Description
QuadraLonTM is a homogenous PTFE sheet
which uses product geometry rather than fillers or binders to
address concerns associated with traditional PTFE gasket
material. Leader Global Technologies’s “dog bone” crosssection
(patent applied for) allows the sealing material to be
restructed into thick, low-density walls surrounded by thin,
high-density quadrants.
Advantages
The proprietary “dog bone” cross-section
allows QuadraLonTM to be a multiple density, multiple
thickness material which results in a gasket that is both thick
and thin. The thick, low-density PTFE walls accommodate
flange distortion. Consistent with traditional gasket theory,
the thin, high-density quadrants provide the thinnest material
possible for improved load transfer and torque retention. The
higher density quadrants also act as a dam or barrier to the
thicker walls which helps prevent material creep or the tendency
for the gasket to become thinner without additional
applied pressure. The unique pattern also has a higher
tensile strength for better handling.
Applications
QuadraLonTM is designed for oxidizing
applications, harsh chemical environments, and areas where
contamination is a problem. Because QuadraLonTM addresses
bolt creep with material geometry rather than binders and
fillers used by other “low creep” PTFE products, it is completely
chemically inert but still has better creep resistance. With
QuadraLonTM, one PTFE sheet will meet all your needs.
