Dimensional Stability Advantage of PA12 Low Moisture Absorption
문제 현상
【Problem phenomenon】PA6/PA66 products expanded beyond tolerance after moisture absorption, and a dimensionally stable nylon substitute was sought
원인 분석
The equilibrium moisture absorption rate of PA12 is only 0.25-0.9%, while PA6/PA66 reaches 2.5-3.5%; low moisture absorption keeps PA12 wet-state dimensions and performance stable, making it the first choice for precision nylon parts
해결 방법
Switch precision nylon parts in humid and hot environments to PA12; recalculate dimensional tolerances according to the difference in moisture absorption rate; glass fiber reinforced PA12 further reduces shrinkage and moisture absorption influence; after adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
핵심 요약
Moisture absorption 0.25-0.9% versus 2.5-3.5%, PA12 is the dimensionally stable nylon answer; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
