Plastic Geogrid
Oct 27, 2017

Plastic geogrid is formed by stretching with a square or rectangular polymer mesh, according to its manufacturing when the direction of the different stretching can be unidirectional and two-way stretch. It is punched out of the extruded polymer sheet (mostly polypropylene or high density polyethylene), and then subjected to directional stretching under heating conditions. The uniaxially stretched grille is only stretched in the longitudinal direction of the sheet, and the biaxially oriented grating is to continue to stretch the unidirectional grating in the direction perpendicular to its length.

As the plastic geogrid in the manufacture of polymers in the polymer will be heated with the extension of the process of re-orientation, to strengthen the link between the molecular chain, to improve its strength purposes. The elongation is only 10% to 15% of the original sheet. If the addition of carbon black and other anti-aging materials in the geogrid, it can have a good acid, alkali, corrosion resistance and anti-aging and other durability.
