High Strength 35kN/m - 200kN/m PP/PE Uniaxial Geogrid for Retaining Wall Reinforcement

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 creepstrain are significantly reduced, and the mechanical properties of material is improved.
