INHERENT PROPERTIES OF POLYETHYLENE LINERS
The properties listed in the table below are primarily inherent
on the resin type used to produce the liner or are directly proportional to
the thickness of the
liner and less dependent on the manufacturing method. Therefore, these properties
will not change from roll to roll or even lot to lot. Hence, they should not
be included as part of
routine quality control testing. The exception to this is Oxidative Induction
Time. This test is a measurement of the amount of anti-oxidant added to the
resin to produce the finished sheet.
This test can function both as a performance test and a quality control test.
As a quality control test it is desirable to run the test at high temperatures
to keep the test duration short.
This test is routinely run at the time of manufacture. As a performance test
it is desirable to run the test at lower temperatures. Testing at lower temperatures
cannot be done for quality
The information given below is based on nominal values. Individual test results may vary from these values depending upon the reproducibility of the test.
