Benzene is an important organic chemical compound with the chemical formula C6H6. The benzene molecule is composed of 6 carbon atoms joined in a ring with 1 hydrogen atom attached to each. Because it contains only carbon and hydrogen atoms, benzene is classed as a hydrocarbon. Benzene is a natural constituent of crude oil and is one of the elementary petrochemicals. Because of the cyclic continuous pi bond between the carbon atoms, benzene is classed as an aromatic hydrocarbon, the second [n]-annulene ([6]-annulene).
Synthetic round slings offer a number of advantages for rigging purposes. The most commonly used synthetic round slings are made of nylon- or polyester-type yarns. Each synthetic material has its own unique properties. Certain synthetic materials perform better than others in specific applications and environments.
Synthetic fibers come from manmade processes and chemicals. Fibers such as polyester and nylon are made of chemical polymers spun into threads. However, some synthetic fibers come from natural sources. For example, modal and rayon come from wood cellulose that uses chemical processes to convert wood into fiber. Learn more about Sewing
