采用EDPM橡膠顆粒作為底層，聚氨酯底膠封底，聚氨酯面漆和膠漿作為面層鋪設而成，具有彈性好、色澤鮮艷、強度高、耐磨、防滑、耐低溫、防震隔音經久耐用等特點。由于其采用獨特的聚氨酯PU封底，在高寒地區雨雪延伸不進塑膠跑道彈性層，是我國高寒地區首選體育運動場地田徑跑道產品。

It is durable, and plastic runway material is preferred in cold regions

ZAKAT composite plastic runway adopts EDPM rubber particles as the bottom layer, polyurethane primer as the bottom layer, polyurethane top coat and glue as the surface layer. It has the characteristics of good elasticity, bright color, high strength, wear resistance, skid resistance, low temperature resistance, shock resistance, sound insulation and durability. Because of its unique polyurethane PU back cover, rain and snow can not extend into the plastic runway elastic layer in alpine regions, so it is the first choice of track and field track track products in alpine areas of China.
