Products mixed plastic runway material hybrid structure, the surface layer of PU or EPDM granules weathering green color particles, the mother is part of the whole PU blending rubber particles. Construction process is simple, in line with standard international competitions, the standard thickness 13mm. 2 Technical parameters mixed plastic track features: all-weather use, any season and temperature, can maintain a high standard of quality, rain can be used immediately, increasing the use of time and improve site usage. Elastic: a moderate elasticity and rebound, can reduce physical consumption, enhance competition results. Impact resistance: moderately absorbing foot impact, reduce injuries, are suitable for long-term training and competitions. Weather resistance: not because ultraviolet radiation, ozone, acid rain, pollution and fading, chalking or soften, and long-term to maintain its bright colors. Wear: wear resistance of less than 2.5%, to meet all levels of school for a long time, the use of high frequency needs. Compression resistance: not because of the weight of track and field equipment can not restore elasticity. Anti-nail force: the force of the largest most frequently used by the meter starting point, it will not be spikes or starting frame damage. Impact resistance: a tough elastic layer and the buffer layer, can absorb strong impact, the surface will not be damaged. Flatness: Use self-leveling construction material, flat surface, can meet the special requirements of a flat playing field. Adhesion: Special construction treatment, strong bonding, can suppress the rising water, no blistering, peeling and other phenomena. Security: to prevent fall injuries occurred. Economy: easy maintenance, saving management costs. Color: special highly elastic EPDM and PU particles, surface color and soft, granular surface, preventing reflection glare of light, beautiful and durable, and multi-color matching.
