product description

A double-sided, smooth, smooth HDPE geomembrane produced by a blow molding process from a specially formulated virgin resin.

 

Product specifications

The thickness is 1.0~3.0mm, the width is 4~9m, and the length is according to engineering design and customer requirements.

 

Features

Good flexibility and high anti-seepage coefficient;

It has strong weather resistance and excellent anti-aging properties;

It has high tensile strength and elongation at break index and strong strain force. It can be used under various harsh geological and climatic conditions, especially suitable for the construction of uneven geological settlement.
