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.
Consider a polyester Round Sling or a Twin-pathÂ® sling as an alternative when polyester web slings or nylon web slings are wider than 4 inches and 4 ply thick. Because polyester round sling and Twin-PathÂ® slings feature a body made up of multiple wraps of polyester yarn they do not choke lock.
