――Climate resistance properties:
It has excellent weather-resistant performance and can maintain its high strength and high modeling under long time light. After a large number of tests found that its resistance to ultraviolet irradiation is much better than other chemical fibers, continuous exposure to light up to 1500 hours, its strength retention rate is still more than 90%, while other chemical fibers this indicator is generally 40%.AroundAnd even lower.

Tension fatigue properties
The rope made was subjected to a thousand cycles of load level testing, and its strength was basically completely maintained, with excellent tensile fatigue resistance.
