PA hydrolysis and performance decline in hot water environment

문제 현상

원인 분석

Cellulose acetate butyrate hydrolysis reaction accelerates in hot water, molecular chain breakage Large mechanical property decline after hot water immersion PA66 hydrolyzes faster than PA6 Long-term hot water use requires hydrolysis-resistant modification The higher the hot water temperature, the faster the decay rate

해결 방법

Select hydrolysis-resistant PA grades or modified grades Hot water applications require long-term immersion verification PA12 has good hot water resistance, preferred Lower the use water temperature to slow decay Add anti-hydrolysis agents

핵심 요약

PA hot water resistance requires selecting suitable grades and verification
