were researched (refer to Figure 5,) it was discovered that the fired PTFE body containing 50 wt%
dispersion (Figure 5- 6 ) had equivalent tensile
strength and tensile elongation in comparison with
fired PTFE body consisting in only dispersion (Figure 5- 2 ), 30% lower tensile strength and a 20%
higher tensile elongation in comparison with fired
virgin PTFE body (Figure 5- 1 ), 4 times higher tensile strength and 8 times higher tensile elongation
in comparison with fired recycled PTFE body (Figure 5- 3 ).
Even though the target was to be equal to the
mechanical properties of the fired virgin PTFE
body, the results shown in Figure 5- 6 and 7 were
well beyond our estimates. Also, more content of
the dispersion did not necessarily lead to dramatic
increase in tensile strength and tensile elongation.
As there was no major change between 50 wt% and
80 wt% contents of the dispersion, the 50 wt% content should be sufficient.
In the future, if it is possible to maintain equivalent tensile strength and tensile elongation for
recycled PTFE with lower dispersion ratio, the cost
can be lowered further, and the realization can be
promoted very efficiently.
Expectation for Recycled PTFE Mixed with
Dispersion
Several key points and aspects in3 were reviewed.
Many of the dispersion research facts finally provides the "conclusion." Through the experimental
results of3, a new possibility was discovered for
recycled PTFE mixed with 50 wt% dispersion (Figure 5- 6 3). The following two points holds special
promise.
1 New applications as new material can be expected by using higher tensile elongation than
that of fired virgin PTFE body (Figure 5- 1 ).
2 As the fired body with the same strength
with that of fired PTFE body consisting of 100
wt% dispersion (Figure 5- 2 ) can be obtained
by adding 50 wt% dispersion (Figure 5- 6 ), an
early practical realization is expected in the
existing field where dispersion is used.

Figure 5. What draws attention is R-PTFE + D-PTFE 50 wt%, surrounded in
red frame in the upper table. In the table in the middle, its tensile strength
and tensile elongation are high in comparison with those of R-PTFE.
