Polyethylene sheets or commonly known as P.E. films are widely used in construction industries as waterproofing material or permanent weather barrier.
Polyethylene sheets or commonly known as P.E. films are widely used in construction industries as waterproofing material or permanent weather barrier. Thin sheets of polyethylene are usually sold in roll form. The material does not rot, making it resistant to many chemicals. It is not damaged by extreme weather, which makes it a good choice for many kinds of outdoor applications, and the sheets can be reused many times.
Polyethylenes are semi-crystalline materials with excellent chemical resistance, good fatigue and wear resistance and a wide range of properties. Polyethylenes are easy to distinguish from other plastics because they float in water. Polyethylenes provide good resistance to organic solvents, degreasing agents and electrolytic attack. Polyethylene is used more than any other thermoplastic polymer. There are a wide variety of grades and formulations available that have an equally wide range of properties.
- Construction
Polyethylene sheets are used as vapor barriers and moisture barriers in construction projects.
They are employed as temporary protective covers for floors, walls, and surfaces during
construction or renovation activities.
- Packaging
Polyethylene sheets are widely used for packaging materials, including plastic bags, wraps, and
pouches. They provide protection against moisture and contaminants, ensuring the integrity of
the packaged goods.
- Geotechnical Engineering
Polyethylene sheets are utilized in geotechnical engineering for applications such as landfill
liners and covers. They serve as barriers to prevent the contamination of soil and groundwater
by waste materials.
- Insulation:
Polyethylene sheets are used as insulation material in the construction of homes and buildings.
They act as a thermal barrier, helping to regulate temperature and conserve energy.
