Hello,
Does anyone know if HDPE/LDPE has a finite lifetime? Reason we had a small HDPE bottle of methanol which suffered brittle fracture during use (kinda snapped apart in the users hands). The bottle had been used for at least 6 years. We've since replaced the bottles with Nalgene LDPE ones.
From what I can gather, both HDPE and LDPE are compatible with methanol, and can last indefinitely in the right situations. UV and oxidation are the biggest threats to the integrity of the plastic.
The LDPE is softer, so perhaps if it does fail, it won't shatter as did the HDPE bottle?
Any comments are appreciated
