LLDPE - Linear Low-Density Polyethylene. Linear low-density polyethylene (LLDPE) is the newest member of the polyethylene family. LLDPE is a copolymer produced from the polymerisation of ethylene with a range of alpha olefins; the most common being 1-butene and 1- hexene. The linear structure formed improves the mechanical performance …

Very Low Density Polyethylene (VLDPE) is a type of LLDPE that contains a higher comonomer content which provides for lower crystallinity and lower density that more standard LLDPE products. VLDPE has a density in the range of 0.885 to 0.915 g/cm3. VLDPE offers improved puncture resistance, dart impact, tear resistance, low …

Metallocene linear low density polyethylene (mLLDPE - C8) Linear low density polyethylene is a polymer with significant numbers of short ramifications, commonly made by co-polymerization of ethylene with long-chain olefins. The linearity of LLDPE results from the different manufacturing processes of LLDPE and LDPE. Generally, LLDPE is produced ...

LDPE. Low density polyethylene (LDPE) resins from LyondellBasell are thermoplastics made from the polymerization of ethylene in autoclave or tubular reactors at very high pressures. Unlike low-pressure polymerization technologies, high-pressure polymerization allows the co-polymerization of ethylene with polar comonomers, such as vinyl acetate ...

Each LLDPE panel is approximately 4,000 pounds and depending on the thickness, very large panels of 25,000 square feet or greater can be prefabricated into one. The benefit of larger prefabricated panels is far fewer hours of installation in the field. The chart below compares the mechanical properties of 40 mil LLDPE to 40 mil HDPE.

Generally, LLDPE is produced at lower temperatures and pressures by co-polymerization of ethylene and alpha-olefins such as butene, hexene or octene. The co-polymerization process produces an LLDPE polymer having a narrower distribution in the molecular weight than LDPE and in combination with the linear structure, significantly other properties.

Sorption tests were conducted with LLDPE at 23 °C with c o = 263 μg/L for both PFOA and PFOS (c o < 0.0001CMC); a control test with no geomembrane was also assembled at the same time. These tests have been active for 226 days, and there have been small decreases in PFOA and PFOS concentrations observed in the vials …
