How does polyethylene perform in high-altitude environments?
Polyethylene, a widely used polymer, exhibits unique performance characteristics in high-altitude environments. At elevated altitudes, factors such as reduced atmospheric pressure, lower temperatures, and increased UV radiation can impact its properties. Studies show that polyethylene maintains good mechanical strength and flexibility under these conditions, though prolonged exposure to UV light may cause gradual degradation. Its low-temperature toughness makes it suitable for applications like aerospace and outdoor equipment. However, additives or coatings are often recommended to enhance UV resistance. Overall, polyethylene remains a reliable material for high-altitude use, provided proper design considerations are applied.
