PVC rain boots in low temperature environment will become very brittle and hard

Yes, pvc rain boots may indeed become brittle at low temperatures. PVC materials lose their flexibility at low temperatures and become more brittle, because as the temperature drops, the movement of PVC molecules slows down, resulting in reduced flexibility.

Therefore, in cold weather, PVC rain boots may become less flexible, and even prone to cracks or breaks. This is also why special care needs to be taken when using PVC products in low temperature environments to avoid damage due to the brittleness of the material.

If you are using PVC rain boots in a cold environment, it is recommended to choose a material with better cold resistance or take some warmth measures to reduce the risk of the rain boots becoming brittle due to low temperatures. At the same time, check the condition of the rain boots regularly to ensure their integrity and functionality.
