.
What Advantages Make the Expanded PTFE Gasket Sheet Unique?
As
we all known that expanded PTFE gasket sheet is used widely for general
industrial applications and have very good sealing effect when it is
used as a seal gasket. And below content is about the reason why it is
so popular and unique in sealing field.
1 - Exceptional resistance to creep and cold flow
Because
Expanded PTFE Gasket Sheet offers excellent tensile strength, so it
keeps superb dimension stableness when it is in use both in thickness
and width, compared to any other PTFE material gaskets.
Due
to its thickness remains much more dimensionally steady than other
types of PTFE material gaskets, Expanded PTFE Gasket sheet can conserve a
higher percentage of bolt load in operation, delivering a bit more
efficient seal particularly energy cycling and higher temperatures
circumstances.
The
width of Expanded PTFE Gasket Sheet also stays more dimensionally
stable, staying away from gasket intrude in to the pipe bore which could
negatively influence sealing result.
2 - Particularly reliable sealing performance
compression
tests clearly show expanded ptfe gasket sheet is great at bearing the
serious circumstances of industrial flange sealing. It shows a excellent
overall performance of seal durability both at setting up and
functioning at raised temps.
Expanded
PTFE Gasket Sheet is actually resistant to most chemical compounds, it
can still have excellent performance of sealing duration in robust
alkali, strong acid and solvent-based procedure techniques. It
withstands just about all mass media (pH 0-14) excluding molten,
dissolved alkali metals and elemental fluorine.
