How much strength may polypropylene line lose in 3 months when exposed to tropical sunlight without ultraviolet inhibitors?

Polypropylene line is known to degrade when exposed to ultraviolet (UV) radiation from sunlight, particularly in tropical environments where sunlight exposure is more intense. Without UV inhibitors, polypropylene can experience significant loss of strength over time, as the UV rays break down the molecular structure of the line.

Research and practical observations indicate that after approximately three months of continuous exposure to tropical sunlight, polypropylene line can lose about 40 percent of its strength. This degradation is critical for users to understand, as it can affect the line's performance in various maritime applications. It underscores the importance of using lines that have UV protection if they are to be used outdoors in harsh environments.

In contrast, the other percentages indicate lesser strength losses, which do not accurately reflect the significant degradation and loss of integrity that occurs in unprotected polypropylene when exposed to prolonged sunlight.
