Material Identification Of Speed ​​Wire Skipping Rope

  There are many types of rope skipping, one of which is speed rope skipping, also known as high-speed rope skipping or wire rope skipping. Speed ​​rope skipping, as the name suggests, means jumping very fast. Many intermediate and advanced players who like to challenge speed will choose wire speed rope skipping.

Speed ​​​​wire skipping rope

  The wire skipping rope is very thin, usually with a diameter of 2.5 mm or 3.0 mm, and 2.5 mm is the most common on the market. Because of the small cross-section, the thin skipping rope can effectively reduce wind resistance and increase the rotation speed. But a skipping rope that is too thin is relatively light in weight and tends to float when jumping. In order to increase the weight, steel wire is used as the inner core and covered with a plastic outer skin. Therefore, most racing skipping ropes are composed of steel wire and a plastic outer skin. The plastic outer skin is the part that directly contacts the ground and generates friction during exercise, and the life of the wire skipping rope mainly depends on the wear resistance of the outer plastic outer skin.

Which plastic cover material is better?

  The commonly used materials for plastic outer skins are mainly PVC, PU and nylon. According to the communication between manufacturers in the industry, everyone believes that PU material will have better wear resistance when used in skipping ropes.
I asked the manufacturer: How much difference is there in the wear resistance of these three materials in actual applications? Are there any standards and test comparison data reports for reference? The manufacturer replied: In the skipping rope industry, everyone comes from experience. There are no standards and no test reports. Just believe in my quality! Of course, such an answer will definitely not satisfy people.

How to distinguish between PVC and PU skipping rope covers?

  There is almost no difference between the two materials in appearance and feel, but there is a quick way to distinguish them:burn.Both materials will emit smoke when burning, and the smoke from PVC is slightly larger, but not too obvious. PU burns faster, and liquid will drip after the plastic melts, while there is no dripping when PVC burns. After burning, PU burns more fully, the end is flat, and the steel wire is exposed; while PVC has residue attached to the steel wire after burning, and ashes fall off when peeled by hand.This is a relatively quick and convenient but not very rigorous method to identify materials. Even for the same material, the combustion phenomenon may be different due to the formula, process, etc.
