1.No rubbles. The bottom layer is made of single component Tire

recycling material, It is environmental protection product and has

good ventilation function. At high temperature, The steam from the

bottom layer will be evaporated in short time, The steam pressure

doesn't accumulate which consequently makes no bubble.

2.The top layer is made of EPDM granule. As a result it can resist

ultraviolet rays. It has good abradability and weather resistance.

3.No granule loss. The EPDM granules of top layer stirred with the

polyurethane adhesive and the prepolymer then sprayed by machine.

4.Stable elasticity. The elasticity of running track doesn't change

with seasons and meanwhile the track won't become soft in summer

or hard in the winter.

5.Good shock absorption, Safety, comfortable. It is good to develop

athlete potential and improve performance.
