Paving Material on Polyurethane Plastic Cement Ground
It is made of polyurethane macromolecule material and designed in a particular way according to the special requirements at various places, the most popular paving material for playgrounds. It has the character of resistance to grinding and aging, with good elasticity and solid binding with the foundation, easy for maintenance and servicing. It is applied in the ground pavement of plastic cement track, various playgrounds, man-made grass playfield, nonprofessional athletic field and fallow green space.
Features:
• Elasticity: with considerable elasticity, the plastic cement surface course produce due rebounding for an athlete and protect his joints & ligament, resulting in less injury.
• Skid-proof: the granular layer of the plastic cement finishing coat can o bviously improve surface frictional force , providing safety and stability for an athlete. Its outstanding wet and slippery resisting performance enables an athlete to start, accelerate, run fast and safe .
• Antifriction: the excellent antifriction property can ensure the surface course stable and unchanged in structure.
• Stability: with good capability of combating ageing, durable for low temperature, humid & heat, ozone and ultra-violet ray, it can keep the physical mechanical property and outer structural characteristics standing forever, prolonging the service life.
• Application: it can be used in all weather, possible for training and matches even after heavy rain or washing out provided there is adequate drainage system, with no effects on its application.
• Maintenance: it is in bright color, with no need for special service. Regular washing out and cleaning will do. The Technical and Quality Index of Polyurethane Plastic Cement Ground: GB/T14833-93
