Product Description
Description of PET Needle punched Nonwoven Geotextile
Needle punched nonwoven Geotextiles are made of polyester or polypropylene in random directions and punched together by needles. GSNW Geotextiles has good impermeability and resistance to deformation, which allows geotextiles be widely applied in civil projects for separation,filtration,reinforcement, protection and drainage.

| 1) Specification is decided by mass-area ratio. When the practical specification is between the neighboring specifications in the table, the related check indicators will be calculated according to the interpolation method; if the product specification is beyond the table given scope, the check indicators will be decided by the supplier and demander. 2) Stand value is subject to the design or agreement. 3) If there is any alteration for the above technical data, we won’t give further notice. 4) Other specification is available as customer required. |

Features of PET Needle punched Nonwoven Geotextile
1)anti-aging, the product has very high anti-ultraviolet radiation ability, not easy to degradation.
2) High temperature resistance to up to 230℃ maintaining structure stability and original physical properties.
3) High flat drainage and vertical permeability.
4) High creep resistance.
5) Resistance of erosion of chemicals in soil as well as the corrosion of gasoline and diesel etc.
6) High elongation under certain stress, thus able to adapt to uneven and irregular bases.
