PA12 Low-temperature Resistance Toughness Application
Fenómeno do problema
【Problem phenomenon】Plastic parts in low-temperature environments cracked brittlely, and conventional nylon had insufficient toughness at -40℃
Análise das causas
PA12 low-temperature resistance can reach -70℃, and impact strength remains excellent at -40℃; this characteristic is scarce when selecting materials for clips and pipe fittings of cold chain, outdoor, and cold-region equipment
Solução
Prioritize evaluating PA12 for low-temperature working parts and perform low-temperature impact verification; toughened grades cover more severe scenarios; structurally strengthen locations where assembly stress and low temperature superimpose; after adjustment, take consecutive samples to verify the effect, and resume mass production only after confirming stability
Conclusão principal
-70℃ low-temperature resistance is a scarce capability of PA12; do not ignore it when selecting materials for cold-region parts; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
