PET Geocell refers to a new type of geocell made from PET(Polyethylene terephthalate),a material with generally good chemical resistance,and a high degree of impact resistance and tensile strength.The orienting process serves to improve gas and moisture barrier properties and impact strength.PET sheets are joined by plastic moulding which leads to a much higher tensile strength than HDPE geocell,while the cost of PET geocell is not as much as HDPE.Also different specifications are available according to project requirements.
Comparison of geocells with different materials:
PE Geocell | PP Geocell | PET Geocell | |
Advantage | Good cold resistance Good chemical stability Acid and alkali resistance Oxidation resistance Non-toxic and odorless | Electrical insulation, Non-toxic and odorless Good chemical properties | Oil resistance Fat resistance, Acid resistance, Good impact strength High temperature resistance |
Disadvantage | Poor air permeability Poor ductility Easy to age, Easy to be brittle | Flammable, Low melting point, Poor adhesion | Poor corona resistance |
Salient Features | Most are embossed, perforated, mainly ultrasonic welding | Smooth surface Low color | Smooth surface Bright color |
Application | Highways, railways, airports, docks and other roadbed reinforcements; soft foundation treatment in desert areas; slope protection; landscaping projects; soil erosion control projects and large-scale pavement construction projects. |
