1,Good aging resistance,wide environmental temperature range and stable quality 2,High synthetic strength, competitive price
HDPE geomembrane Introduction
1,It integrates permeation, inverse filter and drainage functions and has various functions such as isolation and reinforcement.
2,It has high synthetic strength, large removal strength and high puncture resistance.
3,It has strong drainage capacity, large friction factor and small expansion factor.
4,It has good aging resistance, wide environmental temperature range and stable quality.
It is widely used in various projects such as water conservation, environmental protection, traffic and tunnel.
