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 means that the rubber is made from crude oil, which also happens to be another nonrenewable resource. Nevertheless, the other type (natural rubber) can be harnessed from trees (i.e. rubber tree), in which a substance (latex) is then extracted. Although both are polymers, plastic and rubber differ because: 1. Rubber can be considered elastomers, and thatâs why when compared to plastics, they are naturally more elastic. 2. Synthetic rubber is derived from crude oil, whereas synthetic plastic is made of petroleum and natural gas.
