What is “Nylon Zipper Tensile Strength“ Question 1: What is the tensile strength requirement for nylon zippers as per the Chinese Light Industry Standard? According to the Chinese Light Industry Standard for nylon zippers (document number: QB/T 2171~2173-2001), the tensile strength, or the “Lateral Strength,“ is a crucial indicator of a zipper's structural integrity under stress. The standard specifies the minimum tensile strength that different sizes of nylon zippers must achieve. For example, a size 3 zipper must withstand at least 340 N, while a size 5 zipper must handle 500 N without breaking or coming apart. Question 2: How did our nylon zippers perform in the tensile strength test? Our company conducted rigorous tensile strength tests on our nylon zippers, and the results were outstanding: The average tensile strength of our size 3 zippers reached N. The average tensile strength of our size 5 zippers was N. Question 3: How do the
