DESCRIPTION:
Made from virgin PET (polyester)chips,the continuous filament was extruded from PET chip by machine directly by spunbond process, and then punch together to get the stable 3D with higher strength fabric.,So it has high strength,good creep property excellent and erosion resistance,aging-resistance and heat resistance.
Specification: 1. 100g/m2-800g/m2 2. 4m-6m in roll width,the length as clients' request
Property: Good creep property and hydraulics property,resistance to corrosion, excellent anti-aging and heat-resistance quality.
Production standard: GB/T17639-1998 JT/T 519-2004
APPLICATION:
1.Filtration of soils in drainage applications by retaining soil particles while allowing for the free flow of water
2.Separation and reinforcement in road and railway construction
3.Prevention of soil movement in erosion control measures
4.Cushioning and protection in many containment projects

Note E: specfications according to the fracture stvrength the actual specication isin the table betwen adiacent specifications,acording to the linear interpolation method to calculate the assessment index beyond this range,evaluation index is determined by the supply and demand sides negotiation.
Note 2:the actual fracture strength is lower than the standard strength,strength of the corresponding elongation does not meet the standard of judament
Note:3:eighth-ninth standard value according to the design or agreement. |
