Introduction to the material of volleyball
The material of volleyball is divided into PU and PVC. Most of the volleyball liner is made of PU, which has good toughness and high strength. Some of the outer layers are stitched with PU, and some with PVC.
PU: It has the characteristics of resistance to torsion, good softness, high tensile strength, and also has the breathability that PVC does not have. The advantages of PU volleyball are realistic color, smooth surface, bright color, no deflation, durable, good rebound, safe to use, soft and comfortable to touch.
PVC: PVC is also known as polyvinyl chloride. The natural color of polyvinyl chloride (PVC) is yellowish translucent and shiny. The transparency is better than that of polyethylene and polypropylene, but worse than that of polystyrene. Depending on the dosage of additives, it can be divided into soft and hard PVC. Soft products are flexible and tough, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene. Below polypropylene, whitening occurs at the inflection point.
