What is the difference between HDPE geomembrane and LLDPE geomembrane?

Release time:

2024-07-23

Geomembranes LLDPE (Linear Low Density Polyethylene) are made on the basis of Linear Low Density Polyethylene.LLDPE Geomembranes are elastic.LLDPE Geomembranes are used for the construction of structures in submerged soils, for locating unauthorised and abandoned landfill sites, for recycling of solid domestic and industrial waste landfill, for waterproofing of tunnels and other underground facilities. Because LLDPE geomembranes are flexible, they can solve tasks that rigid HDPE geomembranes cannot.

Geomembrane is a modern waterproof geomembrane, a polymer membrane. The raw materials used in the production of geomembranes are high-density and linear low-density polyethylene with the addition of carbon black, antioxidants and high-temperature stabilisers. Geomembranes are manufactured and supplied in rolls of various sizes. Geomembranes are supplied in rolls with widths ranging from 1 metre to 12 metres. Geomembrane thicknesses range from 0.2 to 3.0 mm, depending on specific project requirements.

Geomembranes are porous polymeric materials designed to reduce or prevent the passage of water or liquids through their structure. Depending on the composition of the raw material, they can be classified as polymeric geomembranes, clay geomembranes and bituminous geomembranes. Depending on the application, geomembranes are classified as glossy, textured and shaped.

Geomembranes - unaffected by decay, acids, alkalis or UV rays. Geomembranes have a service life of at least 50 years. High-density geotextiles are used to protect the geomembrane from mechanical damage. The technical properties of geomembranes enable them to be used in various fields of industrial and civil engineering, geotechnical engineering and environmental engineering.

Geomembranes HDPE (High Density Polyethylene) are made on the basis of High Density Polyethylene.HDPE geomembranes are high strength; HDPE geomembranes are used in the construction of waterproofing and anticorrosion coatings on surfaces of liquid and solid industrial waste storage facilities, solid waste landfill sites, concrete, bricks, metals, etc., including potable water tanks.

Geomembranes LLDPE (Linear Low Density Polyethylene) are made on the basis of Linear Low Density Polyethylene.LLDPE Geomembranes are elastic.LLDPE Geomembranes are used for the construction of structures in submerged soils, the location of unauthorised and abandoned landfill sites, the recycling of solid domestic and industrial waste landfill sites, the waterproofing of tunnels and other underground facilities. Because LLDPE geomembranes are flexible, they can solve tasks that rigid HDPE geomembranes cannot.

Depending on the specific project requirements, HDPE geomembranes and LLDPE geomembranes are available in thicknesses ranging from 0.2 to 3 mm. HDPE geomembranes and LLDPE geomembranes are available in rolls 5.0 or 6.0 metres wide. The length of the rolls depends on the thickness of the material.

HDPE geomembrane and LLDPE geomembrane main performance
- HDPE geomembranes and LLDPE geomembranes have high elasticity (relative elongation of HDPE geomembranes and LLDPE geomembranes can be up to 600%), high mechanical tensile strength, and resistance to puncture, impact and abrasion;

- HDPE geomembranes and LLDPE geomembranes are produced using only virgin raw materials (97% polymers and 2% carbon black), antioxidants and stabilisers, which makes HDPE geomembranes and LLDPE geomembranes UV-resistant, durable and oxidation-resistant.

- HDPE Geomembranes and LLDPE Geomembranes have high chemical and corrosion resistance to most aggressive environments (pH 0.5-14);

- HDPE Geomembranes and LLDPE Geomembranes are waterproof, non-swellable and resistant to plant root rot and germination.

- HDPE geomembranes and LLDPE geomembranes do not contain additives or fillers that accelerate the ageing process and reduce their physical and mechanical properties. HDPE and LLDPE geomembranes are therefore durable and unaffected by temperature fluctuations.HDPE and LLDPE geomembranes have an operating temperature range of - 60 °C to + 80 °C. They can be used in a wide variety of applications.

- HDPE geomembranes and LLDPE geomembranes isolate soil and groundwater contamination.HDPE geomembranes and LLDPE geomembranes are non-toxic, safe for human health and the environment, and do not require additional protective layers.
