TESTING MIRATEC'S PERFORMANCE
Since 1998, unprimed MiraTEC Trim has been installed on a picket
fence outside the plant where MiraTEC is manufactured in Towanda,
Pennsylvania, which is in the northeastern part of the state. The
Trim has been exposed to 10 years of hot, humid summers, and cold,
snowy winters. Even without primer or paint, the Trim has held up
remarkably well. Several physical property tests were conducted on
the material in April of 2008.
CMI holds material for future testing, called 'retains,' from
production runs. Retains from the same production time period as the
fence material were tested to measure the change in properties after
10 years of exposure. The results verify the exceptionally
consistent performance of MiraTEC. The drop off in physical
properties was very minimal. The average change in the results for
each test is as follows:
24 Hour Water Absorption Test
This test indicates the amount of water MiraTEC Trim absorbs when
submerged in water for 24 hours. The measurement indicates an
increase in weight by percentage.
Thickness Swell Test
The thickness swell test is conducted by soaking MiraTEC Trim in
water for 24 hours and measuring the size of the Trim before and
after, to determine how much the Trim has swelled.
MOR test
The MOR or modulus of rupture, verifies strength of MiraTEC Trim by
bending it until it breaks.
Boil Swell Test
The boil swell test is similar to the Thickness Swell test, except
the MiraTEC Trim samples are submerged in boiling water for 1/2 hour,
then measured for caliper or thickness swell.
All of these tests are designed to help predict the long term
performance of wood composite materials. These tests are regularly
conducted on the production of all of the products CMI makes.
The performance of MiraTEC is among the very best in the exterior
trim category today.
