The fish are getting stronger in the super cold?
Nylon is weaker?
Nylon virgin resins are difficult to maintain good performance under super-low temperature working conditions, and brittle fracture at super-low temperatures has become the norm ……
The above information is obtained from a search on Baidu. Nylon 6 is resistant to low temperatures between -20 and -40°C, but when it reaches -50°C, the nylon parts will not meet the requirements of use and will produce brittle fractures.
Low temperatures, a pain point for nylon itself
At present, the most common way is to add modified additives.
A large amount of data shows that POE-g-MAH, an ethylene-octene copolymer grafted with maleic anhydride, has good performance in the low temperature toughening of nylon.

Coace W1B
W1B is a maleic anhydride functionalised ethylene-based elastomer with an extremely low glass transition temperature, making it particularly suitable for ultra-low temperature toughening of nylon at -50°C.
