Dimensional stability testing, color

Dimensional testing includes stability tests for shrinkage and other distortions, such as recovery rates for elasticity. Dependent on ink penetration, stretching can reveal the ground color through the print. 

Another PPS success story in the electrical/electronics industry concerns use of PPS in televisions.26 Here requirements included high temperature resistance, precision moldability, good arc tracking resistance, and good dimensional stability. Again, numerous materials were tested, but a fiberglass-reinforced PPS compound proved to be the material of choice for a series of pin cushion corrector coils used in color television sets.
