Overview

HDPE membrane as the main raw material (Polyethylene or Polythene) for the milky white translucent to opaque thermoplastic resin. HDPE membrane polymers are non-toxic, tasteless, odorless white particles, the melting point of about 110°C-130°C, HDPE impermeable membrane relative density of 0.941-0.965

Character:

Have good heat resistance and cold resistance

HDPE membrane has chemical stability, high rigidity and toughness

HDPE membrane has mechanical strength, and resistant to environmental stress cracking resistance tear strength and good

HDPE membrane impermeable maximum performance, with increased density, HDPE membrane mechanical properties and barrier properties will be a corresponding increase , heat, and higher tensile strength

HDPE membrane can be acid, alkali, organic solvents, such as corrosion

Type:

According to the density

*HDPE*LDPE*LLDPE

According to the surface

*HDPE membrane surface is smooth, film thickness uniformity, good tensile strength, high elongation at break, the general use of the complex geological conditions in the environment, anti-seepage performance, friction coefficient of small, the main application at relatively gentle slope on the friction coefficient of less demanding projects, projects and non-soil pools and other structures and seepage control projects require a higher application.

*HDPE membrane surface roughness noodles by irregular bump-like structure composed of circumstances than the same thickness of smooth PE film tensile strength of small, low elongation at break, high coefficient of friction, general application in the required slope membrane surface soil has a greater coefficient of friction requirements of the project, the application of appropriate thickness greater than the smooth.
