Factory Price 15KN-200KN Plastic Road Geo Grid PP Biaxial Geogrid Uniaxial Geogrid

Uniaxial plastic geogrid uses polymer (polypropylene or high-density polyethylene) as the main raw material, adds nano-scale carbon black, extrudes a continuous sheet, punches regularly on the sheet, and then heats and stretches the screen. (one-way).

The stretching process makes the original scattered pore-distributed clusters of molecular chains re-aligned along the stretching direction, in a straight state, so that the tensile strength of the geogrid is greatly increased, the tensile strain and creep strain are significantly reduced, and the mechanical properties of material is improved.
