Chinese wholesale 1mm Hdpe Geomembrane - LLDPE Geomembrane – Yingfan

Product Description

LLDPE Geomembrane Liner is a kind of liner low-density polyethylene (LLDPE) geomembrane manufactured with the highest quality resin specifically formulated for flexible geomembranes. It is manufactured via triple co-extrusion technique by the most advanced automatic equipment which is imported from Italy.

Yingfan lldpe geomembranes all meet or exceed US GRI GM17 and ASTM standards. Its main function is anti-seepage and isolation. It is designed to be used when higher elongation properties are required. It is similar to HDPE geomembrane, but is lower in density, thus being more flexible.

LLDPE Geomembrane Liner

If you require increased frictional performance, flexibility and elongation, our LLDPE textured geomembranes are the best product choice. Our superior textured surface allows for increased friction between the two layers and the design of steeper slopes in many environmental and civil engineering.

Yingfan lldpe geomembranes are widely used in landfill, water consrevancy, minging&chemical industry, construction, aquaculture, agriculture etc.

Feature and Advantages of LLDPE Geomembrane Liner

♦ Excellent flexible and elongation properties
The break elongation of LLDPE geomembrane is better than HDPE geomembrane, which proves that its flexibility in the practical application of landfill capping is better than that of HDPE.

♦ High waterproof property:
It’s permeability property test value is ≤1.0*10-13g●cm/(cm2●s●pa),test method ASTM E96.

♦ Good anti-aging property
LLDPE geomembrane has high anti-aging, anti-ultraviolet, anti-decomposition capabilities. Oven aging at 85℃, standard OIT, 35% retained after 90 days, oven aging at 85℃,high pressure OIT, 60% retained after 90 days.

♦ High tensile strength
LLDPE geomembrane has high tensile strength, all meet GRI-GM17 standard.

♦ Economy
LLDPE geomembrane has obvious economical advantages compared with other traditional materials.

Types of LLDPE Geomembrane Liners

Generally Speaking, Yingfan LLDPE geomembranes have two types, one is smooth LLDPE geomembrane, another is textured LLDPE geomembrane according to the surface of LLDPE geomembrane.

Textured LLDPE geomembrane also can be divided into two types, one is both sides textured, another is one side textured one side smooth. Textured LLDPE geomembrane has better frictional performance.

How to installation LLDPE Geomembrane?
Shanghai Yingfan is the professional manufacturer specialized in R&D,produce,sales and installation of LLDPE geomembrane. We not only sell LLDPE geomembrane all over the world, but also provide overseas on-site installation service if you need.

The processes of install LLDPE geomembrane are as follows:

a. Laying LLDPE geomembrane,the laying base should be solid and flat.

b. Hot Welding: using welding machines, including plastic welding automatic wedge welder, plastic welding hand extrusion welder, and plastic welding hot air welding gun. The overlap of two pieces LLDPE geomembrane is about 10 cm. Adjusting the pressure,temperature and speed, then you can start.

How to Repair LLDPE Geomembrane ?
As we all know, LLDPE geomembrane is famous for its anti-seepage property, so when the LLDPE geomembrane is punctured or damaged by sharp objects or others, we need to repair it. If the damaged part is small, just clean the damaged part and its surroundings, and then use plastic welding hand extrusion welder to repair. If the damaged part is larger, you need to clean up the damaged part, measure the area of the damaged part, and then cut the repair material into a circular or oval shape (the area is about three times of the damaged part) covered on the damaged part to repair, generally using plastic welding hot air welding gun and plastic welding hand extrusion welder.

Shanghai Yingfan is the professional manufacturer specialized in R&D,produce,sales and installation of LLDPE geomembrane. We not only sell LLDPE geomembrane all over the world, but also provide overseas on-site installation service if you need.

How Long Does LLDPE Geomembrane Last ?
LLDPE geomembrane is a kind of liner low-density polyethylene (LLDPE) geomembrane, which is mainly used in waterproof and anti-leakage fields. The service life of the LLDPE geomembrane is related to product quality, specification, using method and using environment. Yingfan LLDPE geomembrane is made of high-quality low-density polyethylene with anti-aging agent added. If used in the dark, the service life can reach at least 50 years.

What Thickness LLDPE Geomembrane is Best?

HDPE vs LLDPE Geomembrane?
HDPE Geomembrane is high density polyethylene geomembrane,LLDPE geomembrane is liner low density polyethylene geomembrane.

According to the water vapor permeability test of ASTM E96, the permeability coefficients of HDPE and LLDPE are both less than 1.0*10-13g*cm (cm2*s*Pa). Therefore, both HDPE and LLDPE have excellent anti-seepage properties, they are both widely used in environmental friendly projects.

At the same time, thanks to the characteristics of polyethylene, both HDPE and LLDPE have good chemical resistance, and both can directly contact the toxic leachate in the landfill.

The properties differences between HDPE geomembrane and LLDPE geomembrane are as follows:

The break elongation of LLDPE is higher than that of HDPE, which proves that its flexibility in the practical application of landfill capping is better than that of HDPE, and it is more adaptable to uneven settlement in the landfill than HDPE. In terms of design and application, it is also safer.

The stress crack resistance of LLDPE geomembrane is better than HDPE geomembrane, because LLDPE geomembrane has lower density and better flexibility, so there will be no environmental stress cracking resistance problem. For this reason, in the standard of GRI GM17 of LLDPE geomembrane, the indicator of stress cracking resistance is not even included in the indicator category.

In other properties, such as puncutre resistance, tear resistance, oven aging and UV resistance, HDPE geomembrane is better than LLDPE geomembrane.
