PE (polyethylene) layflat hoses generally have good resistance to sunlight (UV) and cold temperatures. Polyethylene is known for its excellent UV resistance, which means that PE layflat hoses can withstand prolonged exposure to sunlight without significant degradation or loss of performance. They are also designed to remain flexible and functional in cold temperatures, although the specific temperature range may vary depending on the manufacturer and grade of the PE used.

However, it's important to note that prolonged exposure to extreme temperatures, both high and low, can gradually affect the overall lifespan and performance of any hose, including PE layflat hoses. To ensure the longevity and optimal performance of your layflat hose, it is recommended to follow the manufacturer's guidelines and consider proper storage, protection, and regular inspection to identify any signs of wear or damage.
