PVC floor is the most commonly used and most popular floor in soft floor, introducing the characteristics of PVC floor
1. Comfort issues

The surface of the professional PVC plastic sports floor can be moderately deformed when it is hit, just like a sealed mattress with air inside. When you fall or slip, the cushioning effect provided by the closed foam backing technology can maximize Reduce sports injuries.

2. The problem of tremor

Tremor refers to the area where the floor is deformed by impact. The larger the tremor range, the more likely it is to cause fractures. There are two types of tremor: point tremor and regional tremor.

3. The problem of vibration absorption

The impulse formed by people during exercise will produce vibration on the surface of the PVC plastic sports floor. The structure of the floor must have the function of shock absorption, that is, the floor should have the ability to absorb impact energy. The athletes are exposed to the PVC plastic sports floor The anti-impact force is much smaller than the movement on hard ground, such as concrete. That is: when the athlete jumps back to the PVC floor, at least 53% of the impact is absorbed by the PVC floor, thereby protecting the athlete's ankle, meniscus, spinal cord, and brain. No harm. Its protection function also considers that a person can not affect the adjacent people when exercising on the PVC plastic sports floor. This is also the concept of shock absorption, shock deformation and extension deformation described in the German DIN standard.

4. The problem of friction coefficient

Studies have shown that 12% of basketball players are injured in the process of turning on the spot. The coefficient of friction of a sports floor indicates whether the floor is too frictional (which reduces the flexibility of rotation) or too slippery (which increases the risk of slipping). Considering the athlete's mobility and safety, the friction coefficient should be the best value between 0.4-0.7. The friction coefficient of professional PVC plastic sports floors is generally kept between this coefficient, it has sufficient and moderate friction, can ensure the stability of the movement, and at the same time can maintain the consistency and regularity of the friction performance in all directions of movement , To ensure that flexible movement and in-situ rotation are not hindered.

5. The problem of ball resilience

The ball rebound test is to drop the basketball from a height of 6.6 feet onto the sports floor to test the rebound height of the basketball. This data is expressed as a percentage, and the rebound height of the basketball on the concrete floor is used as a comparison standard to reflect the rebound height difference. The rules of indoor ball sports competition require that the ground be used for sports competitions or training. For example, the take-off action of a ball and other ball sports and the rebound of the ball require that the rebound coefficient of the ball on the ground of the playing field should be greater than or equal to 90%. Professional PVC plastic sports floor has outstanding and stable ball resilience performance, there is no elastic dead point on the floor, its rebound comparison coefficient can reach 98%.

6. The issue of sports energy return

This refers to the exercise energy returned by the PVC plastic sports floor when the athletes are exercising, in order to improve the exercise efficiency.

7.The problem of rolling load

The load-bearing load and firmness of the professional sports floor, and the service life must meet the requirements of competition and training. For example, when the active basketball rack and related sports facilities move on the floor, the surface and structure of the floor cannot be damaged.
