However, a comparison of CLTE
of the amorphous polymers with that of minerals shows about an order of magnitude lower CLTE
was determined using the guidelines for determination of the CLTE
of plastic lumber (ASTM D6341-98, 1999).
along the crystallographic a-axis is the highest, whereas CLTE
along the crystallographic c-axis is the lowest (1), (26), (27).
can also be defined as the one that maximizes the CLTE
for a given value of p:
These data are similar to results on RO6002 and CLTE
In addition to CLTE
, plug material strength (as measured by flexural toughness according to ASTM D790) can play an important role in design.
Compared to traditional E-glass, HiPer-tex fiber reportedly delivers superior performance, with up to 30% higher strength, up to 17% higher stiffness, 30% lower CLTE
(coefficient of linear thermal expansion), ten times longer life time in fatigue, and significantly higher corrosion and temperature resistance.
2] filler is capable of decreasing the CLTE
while the HDT of the iPP matrix is relatively unchanged.
According to the company, benefits for typical applications include fine-tuning CLTE
(coefficient of linear thermal expansion) in grades for automobile bumpers and instrument panels, cycle time reduction and warpage elimination in the production of pallets and crates, and increased processability and optic enhancement in packaging.
announced the availability of CLTE
-AT, the latest addition to the CLTE
The superb surface aesthetics, very low CLTE
thermal expansion values and excellent paint adherence were among the other key determinants in choosing this material.
This work has resulted in the identification of improved filler technology and two RIM fascia polymers that provide high surface quality, low moisture distortion and CLTE
, and lower heat sag than commercial PU/urea RIM systems.
