Polyethylene PE has a waxy feel and is lighter in weight and has certain transparency compared to the same plastic. Polyethylene referred to as PE. It is a polymer of ethylene and is non-toxic. Easy to color, good chemical stability, cold resistance, radiation resistance, electrical insulation.
It is suitable for packaging materials for food and medicine, making utensils, medical equipment, and insulating materials for the electronics industry. Polyvinyl chloride, referred to as PVC. It is a polymer of vinyl chloride.
Polyvinyl chloride PVC is a synthetic material with many advantages and is an ideal material for engineering plastics. Polyethylene, by contrast, is a large chain of carbon atoms with only hydrogen atoms attached; there are no atoms of chlorine, oxygen or any other elements. While PVC always has the same basic structure, polyethylene forms into several different types based on the degree of branching from the main chain in each polymer.
Some types of polyethylene, such as low-density polyethylene, are highly branched, while other types have a more unbranched structure. Manufacturers create polyethylene and PVC through radical polymerization, in which a type of peroxide, splits into two radicals. One of these radicals attacks the double-bonded carbon group, which now becomes a radical and can go on to attack other double-bonded carbon groups in turn.
PVC, however, consists of subunits of vinyl chloride. Each vinyl chloride monomer has a pair of double-bonded carbons with a chlorine atom attached to one of them.
Polyethylene comes from ethylene subunits. Special catalysts used when making polyethylene ensure the chain stays unbranched, while no catalyst is needed with PVC. Additionally, PVC is much more fire-resistant than polyethylene, because the chlorine atoms it releases during a fire inhibit the process of combustion.
PVC in its native form is brittle and hard, so it needs softening and flexibility by adding other compounds called plasticizers. Polyethylene's properties depend on the type. PVC pipes are widely used for irrigation. However, HDPE is becoming an increasingly popular choice for golf course irrigation systems.
With end-to-end fusion, HDPE pipes are a safe decision. In places where digging is hard or impossible, HDPE is the best choice. HDPE has various uses. It is used for the distribution of natural gas, chemicals and petroleum products. Other uses include water, sanitary and storm sewer systems. Are you still looking for more information?
