Long-term dimensional stability of PCTG products
Problembeschreibung
Product dimensions slowly change during 1-2 years of use.
Ursachenanalyse
Slow processes of stress relaxation and post-crystallization, affected by ambient temperature changes.
Lösung
Full annealing for stabilization; consider long-term dimensional stability allowance in design.
Wichtigste Erkenntnis
PCTG long-term dimensional stability tests the microscopic stability of the material.
