Product Description
Product features
1. HDPE geomembrane is a flexible waterproof material with a high permeability coefficient (1× 10-17cm /s).
2. HDPE geomembrane has good heat and cold resistance. Its operating environment temperature is 110℃ at high temperature and -70℃
at low temperature.
3, HDPE geomembrane have good chemical stability, can resist strong acid, alkali, oil corrosion is a good anticorrosive material.
4. HDPE geomembrane has high tensile strength, which enables it to meet the requirements of high-standard engineering projects.
5. HDPE geomembrane have strong weather resistance and anti-aging performance, which can be used naked for a long time while
maintaining the original performance.
6, the overall performance of HDPE geomembrane, HDPE geomembrane has a strong tensile strength and fracture elongation, so that
HDPE geomembrane can be used in a variety of harsh geological and climatic conditions.Strong adaptability to geological
non-uniform subsidence stress.
7.HDPE geomembrane are made of high quality primary plastics and carbon black particles without any preservatives
