polüeteen

Polüeteen, also known as polyethylene, is a widely used thermoplastic polymer. It is synthesized through the polymerization of ethene monomers. The chemical formula for the repeating unit is (C2H4)n. Polüeteen is characterized by its relatively low cost, flexibility, chemical resistance, and low electrical conductivity.

There are several types of polüeteen, primarily distinguished by their density and branching structure. Polyethylene of low density (LDPE) has a highly branched structure, resulting in lower density and greater flexibility. It is commonly used for plastic bags, films, and flexible containers. Polyethylene of high density (HDPE) has a linear structure with minimal branching, leading to higher density and stiffness. HDPE is found in milk jugs, detergent bottles, pipes, and toys. Linear low-density polyethylene (LLDPE) offers a combination of flexibility and puncture resistance, making it suitable for stretch films and heavy-duty bags.

Polüeteen can be processed using various methods, including injection molding, blow molding, extrusion, and rotational molding. Its inert nature makes it resistant to many acids, bases, and solvents. However, it can be susceptible to degradation by ultraviolet radiation and strong oxidizing agents. Polüeteen is a recyclable material, and efforts are ongoing to improve its collection and reprocessing rates globally. Its versatility and cost-effectiveness have made it a staple material in numerous industries, from packaging and construction to agriculture and consumer goods.
